What can I do with a GM Tech2 on Chevrolet C5

This is a write-up for those with a GM Tech 2 Scan Tool on Chevrolet C5

Tech 2 scanner is a diagnostic tool for the most part. It can be used to program out/in certain RPO’s in the BCM and can be used to bleed the ABS brake system without introducing air into the system. The extent to which it can be used to tune a Chevrolet C5 is that if you have a PCM Image that will work for your car you can save the current PCM Image and flash the new one you have onto the PCM. It cannot go in and individually change the tuning tables in the PCM as can say either EFI Live or HP Tuners tuning tools. But then those tools cannot touch the BCM either.

If you do or plan to do a lot of Professional Diagnostic Tool work on your car it can be a worthwhile tool. Most of the diagnostic charts in the factory service manual assume the availability of a Tech 2. But you have to learn to use the tool like any other computerized diagnostic tool. It has layers and layers of menus to wade through. But in certain diagnostic situations it can be an invaluable tool because it allows you to turn on and off hundreds of computerized settings to aid in the diagnosis process.

GM intentionally dumbed down the capabilities of the Tech 2 to change things to avoid law suits due to an errant technician that changed engine or emissions settings that could result in engine damage or emissions violations.

GM Tech2, the bi-directional scan tool can access all the 10 computers in the c5 corvette. That means it can scan for DTC codes, allow the adding or removing of most accessory codes like turning off the mag ride shocks to install regular schocks, fixing window regulator problems, etc. For Bi-directional it can active the ABS system to flush the brake fluid, reset the Long Term Fuel Trims, eliminate the 1-4 shift on manual trans, etc. It cannot make changes (like a tune tool) to the transmission or engine management system. For the avid DIY’er it is a great tool.
In the C5, the “computers” (technically they are modules) and they communicate over the OBDII compatible DLC data bus to each other. The range from you radio to your ride control, to your HVAC system. Even the Bose head unit talks to the PCM and BCM through this bus, but the CD changer talks over a “private” data bus to the head unit.

The Sensor Modules that can be pulled up from the DIC are:
PCM, BCM, TCS, RTD, IPC, HVAC, LDCM, RDCM, SCM, RFA, and SDM.
Only those C5’s with RPO F45 or F55 will have RTD.

Reference: Here is a very useful OBD2 Scanner TECH2 pathing document that you can use to figure out how to get to the end result that you need to test.

Control Module Stand-Alone Programming Adapter (J-45211) for Cadillacs

9-1

The J-45211 control module stand-alone programming adapter (Figure VIIC-41), also called the PCM programming adapter harness, is used to connect the Tech 2 to a vehicle’s PCM and perform SPS functions for the 2000 or later Cadillac models DeVille, Seville, and Eldorado. The J-45211 isolates the PCM from a vehicle’s electrical system so that the activity of other on-board computers cannot interrupt the communication between the Tech 2 and the PCM.

NOTICE: Failure to maintain unbroken J-45211 connections (PCM, Tech 2, power, and ground) throughout the entire programming procedure may cause an interruption, resulting in PERMANENT PCM DAMAGE

Procedure for Using the J-45211 Tool:
1.  Ensure that the Techline terminal and the GM Tech2 Scanner are updated with their latest respective software.
2.  Turn the vehicle ignition off and remove the key from the ignition lock cylinder. Turn off all electrical power consumers and accessories.
3.  Open the hood and measure the battery voltage directly at the battery positive and negative terminals using the J-39200 digital multimeter. If the negative battery terminal is inaccessible, or the battery is notlocated under the hood, check the voltage between engine block ground and the underhood “+” junction block.
4.  If the vehicle’s battery voltage is not 12.0 volts or higher, charge the battery before continuing. When finished charging the battery, disconnect the charger from the battery before programming the PCM.
5. Locate the PCM and disconnect the vehicle harness connectors from the PCM.
6. Connect the J-45211 harness connectors to the PCM.
7. Connect the J-45211 power clips directly to the vehicle battery terminals. If the battery terminals are inaccessible, or the battery is not located under the hood, then connect to the engine block(ground), and to the underhood source of vehicle battery’s positive 12-volt power.
8. Observe the red battery LED on the J-45211. The red LED should remain lit whenever the J-45211 is connected to the battery voltage. If the red LED does not illuminate, check the tool’s five-amp fuse. If the fuse is good and yet the red LED will not illuminate,for assistance.
9. Toggle the power switch on J-45211 to apply ignition voltage to the Auto Scanner Tool.
10. The yellow and green LEDs should illuminate when the power switch is toggled on. The yellow LED monitors the ignition voltage being applied to the control module. The green LEDs are a feedback signal from the control module indicating that the modules’s internal circuits are operating.
11. Connect the Tech 2 to the J-45211 and enter Service Programming System.
12. Select and perform Request Information.
13. After the Tech 2 has completed the information request, toggle the J-45211 switch off.
14. Turn off the Tech 2 and disconnect it from the J-45211.
15. Connect the Tech 2 to the Techline terminal. Download the new PCM calibration into the Tech 2 using the Techline terminal and TIS software. After the download into the Tech 2 from Obd2tool.com is complete, disconnect the Tech 2 from the Techline terminal.
16. Reconnect Tech 2 to J-45211 and toggle the tool’s power switch on.
17. Enter Service Programming System, and select and perform Program.
18. After programming is complete, toggle the J-45211 switch off, and wait until the green LEDs turn off before continuing or disconnecting any connectors.
19. Turn off the Tech 2 and disconnect it from the J-45211.
20. Disconnect the J-45211 from the PCM.
21. Disconnect the power clips from the vehicle battery terminals.
22. Reconnect the vehicle harness connectors to the PCM and reinstall PCM.
23. Connect the Tech 2 to the DLC connector under the instrument panel, and start the engine.
24. Turn the Tech 2 on, “build” the vehicle, and select Diagnostic Circuit Check, then Clear All DTCs.

Note:This will clear all DTCs in all control modules simultaneously.

25. If the Service Engine Soon light comes back on after clearing  DTCs, another problem may be present or a CKP System Variation Learn Procedure may need to be performed. Follow existing service manual procedures.

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

NOTE:

Before using the SPS, make sure that the GM Tech 2 Scan Tool and the pc contain the latest software, the battery of the vehicle is fully charged, only the ignition is on power,
and all cables are connected properly. TIS2000 will not work on 2007 up GM, and software must work together with TIS2000 USB key. If you need to program Saab ECU,
you had to use Saab TIS2000 and USB dongle.

Main steps:

Step 1: Instruction for TIS2000 software

Step 2: Data request

Step 3: Data exchange

Step 4: Program ECU

Alternative Programming with “Pass Thru”

Check Programming result

Step 1: Instruction for TIS2000 software

1.Connect the Tech II to the pc.

Note: The hardware key (HWK) has to be registered prior to working with ‘Service Programming System’. To register a hardware key, the form that is enclosed with
the hardware key kit has to be filled in and sent to the address at the top. In case the form is missing, the document is also in the TIS 2000 newsletter (see icon in the
TIS 2000 tool bar). At first, the user receives a temporary code until the key is registered on the next TIS 2000 CD.

Hardware keys that have already been registered are still valid!

To register the hardware key select ‘Hardware Key Registration’ in the menu ‘Configuration’.

TIS2000 installation video guide

2.Start TIS 2000 on the pc.
