BCM Body Control Module

BCM Diagnosis & Programming Services

Diagnosing BCM (Body Control Module) issues involves identifying problems with your vehicle's electrical system that may be related to the BCM. Your vehicle's BCM is the brain behind its electrical system, managing functions such as lighting, door locks, and entertainment features.


  • 1. Perform Component Testing: Test individual components and sensors controlled by the BCM, such as lights, door switches, or window motors, to determine if they are functioning correctly. This can help isolate the source of the problem.

  • 2. Basic Checks: Conduct basic checks, such as inspecting fuses, relays, and wiring connections associated with the BCM to ensure they are in good condition and properly connected.

  • 3. Use Diagnostic Tools: Utilize diagnostic tools, such as a scan tool or diagnostic software, to retrieve trouble codes stored in the BCM. These codes can provide valuable insights into specific issues affecting the module. You can also send us your BCM and we can run a scan for you. https://ecumaverick.com/search?q=bcm&options%5Bprefix%5D=last

  • 4. Interpret Diagnostic Codes: Interpret the diagnostic trouble codes (DTCs) retrieved from the BCM to pinpoint the root cause of the problem. Common codes related to BCM issues may indicate circuit faults, sensor failures, or communication errors.
