Theory Of Operation
WARNING: This page is about a different variant/trim than selected.
The 12-volt voltage supply circuits for the transmission solenoids and pressure regulators are monitored for the following conditions:
- Open circuit
- Short to ground
- Short to voltage
If a failure is detected, the Transmission Control Module (TCM) will deactivate the affected power supply circuit and set a corresponding Diagnostic Trouble Code (DTC) relevant to the fault that was detected.
