Restore Your Truck’s Electrical System with a Plug-and-Play BCM
If your 2007-2011 GMC Yukon XL 2500 is plagued by bizarre electrical issues, you’re not alone. As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can make a reliable truck feel haunted. From flickering lights to a dead instrument cluster, the BCM is the central hub for your vehicle’s body electronics. This replacement BCM, part number 15901388, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a hassle-free, direct-fit installation.
Case Study: The Ghost in the GMC
A customer brought in a 2009 Sierra 2500 with a laundry list of intermittent problems: the radio would cut out, the dome light wouldn’t work, and the security light would flash, sometimes preventing it from starting. They’d been to two other shops that couldn’t pinpoint the fault. After connecting my scanner, I saw multiple communication loss codes (U-codes) pointing to the BCM. A quick check of the main BCM ground under the dash showed it was secure. The problem was internal to the module itself—a common failure point. Installing a VIN-programmed BCM like this one resolved all issues in under 10 minutes, saving the customer hundreds in diagnostic fees and dealership programming costs.
Is Your Truck Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ The airbag warning light is on, often with a DTC B1001 (Setup SDM Primary Key in BCM) stored.
- ✔ Power windows, door locks, or mirrors work intermittently or not at all.
- ✔ HVAC controls are unresponsive, or the blower motor behaves erratically.
- ✔ Headlights, taillights, or interior lights flicker, stay on, or won’t turn on.
- ✔ The vehicle’s security system acts up, causing no-start conditions or false alarms.
- ✔ Communication errors with other modules, leading to various warning lights on the dash.
A Straightforward Guide to Installation
One of the best features of this 2007-2011 Yukon XL 2500 BCM is its simple installation. You don’t need to be a master mechanic to get this done in your own driveway.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronics.
- Locate the BCM: On most GM trucks and SUVs of this era, the BCM is located under the driver’s side dashboard, near the steering column. It’s a black box with several large multi-pin connectors.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, the module can be unclipped or unbolted from its mounting bracket.
- Install the New BCM: Seat the new, pre-programmed module into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: lights, locks, windows, wipers, and HVAC to confirm the repair.
Post-Installation Note: In some cases, particularly if you had an airbag light, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ function to clear the light. A Brake Pedal Position Relearn may also be required. And remember, there’s no core charge, so you can keep your old part.

Frequently Asked Questions
Do I need to take my truck to the dealership for programming?
No. This module comes fully programmed to your vehicle’s specific VIN. It’s ready for installation right out of the box, saving you time and money.
Will this fix my airbag light?
It will resolve the root cause if the fault is a BCM communication error (like DTC B1001). However, after installation, you may need a bi-directional scan tool to perform the ‘SDM Key Setup’ to sync the new BCM with the airbag system and turn off the light.
Is this difficult to install for a DIYer?
Not at all. Installation typically takes less than 15 minutes with basic hand tools. The module is easily accessible under the driver’s side dashboard.
What is a core charge?
A core charge is a deposit you pay until you return your old part. We don’t require one for this BCM, so there’s no need to send your faulty module back.
What if I have issues after installation?
Our expert support team is here to help. Additionally, the part is backed by a one-year warranty for your peace of mind.
