End the Electrical Gremlins in Your GM Truck or SUV
If you’re dealing with a frustrating array of electrical problems in your 2007-2011 Cadillac Escalade, the Body Control Module (BCM) is the most likely culprit. As the central command center for your vehicle’s body electronics, a failing BCM can cause chaos, from flickering lights to a no-start condition. This OEM-quality replacement, part number 15284816, comes fully programmed to your vehicle’s specific VIN. This eliminates the need for expensive dealership programming, allowing for a straightforward, plug-and-play installation that gets you back on the road with confidence.
Case Study: A Tricky Diagnosis
I once had a 2010 Escalade in the shop with a bizarre collection of issues. The customer reported intermittent radio failure, the driver’s side window wouldn’t go down, and the airbag light was on. His previous mechanic had replaced the radio and the window switch, with no success. After scanning the vehicle, I found communication codes across multiple systems, all pointing back to the BCM. The internal circuitry had failed, disrupting the entire data network. Installing a new, VIN-programmed 2007-2011 Escalade Body Control Module resolved all three problems at once. It’s a classic example of how one single component can create multiple, seemingly unrelated symptoms.
Is Your Escalade Showing These Symptoms?
- ✔ The security light is flashing and the vehicle won’t start or stalls intermittently.
- ✔ Power windows, door locks, or interior lights work sporadically or not at all.
- ✔ The HVAC blower motor is dead, or the climate controls are unresponsive.
- ✔ You have an active airbag light, often with a DTC B1001 (Setup SDM Primary Key in BCM) code stored.
- ✔ Wipers operate on their own or won’t turn off.
- ✔ A host of communication (U-codes) or body-related (B-codes) diagnostic trouble codes are present.
A Straightforward Guide to Installation
For most DIYers and professional technicians, this is a quick and simple job. The BCM is typically located under the driver’s side dashboard, near the steering column.
- Safety First: Always disconnect the negative battery terminal and wait a few minutes before starting work.
- Locate the BCM: On your Escalade, find the module under the dash. It will have several large electrical connectors attached to it.
- Disconnect and Remove: Carefully unclip all electrical harnesses. Then, release the mounting tabs or bolts holding the old BCM in place and remove it.
- Install the New Module: Seat the new BCM into the mounting bracket and securely reconnect all electrical harnesses. You’ll hear a click as they lock in place.
- Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all functions—lights, windows, locks, wipers, and HVAC—to confirm the repair was successful.
Post-Installation Note: In some cases, particularly if the airbag light was on, you may need to perform a ‘Setup SDM Primary Key’ procedure using a professional-grade scan tool. This syncs the new BCM with the airbag system. A brake pedal position relearn may also be required on certain models.

Do I need to have this BCM programmed by the dealer?
Do I need to have this BCM programmed by the dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. It arrives ready for plug-and-play installation, saving you time and the high cost of dealership programming.
Is this a difficult part to replace myself?
Not at all. The physical replacement typically takes less than 15 minutes with basic hand tools. It’s located under the driver’s side dash and is easily accessible.
What is a core charge?
A core charge is a deposit that is refunded when you send back your old part. We do not have a core charge on this module, so you can keep your old part without any hassle.
Will this fix my airbag light?
If the airbag light is caused by a BCM communication error (like DTC B1001), this module will resolve the root cause. However, you may need a capable scan tool to perform the ‘Setup SDM Primary Key’ function after installation to clear the light.
What is the warranty on this part?
This Body Control Module is backed by our one-year, hassle-free warranty, giving you peace of mind with your purchase.
