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.
Body Control Module (BCM)
| Refer to COMPONENT INDEX . |
The BCM performs the gateway function from the CAN-IHS to the CAN-Chassis (CAN-C) network. The BCM receives BSM warning messages from the LBSS and will gate the signal and forward it to the IPC for display. The BCM also receives the request to mute that audio which it gates to the Radio, or if equipped, to the AMP. If equipped with an AMP, a chime will sound.
The BCM also provides fuse protected power to the LBSS and RBSS.
