The Check Gauges Chime will sound three tones at a rate of
300 tones per minute and is not limited to once per ignition cycle for the Door Ajar
Indicator when the transaxle is in Drive or Reverse. The chime will sound whenever the activating conditions occur throughout an ignition cycle.
Chime Timing
Table #1 Chime Description
The Body Function Controller
(BFC) produces an audible chime for certain error states. The chimes and their repetition rates are found in Table #1
shown above.
Note 1 is a reception rate of
150/minute for 3 seconds then 18/minute at the 50/minute decay rate. Note 2 is synchronized with the turn signal flash
rate. The chime is synchronized with the leading edge of the Turn Signal, but decays as the Turn Signal rate changes.
Fasten Belts Chime
With the Ignition Switch turned to the RUN or START positions voltage is applied through the A/C BFC Fuse to the 439 circuit. With the LH Front Seat
Belt unbuckled, circuit 238 is grounded through the Seat Belt Switch. The Fasten Belts Chime sounds for
8 seconds.
General Informations
The Audible Warnings System is controlled by the Body Function Controller
(BFC) and sounds a chime to bring attention to several conditions. These
conditions are:
^
Check Gauges Indicator is ON.
^
Seat Belt is not fastened.
^
Key is in the ignition Cylinder (with door open).
^
Headlamps are ON (with door open).
^

1.2 km [3/4 mile]).
^
Park Brake engaged (with continuous operation of greater than
5 km/h [3 mph] or vehicle in gear longer than 8 seconds).
Key-In Ignition Chime
Voltage is applied at all times through the INT LAMP Fuse and circuit 340 to the Body Function Controller
(BFC). When the key is in the Ignition
Switch and LH front door is open circuits 80 and 394 are grounded. When the BFC senses the concurrent grounding of these circuits the BFC sounds the
Key In Ignition Chime.
Lamps-ON Chime
The Body Function Controller
(BFC) sounds the Lights-On Chime when the following three conditions are met:
