Chime System
1996 Chrysler LHS V6-215 3.5L SOHCSECTION Chime System
DESCRIPTION
The chime system is comprised of an audible chime located internal to the BCM, and is dependent on various inputs to the BCM to operate. These inputs include key-in ignition switch, exterior lamps, seat belt switch, and speed warning (middle east vehicles only).
CIRCUIT OPERATION
Seat Belt Warning
The seat belt chime is used to indicate to the operator that the seat belt is not fastened when the ignition switch is in the RUN position. The seat belt switch is normally CLOSED with the seat belt buckled. Circuit G10 is connected between the Body Control Module (BCM) and the switch. Ground for the switch is provided on circuit Z1. The Z1 circuit terminates at the body ground located at the left kick panel.
Exterior Lamp-on Warning
The exterior lamp ON chime is used to indicate to the operator that the lamps are ON with the drivers door OPEN and the key removed from the ignition. The Body Control Module (BCM) uses information from circuit L7 to determine if the lamps are ON, and circuit G75 for drivers door ajar. The chime function will not operate when the headlamp delay feature is active.
Key-In Ignition Warning
The Key-In chime is used to indicate to the operator that the key is in the ignition with the driver's door OPEN. If the key is in the ignition, a ground path is completed from the G26 circuit at the Body Control Module (BCM), through the CLOSED switch, to the Z1 circuit. The Z1 circuit is the ground circuit and terminates at the body ground located at the left kick panel.
When the driver's door is open the normally OPEN door ajar switch CLOSES completing a path to ground on circuit G75. The BCM processes this information and turns on the chime.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
