2007 – 2012 GMC Acadia Body Control Module (BCM) 20815898 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Imagine you’re loading up your 2007-2012 GMC Acadia for a family road trip, but suddenly the power locks fail, headlights flicker erratically, or the dashboard lights up with unexplained warning codes. Frustrating, right? Questions like “why won’t my GMC Acadia windows work intermittently?” or “how to resolve BCM-related DTC codes in a 2007 Acadia?” often point to a faulty Body Control Module. This pre-programmed BCM, part number 20815898, is your direct solution, flashed with the latest GM updates using your VIN for seamless compatibility. It clears persistent DTC codes, restores electrical stability, and improves overall vehicle reliability—essential for those long drives or daily commutes. Drawing from over two decades in diagnostics, I’ve seen these issues stem from water intrusion or voltage spikes, leading to costly downtime. This module not only fixes them but enhances features like remote start responsiveness, based on real shop scenarios where a simple swap prevented repeat failures.

Common Issues & How This Fixes Them
In my experience troubleshooting 2007-2012 GMC Acadias, a failing BCM often manifests as erratic power windows that roll down but not up, caused by internal circuit degradation from heat or moisture—common in humid climates. This can trigger DTC codes like P069E, disrupting daily use and safety. Another frequent problem is intermittent interior lighting or door lock failures, stemming from corrupted software, which I’ve fixed in shop scenarios by replacing with updated modules to restore communication between systems. Dashboard warnings, such as unexplained airbag lights, arise from mismatched calibrations, potentially compromising crash protection. This pre-programmed BCM addresses these by resetting protocols and integrating fresh GM flashes, effectively clearing codes and preventing recurrence. For instance, one client with a high-mileage Acadia saw towing issues vanish post-install, as the module stabilized voltage for trailer lights. It also tackles remote key fob inconsistencies, often linked to signal interference, by optimizing antenna controls—going beyond basic fixes to ensure long-term dependability.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates tailored to your 2007-2012 Acadia.
- Disconnect the battery to ensure safety and prevent electrical surges during the swap—locate the BCM on the left-hand dash side.
- Remove the old module by unplugging connectors and unscrewing mounts; compare with the new one to confirm fit.
- Install the new BCM, reconnect all wiring securely, and reconnect the battery.
- Perform post-install procedures: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light, and check if brake pedal recalibration is needed for optimal braking—consult your manual for vehicle-specific steps.
- If a no-start condition occurs (indicating theft system activation), conduct a theft relearn: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times; this syncs the system without tools in most GM cases.
