Audible Warning Device: Description and Operation
Chime
General Informations
The audio alarm system brings the driver's attention to one or more of several conditions:
1. Lamps are on, ignition switch is set to "LOCK," "OFF" or 'ACCY," and driver's door is open;
2. Ignition key is in ignition switch and is set to "LOCK," "OFF," or "ACCY," and driver's door is open;
3. Safety belt is unbuckled and ignition switch is in "RUN," "BULB TEST," or "START;" and
4. A turn signal is left on and vehicle has traveled over 1.2 km (3/4 mile);
5. Park brake has been left engaged and either vehicle has traveled approximately 50 feet (indicators cluster) or vehicle is shifted out of "PARK" or
"NEUTRAL" (gages and digital clusters). The Multi-Function Chime (MFC) module is also used as the audible alarm for the reminder package
(Y67).
Voltage is applied at all times through I/P Fuse Block Fuse 9C to Multi-Function Chime (MFC) module terminal Al to power the module. Voltage is
applied at all times through I/P Fuse Block Fuse 6C to the head/park lamp switch. Voltage is applied through the head/park lamp switch in "OFF" to the
lamps off input of the module.
With the ignition switch in "RUN," "BULB TEST," or "START," voltage is applied through I/P Fuse Block Fuse 1D to module terminal A3.
Lamps on Chime
If the LH front door is open and the Multi-Function Chime (MFC) module does not sense voltage at the lamps off input (terminal AS) and there is no
voltage at the ignition on input (terminal A3), the fast-pulsed lamps on chime is sounded.
Key In Ignition Chime
The key in ignition chime is sounded with the key in ignition switch and the driver's door open. When the ignition key warning switch and the LH front
door lock assembly switch are closed, the Multi-Function Chime (MFC) module senses ground at the key in ignition and the medium-pulsed chime is
sounded.
Fasten Belts Chime
With ignition switch in "RUN," "BULB TEST," or "START," voltage is applied through I/P Fuse Block Fuse I/P to the Multi-Function (MFC) module
terminal A3. With the driver's safety belt unbuckled, module terminal A4 is grounded through the safety belt switch, and the FASTEN BELTS indicator
lights for 4 to 8 seconds.
The fasten belts chime sounds for 4 to 8 seconds if driver's safety belt is unbuckled and ignition switch is turned to "RUN," "BULB TEST," or
"START." If driver's safety belt is buckled when the ignition switch is turned to "RUN," "BULB TEST," or "START," there is no chime, but the
FASTEN BELTS indicator lights for 4 to 8 seconds.
Turn Signal on Chime
When a turn signal is operated, the Multi-Function Chime (MFC) module begins to monitor vehicle distance. If the turn signal is still flashing after the
vehicle has traveled 1.2km (3/4 mile), the turn signal on chime sounds.
Park Brake Chime
Refer to Brake Warning System for park brake chime operation. See: Brake Warning Indicator/Testing and Inspection
