Circuit Description

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

This DTC indicates that the Engine Control Module (ECM) received a message from the Transmission Control Module (TCM) to turn on the Malfunction Indicator Light (MIL) due to a transmission related OBD-II failure. The ECM will send a message via the Controller Area Network (CAN) link to the Body Control Module (BCM) who will send a message over the class 2 link to the I/P cluster to turn on the MIL.
