Body Control Module Repair
Random electrical gremlins, dead locks, lights stuck on, parasitic battery drain — almost all of it traces back to the BCM. We rebuild it at component level.
The BCM controls almost every body-electrical circuit in the car: headlights, taillights, interior lights, door locks, windows, wipers, horn, and CAN gateway. When its driver ICs fail, the symptoms look random — but they almost always trace back to one or two failed output drivers or a cooked CAN transceiver.
We replace the failed components, restore the original coding, and bench-test on a CAN simulator before the unit ships back.
Common symptoms
- Random electrical gremlins that change day to day
- Door locks, windows, or wipers stop working
- Lights stuck on or won't turn on
- Parasitic battery drain overnight
- Lost CAN communication / multiple modules dropping off
- Remote / key fob stops working with no fault on the fob

FAQ
No. The original coding stays with the BCM, so your fobs continue to work without any re-programming.
Yes — a cooked output driver or stuck relay coil can pull 50–500mA continuously, draining a healthy battery overnight. Repairing the BCM is usually cheaper than chasing the drain with a meter.
