INDICATORS AND WARNING MESSAGES
Refer to Indicator/Warning Message Description and Operation.

ENGINE COOLANT TEMPERATURE GAGE
The IPC displays the engine coolant temperature as determined by the PCM indicating engine coolant temperature. The engine coolant temperature gage defaults to 160°F (75°C) or below if there is a malfunction in communication, and a warning message will appear in the DIC.

FUEL GAGE
The IPC displays the fuel level as determined by the PCM. The IPC receives a Class 2 from the PCM indicating the fuel level percent. The fuel gage defaults to empty if the PCM detects a malfunction in the fuel level sensor circuit.

When the fuel level is less than a pre-determined value, the low fuel message in the DIC illuminates.

SPEEDOMETER
The IPC displays the vehicle speed based on the Class 2 information from the PCM. The speedometer defaults to 0 mph (0 km/h) if a malfunction in communication exists.

TACHOMETER
The IPC displays the engine speed based on Class 2 information from the PCM. The tachometer defaults to 0 rpm if a malfunction in communication exists.
