Coolant Temperature

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The driver information center (DIC) displays the engine coolant temperature as determined by the ECM. The instrument panel cluster (IPC) receives a serial data message from the ECM indicating the current engine coolant temperature.
