12 PIM Security and Programming
12.1 Security and Programming Information
Car Pass Card
W hen performing certain powertrain interface module (PIM) programming functions using Tech 2, you may be prompted
to enter a four digit Security Code (1). This information is found on the car pass card issued with the vehicle when new. If
the card is unavailable, contact the GM Holden Technical Assistance (TAS) centre to obtain the relevant Security Code.
Security Code
The security code is required when performing certain PIM, ICU and ECM programming functions. W hen Tech 2
requests the security code to be entered, and an incorrect code is entered, the PIM will go into a security wait time stage.
This wait time stage will prevent any further attempts to enter the security code until the wait time has elapsed.
Should a second incorrect security code be entered after the initial wait time has elapsed, the PIM will go into a second
wait time stage. The wait time will increase each time an incorrect code is entered. W hen the correct code is entered the
wait time will reset back to its original value of 10 seconds.
NOTE
The ignition switch must be in the ON position
with the battery connected during the wait time
period.
The wait time stages are as follows:
• Stage 1 = 10 seconds.
• Stage 2 = 10 seconds.
• Stage 3 = 10 minutes.
• Stage 4 = 20 minutes.
• Stage 5 = 40 minutes.
• Stage 5 = 80 minutes.

Tech 2 PIM Security Information Data List
The Tech 2 PIM Security Information Data List displays the PIM's current security status.
To view the data list:
1 Connect Tech 2 to the data link connector (DLC) and turn the ignition switch on.
2 On Tech 2 select: Body / Powertrain Interface Module / Security / Security Information .

The Tech 2 PIM Security Information Data List
typical display values are obtained from a
correctly operating vehicle under the following
conditions:
• ignition switched on,
• engine not running, and
• vehicle is stationary.
Tech 2 Parameter Units Displayed Typical Display Values

Security Code Reset Counter 0 0
12.2 PIM Reset Procedure

Do not perform the reset procedure within
sixty seconds of turning the ignition switch
on. Failure to comply may result in the PIM
failing to reset.
W hen a PIM has been installed into a vehicle, it is security linked to the immobiliser control unit (ICU) and engine control
module (ECM). Once this linking has been performed, the PIM cannot be installed in any other vehicle, unless the
security linking between the ICU and the ECM has been reset using the following procedure:
1 Prior to resetting the PIM, obtain the Security Code. For further information, refer to 12.1 Security and Programming Information.
2 Connect Tech 2 to the data link connector (DLC) and turn the ignition switch on.
3 On Tech 2 select: Body / Powertrain Interface Module / Security / Reset PIM .
NOTE
When Tech 2 requests programming approval,
obtain TIS approval.
NOTE
If a Tech 2 screen displaying Security Wait Time
Active, Please Wait! appears after selecting the
Reset PIM option, an incorrect security code has
been previously entered. Refer to 12.1
Security and Programming Information for further
information.
4 W hen Tech 2 displays Enter Security Code, enter the security code, press the Enter key and then the Okay soft
key.

The engine will not start after the PIM has
been reset.
5 W hen Tech 2 displays Do you really want to Reset? , press the Reset soft key.
