Circuit Description

The body control module (BCM) controls the operation of the seat belt indicator. The seat belt indicator is located in the instrument panel cluster (IPC). The BCM turns the seat belt indicator ON by sending voltage through the seat belt indicator supply voltage circuit. The seat belt indicator receives ground through the seat belt indicator ground circuit.

The BCM turns the seat belt indicator ON for 55 seconds when the following conditions are met:

• The ignition is ON.
• The driver unbuckles the seat belt.

If the driver seat belt is fastened during the 55 seconds period, the BCM turns the seat belt indicator OFF. If the driver's seat belt releases anytime during the same ignition cycle, the BCM turns the seat belt indicator ON again for 55 seconds.
