Programmed 2007-2009 SRX Body Control Module 20864768 | VIN-Matched

End the Electrical Headaches in Your Cadillac SRX

If you’re dealing with baffling electrical issues in your 2007-2009 Cadillac SRX—like power windows with a mind of their own, flickering dash lights, a security system that won’t cooperate, or even a no-start condition—you’ve likely met the culprit: a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, when the BCM falters, it can create a cascade of frustrating and seemingly unrelated problems. In my 20+ years of diagnostics, I’ve seen these modules cause more strange symptoms than almost any other component. Water intrusion and voltage spikes are common culprits that damage the sensitive internal circuits.

This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and high cost of dealership visits out of the equation. Simply provide your vehicle’s VIN during checkout, and my team will program this BCM with the latest GM-certified software specifically for your SRX. This ensures all factory-intended functions operate correctly right out of the box, restoring the reliability and performance you expect from your Cadillac.

Common Signs of a Failing GM BCM

A faulty BCM can manifest in numerous ways. If your vehicle is experiencing any of the following, a failing module is a likely cause:

• ✔ Erratic or non-functional power windows, door locks, or mirrors.
• ✔ Interior or exterior lights staying on or not working at all.
• ✔ The security system or keyless entry malfunctioning.
• ✔ Warning lights for ABS, Airbags, or Traction Control appearing on the dash.
• ✔ Communication error codes, particularly U-codes like U0140, U0155, or U0164.
• ✔ The engine cranks but refuses to start due to a security system fault.
• ✔ A/C and climate control systems behaving unpredictably.

A Straightforward Guide to BCM Installation

Installing your new BCM is a manageable job for a confident DIYer or any professional mechanic. For the 2007-2009 SRX, the BCM is located on the left-hand (driver’s) side of the dash.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down completely.
2. Locate the BCM: On the SRX, you’ll typically find the BCM mounted to the left of the steering column, often behind a lower dash panel. You may need to remove this trim panel for access.
3. Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
4. Install the New Module: Mount your new, pre-programmed BCM in the exact same position as the old one. Securely reconnect all electrical connectors, ensuring they click into place.
5. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: lights, windows, locks, etc.

Important Post-Installation Notes

While our VIN programming handles the majority of the setup, some vehicles may require additional steps for full system integration:

• Airbag System Sync: If the airbag 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 certain models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
• No Core Charge: You can keep your old module, as there is no core charge or need to return it.

Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult a qualified professional if you are unsure about any step.
