Key-In Warning Alarm Circuit Description
The key-in warning alarm will sound if the following conditions occur
simultaneously:
• | The ignition key must be in the ignition switch |
• | The right hand (RH) front door is open. |
When the ignition key is in the ignition switch and the RH front door
is open, the ignition key alarm switch closes. The RH door jamb switch also
closes. When both of the switches close, the Body Control Module (BCM) senses
ground. When the BCM senses ground the key-in warning alarm activates. The
key-in warning alarm will stop sounding if 1 of the following conditions
occurs:
• | Removal of the ignition key from the ignition switch |
• | Closing the RH front door |
Fasten Safety Belts Warning Alarm Circuit Description
The fasten safety belts warning alarm will sound when the following
conditions occur simultaneously:
- The ignition switch is in 1 of the following positions:
- The right hand (RH) front safety belt is not fastened.
The BCM senses ground when the RH front safety belt is not fastened.
The alarm will sound for approximately 5 seconds. The inflatable restraint
sensing diagnostic module also senses ground when the RH front safety belt
remains unbuckled. Refer to SIR in Restraints for more information.
The BCM also incorporates an indicator within the instrument cluster.
The fasten safety belts indicator works in conjunction with the fasten safety
belts warning alarm. When the audio BCM receives a signal that the RH front
safety belt is unfastened, the BCM turns the fasten safety belts indicator
ON>
Lamps-On Warning Alarm Circuit Description
The lamps-on warning alarm will sound of the following conditions occur
simultaneously:
• | The headlamp switch is in the HEAD or the PARK position. |
• | The panel dimmer switch is not in the fully dim position. |
• | The ignition switch is in 1 of the following positions: |
When the headlamp switch is in the HEAD or the PARK position, voltage
applies through the ILLUM FUSE 12 to the BCM. When the lamps
ON input terminal of the BCM senses voltage and there is an
absence of voltage at the ignition ON input terminal, the lamps-on warning
alarm will sound. You can silence the lamps-on warning alarm by either
turning the headlamp switch to the OFF position or turning the ignition
switch to the RUN position.
