2002 – 2004 GM – Body Control Module DKAK Programmed To Your VIN

2002 – 2004 GM Various Models BCM (BCM) DKAK – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with erratic dashboard lights flickering on your 2002 Chevy Silverado, or wondered why your power windows suddenly quit working in a 2003 GMC Sierra? As a seasoned mechanic who’s diagnosed countless electrical gremlins in GM trucks and SUVs, I’ve seen how a failing Body Control Module (BCM) can turn a reliable ride into a headache. Questions like “how to replace BCM in 2002-2004 GMC Yukon for door lock issues” or “fixing intermittent no-start on 2003 Chevy Blazer BCM” pop up often in my shop. This pre-programmed BCM, compatible with part numbers like DKAK, 15063578, 15081796, 15095334, 19208537, and DPNU, arrives ready to install after we flash it with your VIN for the latest GM updates. It restores seamless control over body functions, from lighting to security systems, drawing on my experience where a proper match eliminates guesswork and prevents repeat failures.

Key Features & Benefits

• Arrives fully programmed using your VIN, ensuring plug-and-play compatibility with GM’s newest software for flawless integration and reduced diagnostic time.
• Backed by a one-year warranty, giving you peace of mind—I’ve installed these in vehicles like the 2002 Tahoe, and they hold up under daily driving demands.
• No core charge means you keep your old part without extra fees, simplifying the process for DIYers or pros alike.
• Supports a wide range of 2002-2005 GM models, including Silverado and Sierra pickups, helping resolve common electrical quirks without dealership markups.
• Incorporates expert-level flashing to match your vehicle’s exact specs, preventing issues like mismatched immobilizer codes that I’ve troubleshot in Astro vans.

Common Issues & How This Fixes Them

In my two decades fixing GM vehicles, BCM failures often stem from water intrusion, voltage spikes, or age-related wear in 2002-2004 models. Take a scenario where your 2002 GMC Yukon refuses to start intermittently, or the interior lights stay on, draining the battery—classic signs of a corrupted BCM. This can trigger diagnostic trouble codes (DTCs) like U1000 for communication loss or B1370 for device ignition faults, leading to safety risks like non-functional airbags. Another frequent complaint: “Why won’t my power locks work on a 2003 Chevy Blazer?” Often, it’s the BCM failing to relay signals, caused by corroded connectors under the dash. Replacing with this VIN-matched unit resolves these by restoring precise control over modules, and in real cases I’ve handled, it clears persistent codes without further tweaks. For trucks like the Sierra 3500, where heavy towing stresses electronics, this fix prevents cascading failures in systems like anti-theft or brake controls. Always scan for codes first; if moisture is the culprit, seal harnesses during install to avoid recurrence— a tip that’s saved clients from repeat visits.

Easy Installation Guide

1. Provide your VIN after purchase so we can program the BCM with GM’s latest updates tailored to your vehicle.
2. Disconnect the battery to ensure safety and reset systems—locate the BCM, often under the steering column in pickups like Silverado or center dash in vans like Astro.
3. Remove the old unit by unplugging connectors carefully, noting any ID labels for reference, and install the new BCM securely.
4. Reconnect the battery and perform initial checks for basic functions like lights and locks.
5. Address post-install procedures: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light, and recalibrate the brake pedal if your model requires it for optimal safety.
6. If a no-start occurs due to theft system mismatch, perform a simple relearn—insert key, turn to ON for 10 minutes, off for 30 seconds, repeat three times; consult your manual for variations.
