Ever dealt with erratic dashboard lights in your 2002 GMC Sierra, wondering “why is my BCM causing power window failures or intermittent no-start issues?” As a seasoned mechanic who’s diagnosed countless GM trucks, I’ve seen how a failing body control module can turn a reliable Sierra into a headache—think doors not locking properly or headlights flickering without reason. This pre-programmed BCM, featuring part number 15063578 and compatibles like 15081796, 15095334, 19208537, DKAK, and DPNU, arrives ready for your vehicle after we flash it with the latest GM updates using your VIN. It fits various 2002-2005 GM models, including Silverado pickups, Yukon SUVs, and S10 series, often located under the steering column or center dash.

In my experience, owners regain confidence on long hauls, knowing systems like anti-theft and interior controls work flawlessly.

Common Issues & How This Fixes Them
In the world of GM trucks like the 2002 GMC Sierra, BCM troubles often sneak up subtly before escalating. One frequent symptom? Dashboard warning lights flashing randomly, often tied to corroded connectors from moisture intrusion—I’ve pulled modules from Sierras exposed to leaks, finding oxidation that disrupts signals to lights and gauges. This replacement BCM resolves that by providing a fresh, sealed unit with updated firmware, restoring accurate readings and preventing false alerts. Another issue hits the power accessories: windows or locks failing intermittently, usually from internal circuit degradation after years of vibration on rough roads. Swapping in this pre-flashed module recalibrates those functions, drawing on GM’s latest protocols to ensure smooth operation. No-start conditions can also plague owners, sometimes linked to anti-theft system mismatches—though rare post-install, a quick key cycle often sorts it. From my shop days, I’ve advised Sierra drivers facing erratic wipers during rainstorms; a bad BCM overloads the network, but this fix stabilizes it, avoiding breakdowns in bad weather. Lastly, airbag lights staying on? That’s a safety red flag, often requiring a diagnostic reset after replacement to sync the SDM key. By fixing these, you sidestep broader electrical chaos, extending your truck’s lifespan with minimal fuss.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your 2002 GMC Sierra.
- Disconnect the battery to ensure safety, then locate the BCM—typically under the steering column in Sierra pickups.
- Remove the old module by unplugging connectors and unbolting it; inspect for any visible damage like corrosion for future prevention.
- Install the new BCM securely, reconnecting all harnesses carefully to avoid shorts.
- Reconnect the battery and perform any necessary relearns: If a no-start occurs due to theft system, cycle the key from off to on (without cranking) for 10 minutes, repeat up to three times.
- For airbag light reset, use a qualified scan tool to run the ‘Setup SDM Primary Key in BCM’ procedure; some models may need brake pedal recalibration for optimal safety—check your manual or consult a technician if unsure.
