Warning Chimes

Warning Chimes

The warning chime sounds to remind or alert the driver:

- to turn the headlamps off when exiting the vehicle.
- to remove the ignition key when exiting the vehicle.
- to close the doors after starting the vehicle.
- to fasten the safety belt after starting the vehicle.
- that a fault is present in the Supplemental Restraint System (SRS).
- that a warning message is displayed on the message center (if equipped).
- that an engine coolant over-temperature condition is present.

The Lighting Control Module (LCM) controls the warning chime function using various inputs to determine when to sound the warning chime. The warning chime sounds if:

- the headlamps are on with the key removed from the ignition lock cylinder and the driver door ajar.
- the key is in the ignition lock cylinder in the OFF position with the driver door ajar.
- a door is ajar with the ignition switch in the ON position.
- the safety belts are not fastened with the ignition switch in the ON position.
- the ignition switch is in the ON position and an air bag warning chime request is received by the Instrument Cluster (IC) from the Restraints Control Module (RCM).
- the message center displays a warning message (if equipped).
- a fail safe cooling chime request message is received from the IC by a request from the PCM.
