Common Issues & How This Fixes Them

In my years diagnosing GM vehicles, I’ve seen countless 2010 Avalanche 1500 owners battle BCM-related woes. One frequent problem is erratic door lock behavior—locks clicking randomly or failing to respond to the key fob. This often stems from internal module corrosion or software glitches, exacerbated by moisture exposure during rainy drives. Replacing with this VIN-programmed BCM resolves it by refreshing the control logic, restoring responsive access. Another issue: interior lights staying on or not illuminating, draining the battery overnight. Causes include faulty relay controls within the BCM, leading to dead batteries on cold mornings. Our updated module fixes this by optimizing power distribution, preventing unnecessary drain. Security system malfunctions, like false alarms or no-start due to theft deterrent errors (think DTC B3031), are common too—especially after battery replacements. This BCM clears those by syncing perfectly with your vehicle’s immobilizer. For towing enthusiasts, intermittent trailer light failures can pose safety risks; the module’s enhanced firmware ensures consistent signaling. Lastly, power window glitches, where windows roll down but not up, often tie to BCM communication losses. Installing this part not only addresses the root cause but also incorporates fixes for related DTCs like U0155, drawing from patterns I’ve observed in shop repairs. Always scan for codes first to confirm, and remember, these symptoms can mimic wiring issues, so inspect harnesses during troubleshooting.

Easy Installation Guide

1. Provide your VIN after purchase so we can program the BCM with the latest GM updates before shipping.
2. Disconnect the battery to ensure safety and reset any temporary codes; locate the BCM under the steering column in your Avalanche.
3. Remove the old module by unplugging connectors and unbolting it—note positions to avoid mix-ups.
4. Install the new BCM, securing it firmly and reconnecting all harnesses; double-check for secure fits to prevent future shorts.
5. Reconnect the battery and perform a theft deterrent relearn if a no-start occurs: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times until the security light stops flashing.
6. Test all functions like lights, locks, and accessories; use a scan tool to clear any residual DTCs for optimal performance.
