You can bypass the need for expensive dealer-specific scan tools and programming appointments, saving you significant time and money.
A Technician’s Notebook: The Case of the Haunted Tahoe
I remember a 2010 Tahoe—which uses this exact BCM—that came into my bay with a list of bizarre symptoms. The owner said his interior lights would pulse randomly, the radio would shut off, and sometimes the anti-theft system would prevent it from starting. He’d already replaced the battery and checked the main grounds. After hooking up my scanner, I saw a handful of U-codes, all pointing to communication loss with the BCM. These modules, especially on the GMT900 platform, are notorious for internal solder joint failures that cause these intermittent, ghost-in-the-machine problems. Swapping in a pre-programmed BCM like this one resolved all the issues in under an hour. It’s a common failure I’ve seen dozens of times, and this is the most direct fix.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security or anti-theft system light is illuminated, causing no-start conditions.
- ✔ Communication error codes, such as U0140, U0155, or other U-codes.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate readings on the instrument panel gauges.
- ✔ Problems with the keyless entry or remote start systems.
A Straightforward Guide to Your BCM Installation
Installing your new 2010 Escalade Body Control Module is a manageable job for a confident DIYer. On the Escalade, Tahoe, and Yukon, the BCM is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: Remove the lower dash panel beneath the steering wheel to gain access. The BCM is a black plastic box with several large multi-pin electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all the electrical connectors, ensuring each one clicks firmly into place.
- Reconnect and Test: Reattach the negative battery terminal. Turn the key to the ‘On’ position and test all body functions: lights, locks, windows, horn, etc., to confirm the repair.
Important Post-Installation Information
Because this module is central to so many systems, a couple of simple relearn procedures may be necessary after installation. This is normal and ensures all related components communicate correctly with the new BCM.
- ✔ No Core Charge: You are not required to send your old BCM back to us.
- ✔ Airbag System Sync: If the airbag (SRS) light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
- ✔ Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a professional mechanic for specific instructions for your vehicle.

Frequently Asked Questions
What does ‘programmed to my VIN’ mean?
It means we load the specific software and settings for your vehicle’s options package directly onto the module before shipping. This makes installation much simpler, as you won’t need to have it programmed at a dealership. Just provide your VIN at checkout.
Is this a difficult part to replace myself?
For someone with basic mechanical skills, it’s very manageable. The main challenge is accessing the module under the dashboard. No special tools are needed for the physical replacement, but a professional scan tool might be needed for post-install procedures like the airbag sync.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your old module or dispose of it responsibly.
Will this fix my ‘Service Theft System’ message?
A faulty BCM is a very common cause of false anti-theft system activations and ‘Service Theft System’ messages on these GM vehicles. While other issues can cause this, replacing a bad BCM often resolves the problem.
What happens if I don’t do the relearn procedures?
If the relearn procedures are needed and not performed, you may have a persistent warning light (like the airbag light) or certain features may not operate correctly. The brake pedal relearn, for example, is important for proper traction control function.
