The body control module (BCM) controls the audible warnings system. The audible warnings system sounds a chime in order to bring attention to one of the following conditions:
| • | The check gauges indicator is ON. |
| • | The seat belt is not fastened. |
| • | The key is in the ignition cylinder and the door is open. |
| • | The headlamps are ON and the door is open. |
| • | The turn signal is ON continuously for a distance of 1.2 km (0.75 mi). |
| • | The park brake is engaged under one of the following conditions: |
| - | The vehicle is moving faster than 5 km/h (3 mph). |
| - | The vehicle is in gear longer than 8 seconds. |
Chime Timing
The BCM produces an audible chime for certain error states. Refer to the table below for the chimes and the repetition rates.
Function | Repetition Rate | Power Mode |
|---|---|---|
Check Gauges | 300/minute | RUN |
Seatbelt Not Fastened | 50/minute | RUN |
Key in Ignition Switch | Note 1 | OFF, ACCY |
Headlamps ON | 300/minute | OFF, ACCY |
Turn Signal ON | Note 2 with continuous operation after 1.2 km (0.75 mi) | RUN |
Park Brake Warning | 300/minute with continuous operation of greater than 5 km/h (3 mph) or vehicle in gear longer than 8 seconds | RUN |
Note 1 is a repetition 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. | ||
Key-in Ignition Chime
Voltage is applied at all times through the INT LAMP fuse and CKT 340 to the BCM. When the key is in the ignition switch and the left front door is open, CKT 80 and CKT 394 are grounded. When the BCM senses the concurrent grounding of the circuits, the BCM sounds the key-in ignition chime.
Fasten Belts Chime
When the ignition switch is turned to the RUN or the START position, voltage is applied through the A/C BFC fuse to CKT 439. When the left front seatbelt is unbuckled, CKT 238 grounds through the seatbelt switch. The fasten belts chime sounds for 8 seconds.
Lights-on Chime
The BCM sounds the lights-on chime under the three following conditions:
- Battery voltage on CKT 9 indicates that the park lamps or the headlamps are ON.
- Zero volts from the IPC/BFC ACC fuse (CKT 1600) indicates that the ignition switch is not in any of the following positions:
- A ground on CKT 394 indicates that the left door is open.
| • | OFF/LOCK |
| • | ACCY |
| • | RUN |
| • | START |
Turn-Signal-on Chime
When operating a turn signal, voltage is applied to the BCM connector C2 terminal A8. The BCM begins to monitor vehicle distance on input from the vehicle speed sensor (VSS). If the turn signal is still flashing after the vehicle travels 1.2 km (0.75 mi), the turn signal chime will sound as the turn signal flashes.
Check Gauges Chime
The check gauges chime sounds 3 notes every time one of the following indicators turns ON and the engine has been running for more than 5 seconds.
| • | Low Oil Pressure |
| • | High Temperature |
| • | Low Fuel Level |
| • | Brake Indicator via Serial Data Command |
| • | ABS |
| • | Service Vehicle Soon |
| • | Check Oil Level |
| • | Volts |
| • | Low Washer Fluid |
| • | Low Coolant Level |
The check gauges chime sounds 3 tones at a rate of 300 tones per minute. The check gauges chime is not limited to once per ignition cycle for the door ajar indicator when the transaxle is in DRIVE or REVERSE. The chime sounds whenever the activating conditions occur throughout an ignition cycle.
Park Brake Chime
The park brake chime sounds under the following conditions:
| • | The vehicle speed is greater than 5 km/h (8 mph). |
| • | The park brake is set. |
| • | An eight second timer has not expired. |
The chime deactivates under the following conditions:
| • | The vehicle speed falls below 5 km/h (8 mph) and the eight second timer expires. |
| • | The park brake is released. |
