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?

https://www.obd2tool.com/goods-1568-GM+Tech2+GM+Scanner+-CANdi++TIS+(Works+for+GMSAABOPELSUZUKIISUZUHolden).html

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.

GM Tech2 clone Automated Bleed 2006 C6 Feedback

I just checked my Tech II clone against my 2006 C6. In the ABS section there is an “Automated Bleed” option. In the Radio section there is a “VIN Relearn” option. I’ve never actually used either one, but I bet they work.

The clones are literally running the same software as the Tech II, so they have all the same functions. There are a few caveats: the standard clone power supply will cause the unit to reset if you run the starter motor, apparently, though this can be fixed. Also, operating while tethered to a PC involves a bunch of licensing hacks and other nonsense. But you only need to do that if you want to flash the ECU firmware.

The OBD II Scanner Tech II lets you see (and individually reset) all the DTCs from all the modules. It also has a bunch of special functions and bidirectional capabilities.

It’s great as a standalone diagnostics tool but it isn’t intended to modify ECU parameters like tuning software does. This is a tool for fixing the car, not modifying it.

How to use Tech 2 for Service Programming System (SPS)

GM Service Programming System manual:

The GM Service Programming System (SPS) is a personal computer (PC) application used to reprogram vehicle electronic control modules (ECMs). The SPS application programs General Motors programmable control modules by using the GM Tech 2 Flash scan tool or the Next Generation scan tool as a “pass-thru” device to communicate program data to the vehicle control module. All programming steps are activated and finalized through the PC Service Programming System software CDs

GM Service Programming System kit contains two compact discs (CD):

1.An Application CD which loads the SPS application
2.A Data CD which loads SPS data

System Requirements

29-1

SPS application install

Step 1: Determine if TCP/IP protocol is installed

– If you have a network card installed then you only need to verify that TCP/IP protocol has been configured.
– If your PC is already set up with TCP/IP protocol, go to “Install the SPS Software”

Step 2: Install the SPS Application CD software

To install the SPS software, follow these steps:

1 Insert the Application CD into the PC’s CD drive.

The TIS 2000 Installation Welcome window appears automatically

Note: If the Car Scanner TIS2000 software was previous installed and removed from the PC, a message may appear asking to reuse old settings. If so, click the NO button to NOT reuse old settings.

12 This begins the TIS2000 software installation and displays a progress indicator message. Wait for the installation to complete and for the completion message to appear (Figure 1.19).

13 Click the OK button.

14 Remove the Application CD from the PC’s CD drive.

15 Go to Update the SPS Data

Step 3: Update the data with the SPS Data CD

Note: During the update, the TIS2000 software skips the initial language, dealership, etc. steps and uses current TIS2000 settings. TIS2000 also skips over SecDevIns (Security Device Installer) and uses the current TIS2000 settings.

1 Insert the Data CD into the PC’s CD drive and wait approximately 20 seconds for the TIS2000 Update message to appear.

Note: On Windows XP systems, a browser window may open displaying the contents of the CD. If so, close the window and double-click the TIS2000 icon on the Window’s desktop. Because TIS2000 looks for new updates each time you start the application, the Update message appears.

2 Click the OK button to continue. This begins the update and displays a progress indicator message. When the update completes, a completion message appears

3 Click the OK button. The application is ready to use.

4 Begin using the SPS application by double-clicking the TIS 2000 icon located on the Window’s desktop.

Service Programming Cautions
CAUTION: There are a number of programming preparations that must be followed exactly or permanent
damage to a reprogrammable control module

could result:Battery voltage– The battery must be between 12.6 and 14 volts. The battery must be completely charged before programming.

Important: Do not program while charging the battery. Connecting a second battery in parallel to the vehicle battery helps prevent drawing the battery charge low enough to cause a fatal error to the vehicle ECM while programming.

Ignition key on, engine not running – One of the PC message screens requests that the ignition key be turned on, engine not running. Important: Do not turn the key to any other position until the programming is complete.Once programming is complete, turn the ignition key off, wait about 30 seconds, and then disconnect the tools. This allows time for the vehicle computer to power down properly.

Power interruption– Important: During programming,do not interrupt power or DLC connections in any way. This could cause permanent damage to the reprogrammable control module. Before programming, check all connectors and cords for wear, and check all connections to be sure they are secure. All cords must be properly routed and secure to prevent any entanglement with feet or hands.

Tampering– A new control module is not preprogrammed.The memory of an in-use reprogrammable control module contains the vehicle identification number (VIN) as well as calibration data. In the course of reprogramming an in-use control module, the VIN and the calibration date are replaced. The VIN entered into the scan tool must match the VIN on the vehicle’s VIN plate. It is important that the correct VIN be installed in the control module for future service and in the event of a recall campaign that requires reprogramming the module. Other information entered into the program must also be correct. Programming improper calibration data could adversely affect vehicle exhaust emissions resulting in violation of emission control laws and regulations.

Self-starting computer applications – ALL personal
computer applications must be turned off before you use the SPS application. A screen saver, virus detection application,network connections, or any other applications that can activate without user prompting must also be turned off to prevent any disruption in communication. Any disruption during the reprogramming function can cause a programming failure and damage the vehicle computer.

Current drain – Headlights and fans may be activated during the reprogramming steps. This can cause enough current drain to the battery to bring the battery voltage below an acceptable level for programming, or low enough to damage the vehicle computer. Set the parking brake to disable “automatic on” headlights. Remove the fuses for high current body electronic circuits, but do not remove the fuse for the vehicle computer circuit.

Doors may lock– During programming, leave a window open to enable access into the vehicle.

Customer real experience with GM Tech 2 Scanner (Review)

23-1

Here is the my real experience on gm tech 2 Scanner from obd2tool.com

Bought the highest quality version as i didn’t want to risk any issues with the device, and it all works fine and i do not regret my purchase.

It arrived pretty fast, but i got a £17 customs charge which i didn’t realise i’d get.

First impression: the carry case is not the one shown in the photo’s, which is annoying as the one in the photo’s looks really good, With the cables and candi module stored underneath 2 flaps, the main unit and adaptors clipping in the top of the case etc.

What i got was a basic plastic case (with sharp metal catches) where everything is squashed in on one level in foam, it does the job i guess, but i’d really have prefered the better case i thought i was paying the extra £30 for.

I’d bought a genuine Ugreen rs232 to usb cable in advance, £10 off amazon, this is one of the few cables listed as working with the tech2, and it did, connects at highest speed with no issues at all.

The house power supply has an american plug on it (psu has a universal voltage of 100 to 250 volts)
i got worried when the tech ii scanner wouldn’t even turn on, then i noticed the plug had slightly pulled out of the adaptor i had to use, something we are not used to in england as our plugs fit the sockets very securely and are hard to accidentally pull out, so changing the plug is one of the first things to do…
The house psu runs pretty warm btw.

I did all the self tests and it passed them all with flying colours (except the usual HBCC test that gets ignored (used on some ford vehicles i believe) and the RS485 that has no loopback adaptor so will always fail)

I took it out to my car (a 2011 vauxhall meriva B) and plugged it in, it connected straight away and i asked it to give me a list of DTC’s, i had been using an op-com before i got the Tech2 and the tech2 listed some old DTC’s the op-com had never picked up, I cleared the DTC’s, then tried the rest of the diagnostics available, i had no problems so far, i was able to move engine actuators (op-com can’t do that on the meriva B) operate things remotely, saw the DPF was at 108% full, so went for a little drive and the tech2 showed the DPF regen in progress, got an exhaust temp of 650 degrees C during it)

However that test drive showed up the universal weakness of the clone tech2’s, the internal power supply cuts out when you start the engine so the tech2 re-boots, this means there are a few diagnostic tests you can never do that involve starting the engine whilst the tech2 monitors things (unless you use external power to the tech2, which is advised against in all service manuals)

There is a solution, replace the internal power supply module with a better quality unit!!

There is also a highly recommended modification of removing the RS232 chip and putting a usb module in it’s place so you have a direct USB connection to the tech2, rather than the 4 connections that are just begging to be caught and pulled apart whilst uploading software to the car.
These mods are on the tech2 wiki (google it)

I then tried to SPS to my car to add a new IPC… one of the reasons i bought the Tech2.

That’s when discovered my car is not in the list of cars you use the tech2 to service program directly (the: connect tech2 to car, download data, take tech2 to computer, upload data, download software update, take tech2 back to car and upload the software method)

But i figured i could SPS using the tech2 in the J2534 pass thru mode… only my computer couldn’t connect to the tech2 in that mode… remote view of the unit worked but not SPS… i figured the issue out tho…
The rs232 to usb adapter had been assigned to com port 7 when i plugged it in, i changed the com port to COM1
~windows / computer / device manager / ports (COM & LPT) and find the relevant port your rs232 adapter is on (it wont be listed as ‘Tech2’) and change it to port 1~

Now SPS in pass thru mode works perfectly, i updated the software in a few of the modules (i use GlobalTis 32b, the last offline version with full SPS capability, was released in 2012 i believe, and it had newer software than my 2011 car had in it)

Then i did an update of the BCM and IPC to allow the rain sensor i’d just wired in to be seen by the systems, I tried to add a new immobilizer key, but it refused the accept the new key, most likely the key is at fault.. as part of learning new keys is to delete the old ones from the system, and the tech2 added them back no problem.

I’ve also used the tech2 to connect to ford vehicles using some software called ‘ForScan’ it has the Tech2 listed as a J2534 pass thru devise and works fine with it, The pcmcia card that came with the Tech2 allowed it’s self to be re-written (some people buying from other places find the card is locked and can’t be re-written)
i used GlobalTis’s card writer feature, it takes 40 minutes to write the card, but it works fine.

I’m very pleased with my Tech2 so far, the only thing that would make it perfect would be the carry case that’s shown in the photo’s, but that dosent affect how the actual devise works.

I’d recommend anyone buy their gm tech 2 scan tool from this shop, and i have pointed a few people who were interested in buying one here.

What’s Tech2 TIS2000 hardwaresecurity key used for

I have a question about the gm tech2 hardware/security key. What exactly is the purpose of it? I don’t have one, and was wondering if I can still use the TIS software without it.

Reply:

There are three versions of the hardware key:

the original green parallel port key,

the newer white Rainbow Technologies parallel port key

and now the USB key also made by Rainbow Technologies.

Normally the Car Scanner GM SPS software (TIS2000) as supplied by GM requires a hardware key for its SPS functions.

However most GM dealers now use a web based SPS system that links directly to GM’s database via a password protected secure GM website which do not a hardware key.

Some dealers still use a standalone SPS terminal which does require a key.

Without this key the software and its programming system is inoperative unless you have a hack for it.

All other functions of the TIS program will work without the key, if you have full blown TIS package it will include software that can download and playback data recordings done with the tech2 scanner for sale, it will also update a TECH2 with the latest software from GM.

GM Tech2 for ALL systems – HP Tuners only for ECM & TCM

What is GM Tech2:
The GM Tech2 Scanner, working with TIS2000 software, supports onboard diagnostics and full bi-directional control when performing powertrain, chassis and body diagnostics for GM/SAAB/OPEL/SUZUKI/ISUZU/Holden.

8-1

What is HP Tuners:
The HP Tuners vcm suite is the most feature rich, powerful and comprehensive vcm/PCM reprogramming and diagnostics package available on the market today. Vcm suite is the ultimate tuning tool designed for basic Tuners to advanced tuning shops.

8-2

GM Tech 2 vs. HP Tuners:
HPT can only work with ECM and TCM
Tech II can work with ABS, BCM, etc. (all systems)
But, Tech 2 can only change/do stuff GM intended where HPT can change all kinds of tables GM wouldn’t want us messing with
So both have pluses/minuses depending on what you want to do

Tech 2 scan tool:
confirmed to works good for ALL systems

I just checked my OBD2 scan tool Tech II clone against my 2006 C6. In the ABS section there is an “Automated Bleed” option. In the Radiosection there is a “VIN Relearn” option. I’ve never actually used either one, but I bet it works.
The Tech II clone is literally running the same software as the GM Tech 2 Scanner, so it has all the same functions. There are a few caveats: the standard clone power supply will cause the unit to reset if you run the starter motor, apparently, though this can be fixed. Also, operating while tethered to a PC involves a bunch of licensing hacks and other nonsense. But you only need to do that if you want to flash the ECU firmware.
The Tech II lets you see (and individually reset) all the DTCs from all the modules. It also has a bunch of special functions and bidirectional capabilities.
It’s great as a standalone diagnostics tool but it isn’t intended to modify ECU parameters like tuning software does. This is a tool for fixing the car, not modifying it.

same problem as recording images to the memory card via the Tech 2 and TIS

Hello everyone. A few days ago saw that often face the same problem as recording images to the memory card via the Tech2 Scan Tool and TIS.

4-1
Initially I thought this is a typical problem with MAX232, only a little deeper, I saw that the Tech 2 is well connected with TIS, but attempts to write through it, memory cards, success did not. Having started to study the problem, I found the following that through the card reader in your laptop works, and through TIS not. And that’s what this difference is expressed: the fact that the card reader work with cards with 3.3 Volts and 5.0 Volts. And that is what is written in the instructions to the Tech 2, the photo shows.
In the end, I checked everything with me in the presence of a memory card, here is their photo:

4-2
As a conclusion, until I found how to solve this problem, it is best card to rewrite only through the card reader in the laptop. Another way to try to lower the voltage in the Obd2 scan tool Tech 2 so that it more accurately worked with credit cards, there is a successful experiment, but there are very few tests that were carried out and what it may cause, or to try to slightly modify these memory cards.
Just want to try another experiment, but I still havent for it is only necessary, as only something I can do, or find a better solution will be described later.
