Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating and unpredictable electrical problems in your 2010 Chevy Suburban 1500? Issues like flickering interior or exterior lights, power windows and locks operating on their own, or a security system that prevents your truck from starting are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing symptoms. This isn’t just an annoyance; it’s a matter of reliability and safety. We offer a direct, dependable solution: a replacement Body Control Module, part number 25847589, delivered to your door fully programmed to your vehicle’s specific VIN.
A Technician’s Notebook
A customer brought in their 2010 Suburban 1500 last month with a list of gremlins that sounded like a haunted truck. The dome lights would stay on, the radio would randomly shut off, and worst of all, the anti-theft light was on, causing an intermittent no-start condition. They had already replaced the battery and checked the grounds. After connecting my scan tool, I saw multiple communication loss codes with various modules. This immediately pointed me to the BCM. In my 20+ years of experience, I’ve seen that water intrusion from a leaky windshield seal is a common culprit for BCM failure in these SUVs, as the module is located under the steering column. A new, properly programmed module like this one resolved all their issues in one go, saving them from chasing electrical ghosts.

Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ Horn honking unexpectedly or failing to work.
- ✔ Security system light illuminated on the dash, often causing a no-start condition.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Communication error codes with other vehicle modules when scanned.
- ✔ Inconsistent A/C and heater fan speed operation.
A Straightforward Guide to Installation
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. Wait a few minutes for the system capacitors to discharge.
- Locate the BCM: On the 2010 Suburban 1500, the Body Control Module is typically located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the multiple wiring harness connectors from the old BCM. They have locking tabs that need to 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. Securely plug in all the wiring harnesses, ensuring each connector clicks firmly into place.
- Reconnect Power: Re-attach the negative battery terminal and tighten it securely.
Important Final Steps After Installation
To ensure all systems operate correctly with your new 2010 Suburban 1500 BCM, a few final procedures are necessary. These steps synchronize the new module with your vehicle’s other critical systems.
- Airbag System Reset: The SRS/airbag warning light will likely be on after the swap. You must perform the ‘Setup SDM Primary Key in BCM’ procedure using a compatible bi-directional scan tool. This is a critical safety step to ensure the airbag system is fully functional.
- Brake Pedal Position Sensor Relearn: Some vehicles require a recalibration of the brake pedal position sensor. This ensures the brake lights and stability control system function correctly. This procedure can also be performed with a capable diagnostic tool.
- Theft Deterrent Relearn: Your vehicle may require a key relearn procedure, which can typically be done without a scan tool. The common method is to turn the key to the ‘ON’ position for 10 minutes, off for 10 seconds, and repeat this cycle three times.
Note: If you are not comfortable performing these relearn procedures, a local automotive shop can complete them for you quickly.

Frequently Asked Questions
What exactly does this Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and more, ensuring everything works together as it should.
Is this a simple plug-and-play installation?
Because we program the module to your VIN before shipping, the physical installation is plug-and-play. However, as noted above, you will need to perform a few simple electronic ‘relearn’ procedures for the theft-deterrent and airbag systems to fully integrate the module.
How do I provide you with my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Will this fix my ‘Service StabiliTrak’ message?
While a faulty BCM can contribute to StabiliTrak issues, that message can be caused by many different components, such as wheel speed sensors or the steering angle sensor. A proper diagnosis is recommended, but if you have other BCM-related symptoms, this is a likely solution.
What happens if I don’t do the ‘Setup SDM Primary Key’ procedure?
The airbag warning light will remain on, and more importantly, the airbag system may not function correctly in the event of a collision. This is a mandatory safety procedure that must be completed after installation.
Do I need to send my old BCM back to you?
No, there is no core charge or need to return your original module. You can dispose of it responsibly once the new one is installed and working.
