Theory Of Operation

WARNING: This page is about a different variant/trim than selected.

Solenoid Monitoring:  The Transmission Control Module (TCM) measures the actual solenoid voltages and compares them to calibrated table to identify the following electrical failures. Short to battery, open circuit and short to ground in case the solenoid is switched on (i.e. commanded control value is 100%), the diagnostic can not distinguish between short to ground and open circuit. In that case the TCM status information is used to detect the failure.
