CHECK GAGES

The instrument panel cluster (IPC) illuminates the CHECK GAGES indicator based on a class 2 message from the body control module (BCM). The BCM will command the CHECK GAGES indicator ON when the following occurs:

    • The fuel level falls to or below 5%
    • The engine coolant temperature is hot and exceeds 107°C (225°F)

The CHECK GAGES indicator displays in the IPC whenever any of the above listed conditions are present. If the CHECK GAGES indicator illuminates when the fuel gage and coolant temperature are operating normally, check for the proper operation of the BCM.

SHIFT INDICATOR

The instrument panel cluster (IPC) illuminates the shift indicator when the powertrain control module (PCM) determines that the vehicle should be shifted to the next higher gear. The IPC receives a class 2 message originating from the PCM via the body control module (BCM) requesting illumination.

THEFT SYSTEM

Security: Refer to Theft Systems Description and Operation in Theft Deterrent


Object Number: 676475  Size: GT

The instrument panel cluster (IPC) illuminates the service vehicle soon indicator during any of the following conditions:

    • The body control module (BCM) detects a Passlock failure. The BCM sends a class 2 message to the IPC requesting illumination.
    • The BCM detects a malfunction in the passive trunk release system. The BCM sends a class 2 message to the IPC requesting illumination.
    • The BCM detects a failure in the traction control system. The BCM sends a class 2 message to the IPC requesting illumination.
    • The IPC detects a mismatch between its part number and the vehicle platform configuration sent by the BCM via a class 2 message.
