Warning Chimes

Warning Chimes

NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

The warning chimes are designed to provide the driver with an audible warning that acts as a supplemental alert. The only deviation from this strategy is the air bag chime which is used to alert the driver that the primary alerting system (air bag warning indicator) is inoperative. The Instrument Cluster (IC) controls all warning chimes based on messages received from external modules.

The warning chime system consists of the following:

- IC
- Key-in-ignition warning switch (part of the ignition switch)
- Restraints Control Module (RCM)
- Door/liftgate ajar switch
- SJB

The following chimes are controlled by the IC:

- Active park
- Air bag warning
- Belt-Minder(R)
- Door/liftgate ajar
- Headlamps on
- Key-in-ignition
- Message center
- MyKey(TM) speed
- Parking brake on
- Safety belt warning
- Service Roll Stability Control (RSC(R)) warning

An audible tick-tock signal is also provided to indicate operation of the following systems:

- Turn signal
- Hazard signal
