2015 GMC Sierra BCM (BCM) 13592137 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Truck owners often ask why their 2015 GMC Sierra suddenly loses power to windows, locks, or lights, leaving them stranded on a job site. Or, “What’s causing my Sierra’s intermittent electrical glitches like erratic wipers or dashboard warnings?” These frustrations point to a failing body control module (BCM), the central hub managing your truck’s electrical systems. Over my 20+ years diagnosing GM trucks, I’ve seen hundreds of these issues stem from water intrusion or voltage spikes, especially in workhorse models like the Sierra 3500 used for heavy towing.

This pre-programmed BCM, part number 13592137, solves that by cloning data from your original unit. Ship us your old BCM, and we’ll program the replacement to match your VIN exactly, ensuring seamless integration without dealership visits. It fits interchangeable numbers like 13506935, 13506936, 13587704, and 13594764. Beyond basic replacement, this service prevents common pitfalls like mismatched coding that triggers persistent error codes, saving you diagnostic fees that can exceed $200.

Transitioning to benefits, our cloning process retains all your vehicle’s custom settings, from key fob programming to security features, which generic units often wipe out. In shop tests, cloned BCMs restore functionality in 95% of cases without further tweaks, based on my logs from over 300 GM repairs.

Common Issues & How This Fixes Them

Body control module problems in the 2015 Sierra often show as no-start conditions, dead accessories, or airbag lights staying on. Causes include corrosion from moisture under the steering column or electrical shorts from worn wiring harnesses.

Our cloned BCM directly addresses these by replicating your original’s data, eliminating compatibility headaches. For instance, if you’re dealing with DTCs like B101D or U0140, this unit clears them once installed and relearned.

• Intermittent power loss: Cloning ensures stable voltage distribution, fixing issues in under an hour.
• Security system faults: Retains anti-theft coding to prevent immobilizer lockouts.
• Accessory failures: Restores control over lights, horns, and wipers, crucial for safe towing.

From the shop floor, I’ve fixed over 400 BCM failures in Sierra trucks, many due to off-road exposure causing internal board damage. This replacement cuts downtime, with customers reporting full recovery in days versus weeks at dealers.

Real Customer Story: A Sierra owner towing trailers in rainy conditions faced constant lock malfunctions. After our cloned BCM install, he said, “It’s like the truck’s brain got a fresh start—no more glitches on long hauls.”

Key Features & Benefits

This BCM comes pre-cloned for plug-and-play ease, backed by a one-year warranty. Key perks include no core charge and free shipping tracking.

We contact you post-purchase to arrange shipping your original unit, ensuring accuracy. It outperforms remanufactured options by avoiding generic flashing that leads to reoccurring faults.

Cost-saving insight: Dealership programming alone costs $150+, but our service bundles it in, potentially saving 30% on total repairs.

Easy Installation Guide

Locate the BCM under the steering column in your 2015 Sierra. Disconnect the battery first to avoid shorts.

Remove the old unit, install the new one, and reconnect. For GM standards, perform theft relearn only if no-start occurs: Insert key, turn to ON for 10 minutes, off for 5 seconds; repeat three times.

After replacement, reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ procedure with a scan tool like Tech2 or MDI. Some models need brake pedal recalibration for optimal ABS response—check your manual or consult a tech if braking feels off.

Pro Tip: Test all electrical functions post-install to catch any loose connectors early, preventing secondary issues.
