How to use GM Tech2 to do eeprom programming?

Connect Tech 2 to the vehicle.
Switch on Tech 2 – start screen appears.
Turn ignition (Do not start motor!).
Press “Enter” in the Tech 2 start screen.
Select “F1: Service Programming System” in the main menu and then “F1: Program ECU”.
Follow the instructions on the Tech 2 screen.
During the download the Tech 2 screen shows the message “Programming in Progress”.
At the end of the download the Tech 2 shows the message “Programming was successful”. The button “Exit” leaves the program. First, turn off the ignition of the vehicle, then switch off the Tech 2 and disconnect it from the vehicle.
Turn off ignition for 30 seconds before starting the motor. Additional information is available in the section “Check programming”.

Alternative Programming with “Pass Thru”

In addition to the procedure described above, there is an alternative programming mode called “Pass Thru”. In that case, the data are directly downloaded from the pc to the ECU in the vehicle.

Although the Tech 2 is still needed in that mode, the data entry and the download control is done directly at the pc. Altogether, that method is faster, and it is recommended when a pc with TIS 2000 is within 3m of the vehicle.

Connect Tech 2 to the vehicle.
Connect Tech 2 to the PC switch on Tech 2.
Start TIS 2000 on the PC.
Select the icon ‘Service Programming System’ (Fig. 1) on the TIS 2000 start page.
Start TIS 2000 on the PC.
On the screen ‘Select Diagnostic Tool and Programming Process’ (See picture below) make a selection for
***Pass-Thru mode

***the reprogramming of an ECU that was not exchanged or the replacement/programming of a new ECU

***the ECU location.

Then clock ‘Next’ button.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Check programming result

After every repgrogramming of an ECU a test to check the successful programming has to perform as follows:

Turn off ignition
wait for at least 30 seconds
start motor to confirm the successful programming
If the motor doesn’t start this points at an error. After the replacement of an ECU it has to be made sure that the necessary programming of the immobilizer was successful.
