Does the BCM control the headlights?
What Does A Body Control Module Do? The body control module connects door locks, headlights and windshield wipers. It links many electronic vehicle features together and keeps them under central surveillance so that your automobile can operate them easily.
What’s the difference between a BCM and an ECM?
The body control module (BCM) monitors the signal circuit of the cruise control switches. The BCM relays the cruise control switch status to the engine control module (ECM) via the GMLAN serial data circuit. The ECM uses the status of the cruise control switch to determine when to capture and maintain the vehicle speed.
What happens if your BCM is not working?
A malfunctioning BCM will activate dashboard instrumentation cluster error and warning lights. These lights may flash off and on if the BCM is not able to read the sensors correctly. Your vehicle performance may also be affected as the BCM communicates with other control modules in the vehicle.
When to replace a Body Control Module ( BCM )?
Because the BCM is the one handling a lot of different functions in the car, it is also inevitable for all those functions to stop working when the BCM does get damaged. When this happens, a replacement may be the best resort for you. Still, the repair cost of the control module also depends on the kind of vehicle that you drive.

Why is the LH low beam not working?
A. FYI the BCM has independent fault-finding logic circuits for the LH vs RH low beam – given your RH-only problem, IF the failure is in the BCM it would follow that logic circuit is what’s failed ‘open’ for the RH low-beam side.
