Circuit/System Description

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

The transmission control module (TCM) uses the controller area network (CAN) to signal the engine control module (ECM) that the TCM is requesting malfunction indicator lamp (MIL) illumination. This occurs when the TCM determines a condition that affects emissions within the transmission control system. When the ECM receives the message from the TCM, DTC P0700 will set.
