9.16 DTC B0981 – 3rd Start Switch Signal
Malfunction
DTC Description
This diagnostic procedure supports DTC B0981 – 3rd Start Switch Signal Malfunction.
Circuit Description
The 3rd start mode switch is a normally open switch that closes when the switch is activated. W hen activated, the switch
supplies signal ground to the 3rd start ground signal circuit. The powertrain interface module (PIM) converts the signal
ground input into serial data, which is used by the automatic transmission control module (TCM) to enable or disable the
3
rd start mode, and by the instrument cluster to display power mode status.
Additional Information
• For the 4L60E automatic transmission, refer to 7C1 Automatic Transmission – 4L60E – General Information:
• Power mode switch description, operation and inspection procedure, and
• TCM wiring diagram.
• Refer to 6 W iring Diagram and Connector for the following information:
• PIM connector illustration and terminal assignment, and
• PIM wiring diagram.
• For intermittent fault conditions, refer to Intermittent Fault Conditions.
• Since fault conditions in a wiring connector may trigger DTCs, always test the connectors related to this diagnostic
procedure for shorted terminals or poor wiring connection before replacing any component. Refer to 8A Electrical -
Body and Chassis for information on electrical fault diagnosis.
Conditions for Running the DTC
Conditions for running the DTC are:
• The ignition is switched on.
• The ignition voltage is 10.0 – 16.0 V.

11 Service Operations
11.1 Safety and Precautionary Measures

The following safety and precautionary
measures must be followed when servicing
and diagnosing the powertrain interface
module (PIM) System. Otherwise, personal
injury and / or improper braking system
operation may occur:
• W hen using electric welding equipment, disconnect the wiring harness connector from the PIM.
• Never disconnect or reconnect the PIM wiring harness connector when the ignition is switched ON.
• Do not touch the PIM connector pins or soldered components on the PIM circuit board to prevent possible
Electrostatic Discharge damage.
• To avoid wiring connector terminal damage, always use suitable wiring harness test leads (such as those in Tool
No, J35616) when performing tests on the PIM wiring connector.
• The PIM is extremely sensitive to Electro Magnetic Interference (EMI). Ensure the PIM wiring harness is routed
correctly and securely fitted to mounting clips when performing service procedures.
• Due to the sensitive nature of the PIM circuitry, specific wiring repair procedures have been developed. These
procedures and instructions are detailed in 8A Electrical - Body and Chassis and are the only recommended and
approved wiring repair methods.
• Ensure that all wiring harness connectors are seated correctly.
• Never disconnect the battery from the vehicle electrical system while the engine is running.
• Always disconnect the battery from the vehicle electrical system before charging.
• Do not use a fast charger for starting the vehicle.
• Ensure the battery cable terminals are secure.
• Before installing a new PIM, ensure the correct type is fitted. Always refer to the latest spare parts information.
11.2 Powertrain Interface Module

Do not touch the powertrain interface module
pins as Electrostatic Discharge (ESD) damage
may result. For further information on ESD,
refer to 1.2 Warning Caution and Notes.

When replacing the PIM, the PIM must be
reset prior to removal. Failure to perform this
procedure will result in the inability to:
• Test the PIM for warranty purposes.
• Install the PIM into other vehicles.

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 .

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.
