2002 – 2005 GM BCM (BCM) DPNU – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic door locks or dashboard lights flickering unpredictably in your 2002 Chevy Silverado during a rainy drive? Or wondered, “Why won’t my 2003 GMC Yukon start, and how do I fix BCM issues without a hassle?” As a seasoned auto repair advisor who’s diagnosed countless electrical gremlins in GM trucks and SUVs, I’ve seen how a faulty Body Control Module can turn a reliable ride into a frustrating puzzle. This pre-programmed BCM, tailored to your VIN with the latest GM updates, resolves those headaches swiftly. It’s compatible with part numbers like DPNU, 15063578, 15081796, 15095334, 19208537, and DKAK, fitting models from Astro vans to Sierra pickups in the 2002-2005 range. Beyond just swapping parts, this unit clears DTC codes related to body electronics, restores smooth power window operation, and enhances overall vehicle reliability—think improved towing stability for your Sierra 3500 without unexpected shutdowns. Drawing from real shop scenarios, I’ve helped owners avoid costly dealer visits by opting for VIN-matched modules that integrate seamlessly, often preventing issues like intermittent no-crank conditions in cold weather.
Common Issues & How This Fixes Them
In my two decades fixing GM vehicles, BCM failures often manifest as mysterious electrical symptoms that baffle DIYers. For instance, if your 2004 Chevy Blazer has doors that lock and unlock on their own, or interior lights that stay on draining the battery, it’s likely corrosion or internal faults in the original module causing communication breakdowns with other systems. This can trigger DTC codes like U1000 or B1480, leading to safety concerns such as malfunctioning airbags. Another common headache in 2002 GMC Yukons is erratic wiper operation or failure of the keyless entry, especially after exposure to moisture—I’ve traced these to degraded BCM circuits that disrupt signal processing. Replacing with our pre-flashed BCM eliminates these by providing updated firmware that clears error codes and stabilizes connections, improving response times for features like automatic headlights. For towing enthusiasts with a 2005 Sierra 2500, a bad BCM might cause trailer brake lights to flicker, risking accidents; this fix ensures reliable integration, boosting confidence on long hauls. Proactively addressing these not only saves on diagnostics but also prevents cascading failures, like when a faulty module overloads the alternator in high-mileage Suburbans.
Key Features & Benefits
- Pre-flashed with GM’s newest software updates using your VIN for plug-and-play compatibility, eliminating guesswork in 2002-2005 models like the Tahoe or Avalanche.
- Supports clearing persistent DTC codes, restoring functions such as power mirrors and theft deterrent systems for enhanced daily drivability.
- One-year warranty backs your purchase, giving peace of mind against defects—I’ve seen these hold up in rugged conditions better than stock units.
- No core charge means you keep your old part without extra fees, ideal for budget-conscious owners troubleshooting BCM problems in S10 pickups.

- Expert-matched to specific IDs like 15081796, ensuring it fits seamlessly under the steering column or center dash without modifications.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM precisely to your vehicle’s specs— this step is key for GM standards compliance.
- Disconnect the battery to ensure safety, then locate the BCM (typically under the steering column in pickups like the Silverado or center dash in Astros).
- Remove the old module by unplugging connectors and unbolting it—use a diagnostic tool to note any existing codes for reference.
- Install the new BCM, reconnect everything, and reconnect the battery; perform a quick system check for immediate functionality.
- For relearn procedures: If a no-start occurs post-install, initiate theft deterrent relearn by cycling the key from off to run (without cranking) three times, waiting 10 minutes each cycle—most vehicles adapt automatically.
- Reset the airbag warning light via the ‘Setup SDM Primary Key in BCM’ using a qualified scan tool; some may need brake pedal recalibration for optimal safety—consult your manual or a tech if unsure.
