Restore Your Vehicle’s Electrical System with a VIN-Programmed BCM
Are you battling frustrating and unpredictable electrical problems in your GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a car that won’t start can often be traced back to a single component: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it fails, it can create a cascade of confusing and seemingly unrelated symptoms. This replacement Body Control Module, compatible with part number 15828601 and many others, is the reliable solution to get your vehicle back in perfect working order.
From the Diagnostic Bay
We once had a 2010 Chevy Impala in the shop with a list of complaints that seemed endless. The dome lights would stay on, the driver’s side window wouldn’t go down, and the remote key fob worked only intermittently. The owner had already replaced the battery and checked fuses with no luck. After connecting our diagnostic tool, we saw multiple communication errors all pointing to the BCM. Instead of a complex and costly wiring chase, we installed a VIN-programmed BCM. In under an hour, every single one of the ghost-like electrical issues was resolved. It’s a perfect example of how this one module can be the root of so many problems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Vehicle security system faults or alarm sounding unexpectedly.
- ✔ Wipers or horn activating on their own or not at all.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ No-start or intermittent starting conditions due to security system communication failure.
- ✔ “Service Stability System” or other warning messages on the dash.
Why Choose Our Programmed GM BCM?
This isn’t just a generic, off-the-shelf part. We take the guesswork out of the repair by pre-programming the module specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) during checkout, and our technicians will flash the BCM with the latest, most stable software direct from GM. This ensures the module communicates perfectly with your vehicle’s other computers, restoring original functionality and performance. This service saves you a trip to the dealership and eliminates the need for expensive programming tools.
Installation and Post-Install Notes
While this module is designed for a straightforward installation, some vehicles may require additional steps after the BCM is connected. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct operation of the brake lights and stability control systems.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer that acts as the central hub for your vehicle’s body electronics. It controls functions not related to the engine, such as power windows, locks, lights, wipers, the security system, and instrument cluster gauges.
Why do you need my VIN?
Your VIN is essential because it allows us to program the BCM with the exact software and settings for your vehicle’s specific options and features. This ensures a seamless integration and proper function, saving you a costly trip to the dealership for programming.
Is this part truly plug-and-play?
For most vehicles, yes. Because we pre-program it to your VIN, the primary installation is plug-and-play. However, as noted, some models may require a simple relearn procedure for the airbag or brake pedal position sensor, which may require a professional scan tool.
Will this fix my car’s specific electrical problem?
If your vehicle is exhibiting multiple symptoms listed above, a faulty BCM is a very likely cause. A proper diagnosis from a qualified mechanic is the best way to be certain, but replacing a known-bad BCM with our Programmed GM BCM is a direct and effective repair.
Does this module replace other part numbers?
Yes, this BCM is a direct replacement for a long list of original GM part numbers, including 10382479, 15872388, 20815898, 22860591, and many more. Please check the fitment list to confirm compatibility.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module without needing to send it back.
