Warning Chimes

The Audio Alarm System brings the driver's attention to one or more of several conditions: 1) lights are on and Ignition Switch is set to LOCK, OFF or ACCY; 2) ignition key is in Ignition Switch and is set to LOCK, OFF, or ACCY, and driver's door is open; and 3) safety belt is unbuckled and Ignition Switch is in RUN, BULB TEST, or START. The Multi-Function Chime (MFC) Module is also used as the audible alarm for the Driver Information Center (DIC).
Voltage is applied at all times through I/P Fuse Block Fuse 11 to terminal A1 of the Multi-Function Chime (MFC) Module to power the Module. Voltage is also applied from the Light Control Module to terminal A5 of the Multi-Function Chime (MFC) Module with the Park Lights on.
With the Ignition Switch in RUN, BULB TEST, or START, voltage is applied through I/P Fuse Block Fuse 6 to terminal A3 of the Module.

Lights On Chime

If the LH front door is open and the Multi-Function Chime (MFC) Module does not sense voltage at the Lights Off Input (terminal A5) and no voltage at the Ignition On Input (terminal A3), the fast-pulsed Lights 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 6 to the Multi-Function Chime (MFC) Module at terminal A3. With the driver's safety belt unbuckled, terminal A4 of the Module 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 will light for 4 to 8 seconds.
