Is Your Cadillac SRX, Chevy Cruze, or GMC Terrain Plagued by Bizarre Electrical Problems?
If you’re dealing with flickering lights, malfunctioning power windows, a security system that acts on its own, or a dashboard that lights up with random warnings, the culprit is likely a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can create a cascade of frustrating and unpredictable issues. Finding a solution can be daunting, often involving expensive dealership visits, programming fees, and vehicle downtime. But there is a better way.
We offer a straightforward, plug-and-play solution for your vehicle. This listing is for a replacement BCM, part number 13578420, that is professionally programmed using the data from your original module. This data transfer service ensures that the replacement unit is a perfect match for your vehicle’s specific configuration, retaining all original keys and settings. The result is a seamless installation without the need for a trip to the dealer for costly programming.
Common Symptoms of a Failing BCM
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your Body Control Module needs attention:
- ✔ Intermittent or non-functional power windows, door locks, and interior lights.
- ✔ The security system or alarm randomly activates.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Dashboard warning lights (like ABS, Airbag, or Traction Control) appearing without a clear cause.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ Key fobs not being recognized or working inconsistently.
- ✔ A parasitic battery drain that leaves you with a dead battery.
- ✔ Complete failure to start, even with a good battery and starter.
From the Diagnostic Bay
We had a 2010 Cadillac SRX come into the shop with a classic ‘haunted car’ complaint. The owner said the interior lights would flicker at night, the radio would sometimes change stations on its own, and twice he’d come out to a dead battery. He’d already replaced the battery and alternator with no luck. After running diagnostics, we traced the issue to a parasitic draw originating from the BCM. The module wasn’t properly going to ‘sleep’ when the car was off, slowly draining the battery. By providing a replacement BCM with his original data transferred, we solved all the ghostly electrical issues in one go. The customer was thrilled to have his car back to normal without a massive dealership bill.

Installation for Your 2010 SRX Body Control Module
Once you receive the programmed module, installation is straightforward. Because we’ve transferred your vehicle’s original data, this unit is plug-and-play. Simply disconnect the battery, locate and remove your old BCM (typically found in the LH dash or kick panel area), and install the replacement. Reconnect the battery, and you’re ready to go.
Important Post-Installation Notes:
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a quick sync or relearn procedure after the BCM is replaced. These are simple procedures for any qualified technician with a professional scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control function.
Always consult a factory service manual or a qualified technician for specific guidance related to your vehicle.
