2011 – 2013 – Body Control Module (BCM) 15819552 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic dashboard lights flickering on your 2011-2013 GM vehicle during a rainy drive, or wondered why your power windows and locks suddenly fail after a battery swap? These frustrating symptoms often point to a faulty Body Control Module (BCM), disrupting everything from interior lighting to security systems. As a seasoned auto repair advisor who’s diagnosed countless BCM failures in shops, I’ve seen how water intrusion or electrical spikes can corrupt this central hub, leading to DTC codes like P062F or intermittent no-start issues. Our pre-programmed BCM, part number 15819552, arrives flashed with the latest GM updates using your VIN for a perfect match—eliminating guesswork and ensuring seamless integration. Compatible with a wide array of models including Chevy Impala, GMC Yukon, Cadillac CTS, and more (full list below), this unit clears persistent error codes and restores reliable performance, improving overall vehicle responsiveness for daily commutes or heavy towing in models like the Express 2500 Van.
Key Features & Benefits
- Arrives fully programmed to your exact VIN, incorporating the newest GM software for enhanced stability and compatibility across 2011-2013 vehicles.
- Supports multiple interchangeable part numbers, such as 20815898 and 25892622, making it a versatile fix for various GM makes without sourcing headaches.
- Boosts electrical system reliability, preventing common failures like dimming headlights or erratic wiper operation, especially in harsh weather conditions.
- Includes a one-year warranty for peace of mind, covering defects and ensuring long-term dependability during high-mileage use.
- Eliminates the need for dealership visits by offering plug-and-play readiness, saving time and costs on professional flashing services.
- Enhances safety features by properly managing airbag and brake systems, helping to clear DTC codes and improve towing reliability in vans like the Savana 3500.
Common Issues & How This Fixes Them
In my two decades fixing GM vehicles, BCM problems often start subtly but escalate quickly. For instance, owners of 2011-2013 Chevy Tahoe models frequently report security system malfunctions, where the anti-theft feature locks out the ignition, stranding you with a no-start condition—usually triggered by module corruption from voltage surges. This replacement BCM resolves that by resetting communication protocols, allowing smooth engine starts without additional tools in most cases. Another headache is intermittent power accessory failures, like non-responsive door locks or windows in a GMC Yukon, often linked to degraded internal circuits causing DTC codes such as B1370. Our pre-flashed unit directly addresses this, restoring full functionality and preventing further electrical drain that could weaken your battery over time. For van owners like those with the Express 3500, BCM glitches might disrupt trailer lighting or ABS integration, compromising towing safety—especially with the 6.0L engine. Installing this part clears those codes, enhances signal reliability, and avoids costly downtime. Real-world tip: If you’re seeing dashboard warnings post-storm, scan for codes first; this BCM often fixes 80% of body-related errors without deeper diagnostics.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates tailored to your vehicle.
- Disconnect the battery to ensure safety and prevent electrical shorts during the swap—locate the BCM (typically under the steering column or center dash, depending on model like Tahoe or Impala).
- Remove the old module by unplugging connectors and unscrewing mounts; compare with the new unit to confirm fit.
- Install the new BCM securely, reconnect all wiring, and reattach the battery.
- Perform any necessary relearns: For theft system, if no-start occurs, cycle the key from off to on (without cranking) 3-5 times for 10 minutes each to sync—most GM models self-learn without issues.
- Test all functions like lights, locks, and wipers; if airbag light persists, use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ procedure, and recalibrate brake pedals if needed for optimal safety.
