Engine Coolant Temperature Gage
The IPC displays the engine coolant temperature as determined by the engine control module (ECM). The ECM monitors the engine coolant temperature sensor. The IPC receives a serial data message from the ECM indicating the engine coolant temperature. The engine coolant temperature status message is also displayed in the DIC. The engine coolant temperature gage defaults to the lowest position possible if:
- The ECM detects a malfunction in the engine coolant temperature sensor circuit.
- The IPC will display the engine coolant temperature message on the DIC.
