Action Taken When the DTC Sets
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
- The TCM does not illuminate the malfunction indicator lamp (MIL).
- The TCM enters PC solenoid valve diagnostic retest mode. The retest mode conducts the following diagnostic routine:
- The TCM de-energizes the PC solenoid valve, resulting in maximum line pressure.
- After being de-energized for 2 seconds, the TCM commands the PC solenoid valve ON at 0.1 amp for the retest period of 5 seconds.
- If no circuit faults are detected during the 5 second retest period, then the PC solenoid valve is returned to normal operation and DTC P0961 diagnostic is passed.
- If a circuit fault is detected during the 5 second retest period, then the TCM de-energizes the PC solenoid valve for 2 seconds before reentering the retest mode.
- If a circuit fault is detected 5 times without returning to normal operation, then the PC solenoid valve is de-energized for the remainder of that ignition cycle.
- If a circuit fault is detected 3 times during normal operation, then the TCM de-energizes the PC solenoid valve for the remainder of that ignition cycle.
- The TCM freezes transmission adaptive functions.
- The TCM records the operating conditions when the Conditions for Setting the DTC are met. The TCM stores this information as Failure Records.
- The TCM stores DTC P0961 in TCM history.
