Before you begin the installation, always disconnect the negative terminal of your vehicle’s battery. This crucial step prevents the risk of electrical shorts to the new module or other components. It also helps the vehicle’s systems perform a hard reset, which can clear out residual fault codes and ensure a smoother integration of the new BCM upon reconnection.
Symptoms of a Failing Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Unresponsive or intermittent power windows, door locks, or interior/exterior lights.
- ✔ HVAC system malfunctions, such as a blower motor that won’t turn on or stays stuck on one speed.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Vehicle security system acting up, leading to false alarms or preventing the engine from starting.
- ✔ Strange instrument cluster behavior or multiple warning lights with no other apparent cause.
- ✔ Communication errors with other modules when checked with a diagnostic scanner.
