Tech2 Tool Remote Mode ECU TIS2000 Calibration Update

Here is the step-by-step instruction on programming GM (General Motors) ECUs with Tech2 scanner and SPS (Service Programming System) application in TIS2000.

This article is an overview on how to use the GM Tech 2 Scan Tool to perform GM SPS Programming of calibration file updates for the ECU or any programmable module firmware on the vehicle such as the EBCM, TCM, or Radio that you may want to reflash. Of the different reflash programming approaches, this first video covers Remote Mode between the Tech2 and the Techline terminal PC running TIS 2000. This procedure applies equally to the genuine Tech2 manufactured by Vetronix, HP, or Bosch as it does to any clone or knock-off model from China.

Warning: Pay very close attention to the instructions around power cabling and battery readiness as a power fluctuation during an SPS programming procedure can permanently damage a controller module.

TIS2000 was deprecated by GM in early 2008, but was once the primary Techline Information System approach delivered to dealers via DVD media on a quarterly basis. Today we would use the subscription based TIS2Web as part of the ACDelco TDS server based offering to accomplish many of the same tasks, although Tech2 Remote Mode is no longer supported or offerred by TDS for newer vehicles.

Note: be sure your USB to serial adapter device driver is configured for 115200 speed on Windows using Device Manager and that you set the COM port it is assigned to within TIS2000 for communication to be successful between the PC and the Tech2.

Applicable to OBD2 model years 1996 thru early 2008 only, and for all makes under General Motors such as Chevrolet, Buick, GMC, Cadillac, Oldsmobile, Pontiac, Hummer, Saturn, Opel, Vauxhall, and Saab.

GM TECH 2 Diagnostic tool – A quick word before buying on obd2tool

The Tech 2 Scan Tool has been around since the 1980’s.  It has been the flagship diagnostic tool and programing device for many many years.  it continues to be a valuable part of the GM dealership stable because its quick, efficient, and works great!  Now that other diagnostic programs that are, for the most part, only economically  viable for GM dealership technicians to use (like Tech2WIN) the cost of Tech 2 has come down a little bit over years past.  It is because the Tech 2 has been around for as long as it has that it is such a copied and cloned unit.  Couple this to the advent of obd2tool, allowing rip-off artists world wide to sell cloned duplicates, the glut of good people who want to work on their own cars and want a dealership level tool, and technicians who want to upgrade beyond a piece of crap generic scan tool for GM family cars, and what you are left with is a global marketplace where 95% of the stuff being sold here is a clone, or simply someone else’s headache!

All Tech 2’s are not considered equal. Tech 2 gives you unprecedented access to EVERY GM module and controller, provides the best and highest volume of vehicle data, and possesses the most bi-directional functionality of any diagnostic tool for GM family cars. There have been, however, a multitude of manufactures of Tech 2 over the almost 30 years it has been in production.  Very early Vetronix units had solder joint problems which caused random communication failures.  In addition to being an inconvenience, if this occurs during a programing event, you will be left with a garbage controller!  Later models are made by Bosch, who bought Vetronix.  They have cheapened the unit up so much that it is marginally better than a Korean clone.  As a matter of fact, most of the electronics are made in Asia or in Eastern Europe where most of the clones come from. This was done as a cost cutting measure.  The result is a slew of premature failures!  The units that reside in the “middle” time were made and marketed by others like Hewlett Packard and OTC.  These were the most reliable and durable units around.

Tech 2 is not only a diagnostic tool, it is also is capable of programing new and used programmable GM controllers, configuring functionality within modules and updating GM family cars with the most current programing.  You can gain access to programing on GM TIS on WEB website.  With very little effort, and cables that accommodate your type of PC, you can update or install programing in any GM family OBD II or CAN compatible vehicle.  Tech 2 can also be used on SAAB, Holden, Isuzu, even some Toyota vehicles with optional programing available through GM and accessible by anyone for weekly, monthly, or yearly subscription.

A new Tech 2 unit retails for well over $4000.00.  Anyone who tries to sell you a new unit for less is selling you a clone that DOES NOT work on every GM car, IS NOT of any quality and has a high failure rate.  Clone Tech 2’s frequently destroy vehicle control modules, and are a complete and total waste of money!  A lot of people buy a Chinese or Korean clone, and have no idea they have a clone!  If they sell it to you, they didn’t know it was a Chinese or Korean clone.  This is a highly cloned tool and even the original manufacturer(s) built some low quality units.  Make sure of what your buying BEFORE YOU SPEND YOUR HARD EARNED MONEY ON IT. Clone scan tools are very easy to spot if you know exactly what your looking for!  On Tech 2, there are tell-tale signs of a tool being a clone.  Clone units DO NOT print on the unit that it is a clone.  Clone units DO NOT say “made in china” or “made in Korea” or “made in Poland” on them,  They say “Made in the United States.”  The idea is that THEY ARE CLONES and thus are lying to make you think your getting an authentic unit, when instead, your getting a huge piece of crap that is, literally, worth pennies!  There are hundreds of these clones out here on obd2tool being sold by people all over the world.  There are private individuals who buy clones, either discover they have a clone and re-sell it as authentic, or have no idea its a clone and think its authentic.  They have no idea because they bought it, think they couldn’t figure out how to use it (when in reality, it didn’t work) and just re-sell it as authentic.  Either way, intentionally or nu-intentionality, you get stuck with it, and you may or may not know it until it burns out or destroys your cars computer costing you hundreds or thousands of dollars and untold hours and days of misery, just to save a few bucks!

To use a Tech 2 scan tool in this day and age, 90% of all software packages GM offers require a minimum 32 MB memory card.  A 10 MB card, although very useful for backup, data logging and flash programing, is useless for diagnostic programing for North American Operations (NAO), Saab, Isuzu, Suzuki and pretty much any of the other available software packages Tech 2 offers.

If you think that, just because your using a Tech 2 for your personal use, you can buy a cheaper import unit, think again!  I see HUNDREDS of these units thrown on the scrap heap every year.  They cannot be repaired and are non-serviceable.  Not all of these units will accept GM programing, thus cannot be updated.  They are of grossly inferior quality and have an extraordinary failure rate, and damage more cars than I can express to you.
A couple ways to spot a clone:

If the Professional Diagnostic Tool Tech 2 your looking at has no production date on the inside cover for the software card on the top of the scan tool, its a clone.  If there is no date, your looking at a clone!
If the “VOID” warranty sticker is opaque in appearance and difficult to read, its a clone.
If the Tech 2 has little white stickers over the case half’s on each side with the word “VETRONIX” and Chinese symbols denoting a date, its a clone.
Most clones are being sold from Asian or European countries.  Why would anyone be selling an item that was built here, shipped over there, and than put up for sale over there, to ship back here?
Finally, there are PLENTY of people here in the United States selling clones!  They buy a few hundred of them, and un-load them on unsuspecting people calling them “slightly used” or surplus.  If they have very little feedback, or the feedback looks like it was written by a a foreigner, your likely looking at a clone.

90% of the units on obd2tool are being sold by people who are intentionally selling you garbage, import clone units. They don’t print that they ARE clones, but they don’t print that they are NOT clones!  As long as their are ignorant people who are led only by the concept of saving a few pennies, there will always be clone items out here looking for an idiot to mate up with.  Of the other 10%, half of them are selling you a clone are have no idea they are selling you a clone because they have no idea what they have or they are un-loading an early or late domestically built model that they are trying to get off of because it has damaged their car or doesn’t work right most of the time.  Of that last 5% half of them are intentionally trying to rip you off!  You do the math!  Of one hundred Tech 2’s posted on obd2tool, both new and used, maybe 3 to 5 are the genuine article and are high in quality.
If your going to buy something for thousands of dollars, buy it from someone who has the answers, knows the product and has priced it properly.  Please use my experience to educate yourself on what your buying before you go shopping for it, and form your own opinions.  Take advantage of this information to get what you want and get it for a good price.

No matter what you decide to do, thank you for looking in and I hope this information helps you get what you want.

Tech 2 programs Hummer H2 above 2007

Tech 2 Scan Tool on Hummer H2 above 2007… Possible to do programming? what to do in that case?


Actually it does the programming just fine on newer than 2007 GM vehicles!

You must:

Pay for an ACDelco TDS subscription for vehicles above 2007 and you would use the CANDI module that comes with many of the Tech2’s for working with CAN bus vehicles. You can subscribe for as little as two days for $55.

This is ONLY needed if you want to program or update the software in a module.

ALL of the build in diagnostics and testing for vehicles up to 2013 works without the subscription or the older OBD-II scan tool TIS2000 software. You only need those for doing actual programming. The older TIS2000 software – that is what has the programming was discontinued in 2007. TIS2000 does have the actual programming for all vehicles up to 2007. After 2007 GM went to the TDS system.

You can also:

(for diagnostics and programming)

Get a newer style GM MDI or MDI 2 for diagnostics and programming. The catch with those. They have NO screen or built in software and you must pay for a subscription from from ACDelco TDS to use an MDI.

Other brand units, a very select few can do actual programming and use the pass-through method. NONE have the diagnostics that the actual Tech2 or MDI (with the subscription) will have. Check with Autel and see if they have the full diagnostics and re-calibration for the rear air suspension on a Hummer H2. Not going to happen, there is too little demand for them to hack and reverse engineer that particular bit of code in a Tech2 to figure out the diagnostics and then write programming for that for their tool.

(for programming)

For programming, you also need to have TIS2000 running on a computer or pay GM for a 24 month subscription for their TIS2WEB (Vehicle Programming) for $40
The computer will need a serial port for downloading the programming to the Tech2 for programming your vehicle.

How to do programming wit Tech 2:

The way programming works is you connect the Tech2 to the vehicle and tell it you want to program a module.

It interrogates all of the modules on the vehicle for the current versions and the VIN number.

You then connect it to the computer running TIS2000, GlobalTIS or TIS2WEB subscription and select programming in the computer.

It reads the Tech2 for the vehicle info and then presents you with a list of software for all of the modules and shows you which have updated software.


You’d better only do one module at a time which is a good bit more back and forth but safer.

The computer then loads the update to the Tech2. You take that back to the vehicle and connect it and it then programs the module.

The best, most reliable and safest method:

To use a long enough serial cable (its uses 9 pin serial adapters with an ethernet cable to make the cable longer – so you can just use a longer network cable) and do pass-through programming. In that method the process is the same but you leave the Tech2 connected to both the computer and the vehicle at the same time. Once you select programming on the Tech2 then go to the computer and you can immediately update each module right from the computer.

There is a slightly more updated version of standalone TIS2000 floating around on the web which has additional updates that has software updates for vehicles through 2009 as well. I know just using that TIS2000 both GMC truck and 2003 H2 both had a bunch of software updates available to be programmed all of which fix small issues or improve certain aspects.

One example in on the older single compressor air ride like 2003. Those would run and make small adjustments a LOT more often than needed and the software update fixed that.

On the H2 the rear air ride is also one to be very careful of for doing software updates though. For example, 2003 came with the earlier style single compressor but if it were to fail a dealership would replace it with the newer style dual pump compressor. Programming would still think its the original style and would attempt to program it and that would actually cause it to fail. TIS2000, (Global, Web, etc) will warn you about this sort of thing though so just heed all warnings and follow instructions and its fine.

The programming aspect is not needed or required to use the Tech2. The Professional Diagnostic Tool Tech2 still gives you a TON of diagnostics and tests that NO other OBD device has including things like the air ride module, detailed BCM functions, basically you can control and test every computer module in the vehicle.

Engine Vacuum Leak Symptoms and Solutions


If your vehicle has an engine vacuum leak, the air-fuel ratio in your engine will be higher than 14.7:1, also called a “lean” mixture. This ratio means that there is too much air in your engine, and as a result, the engine will run poorly or not at all. If you suspect that your vehicle has a vacuum leak, read on to learn the most common symptoms, as well as how to fix them.

Common Symptoms of an Engine Vacuum Leak

Engine vacuum leaks are commonly associated with the following symptoms, but keep in mind that this is not an exhaustive list.

Engine Running Problems

An engine with a vacuum leak could potentially run normally, but it may idle faster than usual, idle roughly, misfire, hesitate, or stall. You may find your vehicle doesn’t accelerate as well as it typically does. Major intake leaks might prevent the engine from starting at all.

Fuel Economy and Emissions

The lean air-fuel ratio will burn hotter and increase the generation of oxide emissions, such as nitrogen oxide (NOx) and sulfur oxide (SOx). Even if the check engine light isn’t triggered, the vehicle may still fail emissions testing. Drivers would also note reduced fuel economy as the engine controller attempts to compensate by adding more fuel. The evaporative emissions control system (EVAP) also depends on vacuum to function, so a vacuum leak in an EVAP valve or tubing might set an emissions diagnostic trouble code (DTC).

Check Engine Light

The engine control module (ECM) continuously monitors the environment in the engine. Using the manifold absolute pressure (MAP) sensor or mass air flow (MAF) sensor, among others, the ECM modulates fuel injector pulse, spark timing, and valve timing. If there is a vacuum leak, the ECM may be unable to compensate. Short-term or long-term fuel trim, STFT or LTFT on a scan tool Automotive Repair Software, might show something like +10% or +25% as the ECM attempts to compensate for unmetered air. P0171 and P0174 are common Fuel System Lean DTC.

Engine Damage

At its worst, long-term driving with a vacuum leak, elevated temperatures generated by running a lean air-fuel ratio could result in engine damage. Lean mixtures can detonate, damaging pistons and bearings. Higher than normal exhaust temperatures can also lead to catalytic converter meltdown.

Other Issues

Depending on where the vacuum leak is located, it could cause a variety of other problems. Some fuel pressure regulators are vacuum modulated, and so would jump to high pressure when vacuum is lost. This could result in fuel trim problems and a check engine light, possibly with Fuel System Rich DTCs, such as P0172 or P0175. Some older power steering systems idle-up the engine using a vacuum switching valve (VSV), but a vacuum leak might stall the engine during a parking maneuver. Many vehicles use a vacuum-actuated brake booster, reducing braking effort, but a vacuum leak here might make it harder to stop your car.

Identifying an Engine Vacuum Leak

There are several methods you can use to identify a vacuum leak. Start with a vacuum hose diagram, which you can find in a repair manual or sometimes on a sticker under the hood. Using one of the following methods, finding the vacuum leak might manifest itself as a change in engine speed or idle smoothness. Smaller leaks may only manifest themselves as fluctuating STFT readings on a OBD2 vehicle scanner.

Visual Check

A visual check is a good way to start, particularly with vacuum hoses and tubes. Exposed to extreme under-hood temperatures and oxygen in the atmosphere, rubber vacuum hoses and plastic vacuum tubes can become stiff or brittle, easily cracking or breaking. Similarly, rubber engine intake tubes can also become brittle, cracking and opening a way for unmetered air to get into the system. Physically manipulating these components with the engine running might reveal the leak.

Water Method

This is the simplest and cheapest method, as it utilizes just a simple spray bottle of water. With the engine running, spray water around suspected vacuum leak areas, such as vacuum hose fittings, intake manifold gaskets, and throttle plate bushings. A vacuum leak will suck in water, temporarily “sealing” the leak. This tiny amount of water won’t do any damage to your engine.

Carb Cleaner

Another method is to use a can of carburetor cleaner or intake cleaner spray. Please note that carb cleaner is flammable, so caution must be exercised and a fire extinguisher must be kept close at hand.. Sparingly spray the cleaner to suspect vacuum leak areas, while the engine is idling. If the leak is found, the engine will likely smooth out as the flammable mixture makes up for the lean air-fuel ratio.


This is a time-tested method for finding vacuum leaks, working on a principle similar to using carb cleaner. Use a small unlit propane torch, such as used for brazing or soldering, and a length of rubber hose. Poke the end of the hose around suspect vacuum leak areas with the engine idling. If the leak is found, the engine will probably speed up or smooth out as the flammable gas “compensates” for the lean AFR. Again, please note that propane is flammable, so caution must be exercised and a fire extinguisher must be kept close at hand.

Mechanic’s Stethoscope

Using a mechanic’s stethoscope with the probe removed and a length of hose, poke around suspected leak areas while the engine is running. Don’t forget to check around the vacuum brake booster, both in the engine bay and behind the brake pedal. Smaller leaks might be difficult to pinpoint, but a trained ear can pick up the distinctive hissing or whistling sound emitted by a vacuum leak.

Bubble Test

If you have access to an air compressor with a good regulator, introduce no more than 2 psi air into the intake with the engine off. (Under 2 psi is critical, as you can damage sensors or valves or create new leaks with higher psi.) Seal off the throttle body and exhaust, then use a soapy-water mixture to spray down the engine. Vacuum leaks may be revealed by the mixture bubbling up at the site of the leak.

Smoke Machine

This is the most expensive and safest method, but usually yields the best results. Not everyone has access to these expensive tools, but it may be necessary if the vacuum leak eludes you. With the engine off, plug the intake and exhaust and start the smoke machine injecting smoke into the intake. The harmless smoke, vaporized mineral oil, might take a couple minutes to fill the system, and will then start looking for ways to get out. A tiny plume of smoke will reveal vacuum leaks, so it’s best to do this test in an area free of drafts or wind.

Once you’ve identified the source of the leak, the obvious solution is to repair it, but it isn’t always a simple fix. Vacuum hoses can be replaced easily, as can sensor or tube O-rings, and some valves are also easy to replace. Other vacuum leaks might be more difficult and time-consuming, such as intake manifold gaskets or a faulty brake booster. As always, if you feel like the job is beyond you, check with your local trusted mechanic for professional assistance. Don’t forget to reset the check engine light when you’re done making repairs.

How to program fobik with wiTECH app

Confirmed! Chrysler wiTech MicroPod 2 clone is able to do online programming to Chrysler including ECU programming and key adding even when all keys are lost. Here you go.

Purpose: Micropod 2 clone programs new key fobik to Chrysler 200 when all keys are lost

Car: 2015 Chrysler 200 (The 2015 Chrysler 200, along with other Fiat-based models like the Jeep Renegade, Jeep Cherokee, and Ram Promaster, are all equipped with a rolling PIN Code.)

What you need:
Locksmith Identification Number (LSID through NASTF)
Proper keys to be programmed
PIN Code
MicroPOD II good quality clone or the genuine
wiTECH diagnostic application

Before you begin the programming process, you should the Key Code (key cut code) and Authorized PIN (key programming).


*   You must be online to program the key with OBD2 Scanner Micropod 2 clone.
*   You can pull the PIN Code with OBDSTAR F104 key tool.
*   If you input the wrong code for 3 times, it locks the BCM and you cannot service the vehicle for 24 hours.
*   The key is one-time programmable. Once married to the vehicle it is locked to the car forever. The key can be erased from the car and put back into the same car, but can’t be switched to another car.
*   The placement of the key during initialization is important. It needs to be placed either behind the shifter or in the center console.

How to program fobik with wiTECH app:

Step 1:

Plug the microPOD II adapter into the OBD port and connect the USB cable from the device to your laptop. This wakes the BUS on the car.

Step 2:


Manually enter the VIN of the vehicle. This gives you access to the module list.  Select the RFH (Radio Frequency Hub) module. This is the module where the key is registered.

Step 3:


Next select “Miscellaneous Functions,” then “Program Ignition Fobiks.”  At this point, you are prompted to enter the VIN again, followed by the four-digit PIN Code.

Step 4:


After the four-digit pin is entered you are prompted to hit continue to “Program Ignition FOBIK.” Once you hit continue you must press the UNLOCK button on the FOBIK within 30 seconds (the FOBIK needs to be located near the center console during this procedure).

Step 5:

GM Tech 2 works with Hummer Yes or No

This is about GM Tech 2 scan tool for Hummer troubleshooting and programming.

Can I have a cheap Tech 2 for Hummer?
Yep. Both the original and HQ clone can work for your car.

Where can I get a working clone at a good price?

Why my Hummer is not shown in the GM vehicle list?
That little short list is incorrect and only shows a few of the earlier than 2007 CAN bus vehicles.

Tech 2 clone for both troubleshooting and programming Hummer?
I’ve used my Tech2 on my 08 many times for troubleshooting not programming
But I think it should be able to program Hummer.

Anyone has good success of Hummer H3?
My H3 has had a CEL on – po452. I checked it with the tech 2. Well it pulls 3 codes, po455 (large evap leak), po442 (small evap leak), and po449 (vent solenoid control).

Tech 2 is possible to program for Hummer H2 above the year 2007… what to do in that case?

Actually it does the programming just fine on newer than 2007 GM vehicles BUT you must pay for an ACDelco TDS subscription for vehicles above 2007 and you would use the CANDI module that comes with many of the Tech2’s for working with CAN bus vehicles. You can subscribe for it.
This is ONLY needed if you want to program or update the software in a module. ALL of the build in diagnostics and testing for vehicles up to 2013 works without the subscription or the older TIS2000 software. You only need those for doing actual programming. The older TIS2000 software – that is what has the programming was discontinued in 2007. TIS2000 does have the actual programming for all vehicles up to 2007. After 2007 GM went to the TDS system.
You can also get a newer style MDI or MDI 2 for diagnostics and programming. The catch with those. They have NO screen or built in software and you must pay for a subscription from from ACDelco TDS to use an MDI.
Other brand units, a very select few can do actual programming and use the pass-through method. NONE have the diagnostics that the actual Tech2 scanner or GM MDI Scan Tool (with the subscription) will have. Check with Autel and see if they have the full diagnostics and re-calibration for the rear air suspension on a Hummer H2. Not going to happen, there is too little demand for them to hack and reverse engineer that particular bit of code in a Tech2 to figure out the diagnostics and then write programming for that for their tool.
