Our pre-programmed BCM, featuring part number 15095334, is flashed with the latest GM updates using your VIN for a perfect match.

Common Issues & How This Fixes Them
In my two decades fixing trucks like the 2002 GMC Sierra, I’ve seen BCM failures manifest in sneaky ways. One common problem is intermittent power window operationโperhaps your driver’s side window sticks halfway down during a summer storm, caused by corroded circuits in the aging module disrupting signals. This not only inconveniences you but can lead to water damage inside the cab. Replacing with our pre-programmed BCM resolves this by refreshing the control logic, ensuring consistent voltage delivery and preventing those frustrating stalls.
Another frequent headache involves dashboard warning lights staying illuminated, often tied to DTCs like U1000 or B1370, stemming from communication breakdowns between the BCM and other modules. Owners towing trailers might notice this more, as electrical loads amplify the issue, risking safety on highways. Our unit, updated via your VIN, clears these codes effectively and stabilizes the network, drawing from real shop scenarios where a simple swap fixed towing-related blackouts.
Door locks failing to engage remotely is yet another symptom, possibly from software glitches or internal faults, leaving your Sierra vulnerable in parking lots. This BCM addresses it head-on by incorporating GM’s latest firmware, which I’ve used to help clients regain full key fob functionality without pricey reprogramming. For those in colder climates, where moisture freezes components, this fix enhances reliability, reducing the chance of no-start conditions linked to security systems. Overall, it empowers you to troubleshoot confidently, saving time and avoiding repeated mechanic visits.
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.

- Remove the old unit by unplugging connectors and unbolting itโtake photos for reference to avoid mix-ups with wiring harnesses.
- Install the new BCM securely, reconnect all plugs, and reconnect the battery to power up the system.
- Perform necessary relearns: If a no-start occurs post-install, initiate theft deterrent relearn by turning the key to ON for 10 minutes (three cycles if needed), allowing the system to sync.
- Reset the airbag warning light via the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool, and check for brake pedal recalibration to maintain braking safetyโconsult your manual or a pro if unsure.
