Warning Chimes

Warning Chimes

The warning chimes are designed to provide the driver with an audible warning that acts as a supplemental alert to the Instrument Cluster (IC) indication. The only deviation from this strategy is the air bag warning chime, which is used to alert the driver that the primary alerting system (air bag warning indicator) does not operate. The IC controls all warning chimes based on inputs and messages received from external modules and sensors.

The warning chime system consists of the following:

- IC
- Safety belt warning indicator switch(es) (part of the safety belt buckle)
- Door ajar switch(es)
- Headlamp switch
- Key-in-ignition warning switch (part of the ignition switch)
- Generic Electronic Module (GEM)
- Parking brake warning indicator switch

The following chimes are controlled by the IC:

- Air bag warning
- Autolock acknowledge, enable and disable
- Belt-Minder(R)
- Door ajar
- GEM service mode
- GEM Transmitter Identification Code (TIC) programming
- Headlamps on
- Key-in-ignition
- Not in park
- Safety belt warning
- Turn signal (tick-tock)
