2002 Chevrolet Silverado BCM (BCM) DPNU – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2002 Chevrolet Silverado’s doors refusing to lock, interior lights flickering erratically, or the alarm system going haywire during a rainy drive home? These frustrations often stem from a failing Body Control Module (BCM), especially in older trucks exposed to harsh weather or electrical glitches. As a seasoned mechanic who’s diagnosed countless GM vehicles, I’ve seen how a compromised BCM disrupts everything from power windows to anti-theft systems, leading to DTC codes like P1626 or U1000 that leave you stranded. The good news? Our pre-programmed BCM, flashed with the latest GM updates using your VIN, directly addresses these issues. Compatible with part numbers including DPNU, 15063578, 15081796, 15095334, 19208537, and DKAK, it ensures seamless integration. This isn’t just a replacementโit’s a reliable solution that clears persistent trouble codes, restores smooth electrical operations, and enhances overall vehicle reliability for daily commutes or towing heavy loads.

Common Issues & How This Fixes Them
In my two decades fixing GM trucks, I’ve encountered plenty of 2002 Silverado owners frustrated by BCM failures. One common problem is intermittent power door locks that fail to respond, often caused by corroded connectors or software glitches from moisture ingressโthink after a heavy rain in humid climates. This not only compromises security but can trigger theft deterrent system errors, leaving your truck vulnerable. Another issue: dashboard warning lights staying on, linked to faulty BCM communication that throws codes like B1480, affecting battery drain and even starting problems. I’ve seen this escalate to no-start scenarios during cold mornings, stranding drivers. Erratic wiper or headlight operation is also frequent, stemming from degraded internal circuits, which poses safety risks on highways. Replacing with our VIN-programmed BCM resolves these by restoring precise control over body electronics, clearing codes efficiently, and preventing recurrence through updated firmware. For instance, a client with a towing setup noticed improved brake light consistency post-install, avoiding potential accidents. If you’re asking, “Why does my Silverado’s alarm keep false-triggering?” it’s likely BCM-related voltage irregularitiesโour module stabilizes this, drawing from proven diagnostics that go beyond basic scans to analyze wiring integrity for long-term fixes.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates before shippingโensuring it’s ready to plug in.
- Disconnect the battery to avoid electrical shorts; locate the BCM under the steering column or center dash, depending on your Silverado’s configuration.
- Remove the old module by unplugging connectors carefullyโinspect for corrosion and clean if needed to prevent future issues.
- Install the new BCM, reconnect all plugs securely, and reconnect the battery; start the engine to verify basic functions like lights and locks.
- Perform post-install procedures: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light, and check if brake pedal recalibration is required for optimal brakingโconsult your manual or a tech if unsure.
- If a no-start occurs (rare), initiate theft relearn: Insert key, turn to ON for 10 minutes, off for 5 seconds; repeat three times until the security light flashes, then start the engine.
