Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Seat Belt System Circuit Description
The seat belt indicator will illuminate when the following conditions occur simultaneously:
- The ignition switch is in one of the following positions:
- RUN
- BULB TEST
- START
- The LF seat belt is not fastened.
The audio alarm, located within the body control module (BCM), also incorporates an indicator within the instrument panel cluster (IPC). The seat belt indicator works in conjunction with the audio alarm. When the BCM receives a signal that the LF seat belt is unfastened, the BCM sends a signal to the IPC to command ON the seat belt indicator.
