Restore Your Vehicle’s Electrical Stability
Are you chasing down frustrating electrical gremlins in your 2010 Cadillac Escalade or another GM vehicle? Seemingly random issues like flickering lights, malfunctioning power windows or locks, a security system that acts up, or even a no-start condition can often be traced back to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it starts to fail, it can create a cascade of confusing and unpredictable problems.
This isn’t just an inconvenience; it can be a major headache. A trip to the dealership often means high diagnostic fees, expensive parts, and additional charges for programming. We offer a smarter, more direct solution. This replacement Body Control Module, part number 15828601, arrives at your door pre-programmed with the latest GM software, specifically matched to your vehicle’s VIN. This eliminates the need for a dealer visit for programming, saving you significant time and money.
From the Diagnostic Bay: The Case of the Spooked Escalade
A customer brought in a 2010 Escalade with a list of complaints that sounded like the vehicle was haunted. The radio would change stations on its own, the interior lights would pulse dimly at night, and occasionally, the vehicle wouldn’t recognize the key fob. Scanning the vehicle, I found a dozen communication codes (U-codes) pointing to intermittent network loss. In my 20+ years as a tech, I’ve seen this pattern hundreds of times. While other modules were flagged, the root cause was a failing BCM corrupting the data bus. We installed a VIN-programmed BCM, and every single ghost in the machine vanished. This is a classic BCM failure scenario.
Key Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty Body Control Module could be the cause. A professional diagnosis is always recommended, but these are strong indicators:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ The instrument cluster displaying false warnings or acting erratically.
- ✔ Communication Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other U-series codes.
- ✔ A parasitic battery drain that you can’t trace to any other source.
Your Straightforward BCM Installation Guide
Installing your new 2010 Escalade Body Control Module is a manageable job for a confident DIYer or any professional technician. Since we handle the programming, the physical swap is the main task.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow the system’s capacitors to discharge.
- Locate the BCM: On most compatible SUVs and trucks like the Escalade, Tahoe, and Yukon, the BCM is located under the driver’s side of the dashboard, near the steering column. On vans and some sedans, it may be in the center dash area. Consult a service manual for your specific model’s location.
- Remove Trim Panels: You will likely need to remove the lower dash panel or knee bolster to gain access to the module. These are typically held in by a few screws and clips.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and reconnect all the electrical harnesses. Ensure they click securely into place.
- Post-Installation Steps: Reinstall any trim panels you removed and reconnect the battery terminal. Start the vehicle and test all functions (lights, locks, windows, etc.). Note that some vehicles may require additional relearn procedures as outlined below.
Important Post-Installation Information
While this BCM is programmed for your vehicle, some integrated systems may require a handshake procedure after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the correct software and vehicle-specific options from GM. This ensures the module works correctly right out of the box, saving you a trip to the dealer.
Is this a plug-and-play part?
Yes, because we program it to your VIN, it is designed to be plug-and-play. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which may require a scan tool.
Do I have to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this fix a parasitic battery drain?
A failing BCM is a very common cause of parasitic battery drain because it may not be allowing the vehicle’s networks to go to ‘sleep’ after you turn it off. While other causes are possible, replacing a faulty BCM often solves this issue.
What if my part number isn’t listed but my vehicle is?
Please contact us with your VIN and original part number. GM often supersedes part numbers, and we can verify compatibility to ensure you receive the correct component for your vehicle.
