Restore Full Functionality to Your Cadillac SRX
Are you battling bizarre electrical issues in your 2007-2009 Cadillac SRX? Flickering lights, malfunctioning power windows or locks, a radio that has a mind of its own, or even a frustrating no-start condition can all point to one culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s comfort and convenience features, a faulty BCM can turn your luxury SUV into a source of daily frustration. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
This is a direct-fit replacement Body Control Module, part number 15299986, which arrives at your door ready for installation. We take the hassle and high cost out of the repair process with our professional Cloning Service. Simply provide us with your vehicle’s VIN after purchase, and our technicians will program the module with the latest GM software specific to your SRX. This means you can bypass the expensive trip to the dealership for programming, saving you time and money.
A Technician’s Notebook: The BCM Diagnosis
I remember a 2008 SRX that came into the shop with a laundry list of complaints from the owner: the dome light wouldn’t turn off, the driver’s side window worked intermittently, and the key fob would only lock the doors sometimes. A scan tool showed a dozen communication codes (U-codes) pointing to the BCM. After confirming power and ground to the module were solid, it was clear the BCM’s internal logic had failed—a common issue often caused by voltage spikes or moisture exposure over time. Replacing the module with a pre-programmed unit like this one resolved all issues in under an hour, a far cry from the multi-day affair it could be if you’re waiting on a dealership.
Is Your SRX Showing These Symptoms?
A failing BCM can cause a wide range of problems. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ Malfunctioning radio, climate control, or instrument cluster gauges.
- ✔ Key fob not responding or working intermittently.
- ✔ “Service Theft System” or other warning messages on the dash.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- ✔ The vehicle fails to start, even with a good battery and starter.
Your Straightforward BCM Installation Guide
Installing your new 2007-2009 SRX BCM is a manageable job for a confident DIYer. For the SRX, the BCM is typically located on the left (driver’s) side of the dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to discharge.
- Access the Module: You will likely need to remove the lower dash panel beneath the steering column to gain access to the BCM. It’s usually a black box with several large multi-pin electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New BCM: Mount the new, pre-programmed BCM in the same location and reconnect all electrical connectors securely.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: windows, locks, lights, radio, etc., to confirm the repair.
Important Post-Installation Steps
Because this module is pre-programmed, most functions should work immediately. However, depending on your vehicle’s specific configuration, a couple of final sync procedures might be necessary:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and stability control operation. This also typically requires a capable scan tool.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. Our Cloning Service means the module arrives pre-programmed to your vehicle’s VIN. This allows you to install it yourself or have your local mechanic do it without needing specialized GM programming tools.
What is a ‘Cloning Service’?
This service involves transferring your vehicle’s specific configuration data (from the VIN you provide) onto the replacement BCM. This ensures all the options and features your car came with from the factory work correctly with the new module.
Where is the BCM located on my 2007-2009 Cadillac SRX?
On the 2007-2009 SRX, the Body Control Module is typically found behind the lower dashboard trim panel on the driver’s side, near the steering column.
What happens to my old BCM? Is there a core charge?
There is no core charge for this item. Our service includes returning your original module to you along with the programmed replacement unit. We do not keep your original part.
Will this fix my car’s no-start problem?
If the no-start condition is caused by the BCM not recognizing the key or failing to activate the proper relays (a common BCM failure), then yes, this part should resolve the issue. However, no-start problems can have many causes, so a proper diagnosis is always recommended.
