2002 Chevrolet Avalanche BCM (BCM) DPNU – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2002 Chevrolet Avalanche acting up, like the interior lights flickering unpredictably or the power windows refusing to budge during a rainy drive? These glitches often point to a failing Body Control Module (BCM), especially in older GM trucks exposed to harsh weather. If you’re searching for “how to fix erratic electrical issues in 2002 Avalanche BCM” or “replacing BCM to clear DTC codes in GM vehicles,” this pre-programmed BCM is your reliable solution. It’s flashed with the latest GM updates using your VIN for a perfect match, ensuring seamless integration. Compatible with part numbers like DPNU, 15063578, 15081796, 15095334, 19208537, and DKAK, it restores full functionality without the hassle of dealership visits. Drawing from over two decades in auto diagnostics, I’ve seen how a fresh BCM not only clears persistent trouble codes but also enhances overall system reliability, preventing minor annoyances from escalating into major breakdowns.

Common Issues & How This Fixes Them
In my years working on GM trucks like the 2002 Chevrolet Avalanche, BCM failures often manifest in frustrating ways. For instance, you might notice the headlights dimming erratically or the door locks malfunctioning, caused by corroded circuits or voltage spikes from age and exposure. This can trigger DTC codes like P1626 or U1000, disrupting communication between modules and even affecting fuel efficiency. Another common headache is the airbag warning light staying on, often due to a mismatched or outdated BCM that fails to sync with the Supplemental Restraint System (SRS). Replacing it with this pre-programmed unit resolves these by restoring proper signal processing, which I’ve seen fix issues in scenarios where moisture from snowy drives infiltrates the dash area.
Then there’s the no-start condition, sometimes linked to anti-theft system glitches in these models. If your Avalanche cranks but won’t fire up, it’s likely the BCM isn’t recognizing the keyโ a quick theft relearn can sort it, but only if symptoms persist after install. Beyond that, intermittent wiper failures or radio glitches point to BCM degradation, impacting daily drives and safety. This replacement not only clears those codes but improves towing reliability by ensuring stable power distribution to accessories. From shop anecdotes, owners often overlook early signs like flickering gauges, leading to costlier fixes; catching it early with a VIN-matched BCM saves time and money, providing a deeper fix that aligns with GM’s integrated electronics design.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates tailored to your 2002 Avalanche.
- Disconnect the battery to ensure safety and prevent electrical surges during the swap.
- Locate the BCM under the steering column (or center dash in some compatible models) and carefully remove the old unit by unplugging connectors.
- Install the new BCM, reconnect all wiring, and secure it in place.
- Reconnect the battery and perform any necessary relearns: If a no-start occurs, conduct a theft relearn by inserting the key, turning to ON for 10 minutes (three cycles if needed), then starting the engine.
- Reset the airbag warning light via the ‘Setup SDM Primary Key in BCM’ procedure using a diagnostic tool; also, recalibrate the brake pedal if your vehicle requires it for optimal braking safetyโconsult your manual or a tech if unsure.
