Before replacing your BCM, always perform a thorough check of the vehicle’s main ground connections. A corroded or loose ground wire, particularly the one located under the driver’s side A-pillar kick panel, can create resistance and mimic the exact symptoms of a faulty BCM. Ensuring your grounds are clean and tight can prevent misdiagnosis and protect your new module from damage.
Common Symptoms of a Failing BCM
- ✔ Non-functional or intermittent power windows, door locks, and interior/exterior lights.
- ✔ HVAC controls not working or blower motor stuck on one speed.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Security system errors, causing no-start conditions or random alarm activation.
- ✔ Unexplained battery drain while the vehicle is parked.
- ✔ Communication errors with other vehicle modules, leading to various diagnostic trouble codes (DTCs).
