Ford Focus Service Manual: Warning Chimes - Description and Operation
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 to the Instrument Cluster (IC) indication and message center warnings. The only deviation from this strategy is the air bag warning chime, which is used to alert the driver that the primary alerting system does not operate. The IC controls all warning chimes based on messages received from external modules.
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)
- Key-in-ignition warning switch (part of the ignition switch)
- SJB
The following chimes are controlled by the IC :
- Air bag warning
- Belt-Minder®
- Door/trunk ajar
- Headlamps on
- Key-in-ignition
- Message center
- MyKey™ speed
- Parking brake applied
- Perimeter alarm
- Safety belt warning
- Turn signal/hazard
- Turn signal left on
