WARNING DEVICES

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 does not operate. The instrument cluster controls all warning chimes based on messages received from external modules.

The warning device system consists of the following:
- Instrument cluster
- Safety belt warning indicator switch (part of the safety belt buckle)
- Door ajar switch
- Key-in-ignition warning switch (part of the ignition switch)
- Smart junction box (SJB)

The following chimes are controlled by the instrument cluster:
- Key-in-ignition
- Headlamps on
- Safety belt warning
- Air bag warning
- Turn signal/hazard
- Message center
- Parking brake applied
- Belt-Minder(R)
