For 1990-2009 cars

### Warning/Reminder Chimes

The body control module (BCM) sounds a chime in order to bring attention to one or more of the following conditions:

• | The lights are on and the ignition switch is not in the RUN, BULB TEST, or START positions.

• | The ignition key is in the ignition switch when the driver's door is open.

• | The seatbelt is unbuckled when the ignition switch is placed into the RUN, BULB TEST or START position.

• | The turn signal has been on for more than a half mile. Voltage is applied at all times through the fuse block in order to power the solid state BCM.

#### Ignition Key Warning

A ground is provided to the BCM, which sounds the chime, when both of the following conditions exist:

• | The key is in the ignition switch.

• | The driver's door is open.

#### Fasten Seatbelt Warning

Voltage is applied through the fuse block to the BCM when the ignition switch is in one of the following positions:

• | RUN

• | BULB TEST

• | START

With the driver's seat belt unbuckled, the module is grounded through the seatbelt switch. This causes the chime to sound. When the driver's seatbelt is buckled, the alarm shuts off. If the driver's seatbelt remains unbuckled, the alarm times out after 4 to 8 seconds.

#### Lights-On Warning

Voltage is applied to the audio alarm module when the headlamp switch is in the HEAD or PARK position. Voltage is applied through the fuse block to the alarm module when the ignition switch is in one of the following position:

• | RUN

• | BULB TEST

• | START

These 2 voltages are sensed and the alarm is not sounded.

The module loses voltage when the ignition switch is not in one of the following positions:

• | RUN

• | BULB TEST

• | START

The audio alarm module senses change. If voltage is still available, the voltage is applied in order to sound the alarm. The alarm can be turned off by turning the headlamp switch to the OFF position. The alarm module will no longer sense voltage from the headlamp switch, so the alarm will not sound.
