Circuit/System Description
WARNING: This page is about a different variant/trim than selected.
The transmission control module (TCM) has a built-in temperature sensor to detect possible over-temperature conditions of the TCM. This fault indicates the TCM is in an overtemperature condition and the TCM has shut down to protect from possible heat damage. The TCM will remain off until the over temperature condition no longer exists. The TCM is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately.
