Restore Full Electronic Function to Your GM Vehicle
Are you battling frustrating electrical gremlins in your car, truck, or SUV? Issues like flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a vehicle that refuses to start can often be traced back to a single component: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause a wide range of confusing and intermittent problems. This replacement BCM, part number 15837419, is the definitive solution to get your vehicle back in perfect working order.
Symptoms of a Failing Body Control Module
If you’re experiencing any of the following, a faulty BCM is the likely culprit:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Malfunctioning security system or anti-theft light staying on.
- ✔ Remote keyless entry (key fob) failing to operate.
- ✔ Wipers or radio turning on and off randomly.
- ✔ False warning lights on the instrument cluster.
- ✔ A no-start condition where the engine cranks but won’t fire up.
Why Choose Our Programmed GM BCM?
The biggest hurdle in replacing a BCM is the need for expensive, dealer-specific programming. Our solution eliminates that step entirely. When you purchase this module, we will flash it with the latest GM software updates using your vehicle’s specific Vehicle Identification Number (VIN). This means the part arrives at your door ready for a true plug-and-play installation. No trips to the dealer, no extra programming fees, and no core charge—you can keep your old part. This is the most efficient and cost-effective way to fix your vehicle’s BCM issues.
Important Post-Installation Information
While our Programmed GM BCM is designed for a simple installation, some vehicle systems may require a relearn procedure to sync with the new module. This is a normal part of the process.
- Airbag System (SRS): If your airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ will be necessary. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position: On some models, a ‘Brake Pedal Position Sensor Relearn’ may be needed to ensure your brake lights and traction control system function as intended.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that acts as a central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security systems, and the radio.
