2002 Chevrolet AVALANCHE 1500 Body Control Module (BCM) 15063577 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Have you ever been cruising in your 2002 Chevrolet Avalanche 1500, only to have the dashboard lights dim erratically or the power windows refuse to budge, leaving you stranded on a rainy off-road trail? These frustrating symptoms often point to a failing Body Control Module (BCM), the central hub managing everything from lighting to door locks in your GM truck. As a seasoned mechanic who’s diagnosed countless electrical gremlins in these classic rigs, I know how a faulty BCM can turn a reliable hauler into a headache—especially when towing heavy loads or navigating rough terrain. The good news? Our pre-programmed BCM, featuring the primary part number 15063577 and compatible with service numbers like 15081857, 19208544, 15095335, DKAJ, and DPNW, arrives flashed with the latest GM updates tailored to your VIN. This direct replacement clears persistent DTC codes, restores seamless functionality, and boosts overall electrical reliability without the hassle of dealership visits.

Common Issues & How This Fixes Them
In my two decades fixing GM trucks, I’ve seen BCM failures manifest in ways that disrupt everyday use. For instance, intermittent power window operation often stems from corroded internal circuits in the module, exacerbated by moisture ingress in high-humidity areas—common for 2002 Avalanche 1500 drivers who off-road frequently. This not only inconveniences you but can lead to safety risks if windows won’t close during storms. Replacing with our pre-programmed BCM resolves this by restoring robust signal processing, ensuring smooth operation and clearing related DTC codes like those tied to body electrical faults. Another frequent complaint? Erratic interior lighting or dome lights that stay on, draining the battery overnight. Causes include voltage spikes from aging wiring, which our updated module mitigates through enhanced surge protection, based on GM’s latest firmware. I’ve advised owners who’ve fixed this themselves, noting how it prevents dead batteries on job sites. Then there’s the issue of malfunctioning door locks or keyless entry, often triggered by software glitches in original units—especially after years of exposure to vibrations from towing. Our BCM, flashed to your VIN, recalibrates these systems, improving security and convenience. Lastly, airbag warning lights may persist post-failure; this replacement allows for proper resetting via diagnostic tools, enhancing occupant safety. Through these fixes, you’ll regain confidence in your truck’s performance, avoiding costly tow bills and downtime.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your 2002 Avalanche 1500.
- Disconnect the battery to ensure safety, then locate the BCM under the steering column—it’s typically secured with a few bolts for easy access.
- Remove the old module by unplugging connectors carefully, avoiding damage to pins, and install the new one in reverse order.
- Reconnect the battery and perform any necessary relearns: If a no-start condition occurs due to anti-theft, cycle the key from off to on three times, waiting 10 seconds each, to reset the system per GM standards.
- Use a qualified diagnostic tool to execute the ‘Setup SDM Primary Key in BCM’ procedure, resetting the airbag warning light for full safety compliance.
- Check for brake pedal recalibration if your vehicle requires it—test braking response and consult your manual or a pro to optimize performance and clear any lingering codes.
