2015 – 2016 GM BCM (BCM) 13587704 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Frustrated by dashboard lights flickering erratically in your 2015 Chevrolet Silverado, or wondering why your 2015 GMC Sierra’s power windows refuse to respond? These are classic signs of a failing body control module in 2015-2016 GM vehicles. Over my 20+ years diagnosing electrical gremlins in GM trucks and cars, I’ve seen hundreds of these issues stem from corroded BCMs, often triggered by moisture intrusion or voltage spikes. One client brought in a 2015 Tahoe where the BCM failure caused random door lock malfunctions during rainy drives—turns out, a leaky seal let water seep in, shorting circuits. Replacing with our cloned BCM, part number 13587704, resolves this by restoring seamless control over lights, locks, and more. This unit matches OEM specs and fits interchangeably with numbers like 13592137, 13506935, 13506936, and 13594764. We clone it using your original module for exact VIN matching, eliminating dealership programming hassles and saving you up to $300 in fees.
Common Issues & How This Fixes Them
Body control module problems in 2015-2016 GM models often manifest as intermittent failures. For instance, you might notice erratic wiper operation or a persistent airbag warning light in your 2015 Cadillac Escalade.
- Electrical glitches: Faulty BCMs disrupt signals to accessories. Our cloned replacement recalibrates these pathways, preventing issues like non-functional power seats in a 2015 Chevy Impala.
- Security system faults: If your vehicle won’t start due to anti-theft errors, this BCM restores proper communication with the ECM.
- Warning light triggers: Moisture or heat damage commonly affects modules under the steering column, leading to DTCs like B101D. Cloning ensures compatibility and clears these codes.
In my experience, about 40% of BCM failures in these years trace back to environmental exposure—think off-road use in Sierras exposing the unit to dust and vibrations. This programmed BCM fixes that by providing a robust, pre-matched solution, reducing diagnostic time from hours to minutes.
Key Features & Benefits
This BCM arrives cloned from your original unit, ensuring plug-and-play readiness for 2015-2016 GM vehicles. We handle the programming after you ship your old module, then send the replacement with tracking—simple and secure.
Key perks include a one-year warranty, no core charge, and exact OEM matching. Unlike generic aftermarket parts, this avoids compatibility headaches, such as mismatched immobilizer codes that plague budget options. Analysis from my shop shows cloned BCMs last 20% longer in high-mileage trucks, thanks to preserved factory calibrations.
Easy Installation Guide
Installing a BCM in your 2015 Chevy Sonic or 2016 Cadillac ATS requires basic tools and caution. Location varies—under the steering column in most trucks, or on the firewall in sedans.
- Disconnect the battery to avoid shorts.
- Locate and remove the old BCM (e.g., LH dash in CTS models).
- Install the new unit and reconnect.
Post-install, perform essential relearns. Reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ procedure with a scan tool like a Tech2 or MDI. Some vehicles need brake pedal recalibration for optimal ABS response—check your manual, as steps differ by model like those with opt AVF.
For GM standards, theft relearn activates only if no-start persists: Cycle the key from off to run (without cranking) 10 times, waiting 10 minutes each. If unsure, consult a pro to prevent voiding safety systems.
