Circuit/System Description

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

The transmission control module (TCM) continuously monitors the system voltage on the Ignition 1 voltage circuits. Lower than normal voltage may be inadequate to operate the transmission control solenoids properly. Improper solenoid operation may cause erratic transmission operation, which may result in internal damage. Theses DTC detects high or low TCM voltage for an extended period.
