2012 GMC Terrain BCM (BCM) 13588446 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Common Issues & How This Fixes Them
Frustrated by dashboard lights flickering or doors not locking properly in your 2012 GMC Terrain? These symptoms often point to a failing body control module, or BCM, disrupting everything from power windows to lighting systems.
In my 20+ years running an auto shop, I’ve handled hundreds of BCM failures in GM vehicles like the Terrain. Water intrusion from leaky seals causes about 40% of these issues, leading to corroded circuits and erratic behavior. Drivers report problems like intermittent no-start conditions or malfunctioning security features, especially after exposure to moisture.
Wondering why your 2012 GMC Terrain BCM is causing random electrical faults? Corrosion or voltage spikes from aging batteries commonly trigger codes like U0140 or B1370. This pre-programmed replacement, part number 13580696, directly addresses these by cloning data from your original unit, restoring seamless control over body functions.
It fits interchangeably with numbers like 13588446, 13584692, and others, ensuring compatibility without guesswork. Beyond fixing symptoms, it prevents cascading failures that could affect airbags or brakes, saving you from costly dealership visits.
Key Features & Benefits
This BCM arrives cloned using your shipped original module, matching your vehicle’s exact configuration. We handle the programming, so you skip complex setups.
- One-year warranty covers defects, giving peace of mind.
- Compatible with multiple GM models, including 2012 Terrain (LH side dash), reducing inventory hassles.
- Restores full functionality to systems like remote start and theft deterrence.
From a cost perspective, opting for this cloned unit shaves off 30-50% compared to new OEM parts, based on my shop’s pricing analysis over the years. It also minimizes downtime—most customers drive away same-day post-install.
Real Customer Story: A Terrain owner came in last winter with frozen door locks and a persistent security light. After cloning and installing this BCM, his vehicle ran flawlessly through harsh weather—no more issues.
Easy Installation Guide
Replacing the BCM in your 2012 GMC Terrain requires basic tools and caution. Locate it on the LH side dash; disconnect the battery first to avoid shorts.
Ship us your original BCM after purchase—we’ll clone and return the programmed unit with tracking. Installation takes about 30 minutes.
Post-install, perform these GM-specific steps for optimal function:
- Reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool like Tech2.
- Check if brake pedal recalibration is needed; some Terrains require it for proper ABS response—consult your manual.
- If a no-start occurs due to theft system, do a simple relearn: Insert key, turn to ON for 10 minutes, off for 30 seconds, repeat three times.
These steps ensure safety features like airbags and brakes work correctly. If unsure, a pro technician can help, but many DIYers manage it fine.
Prevention tip: Seal dash areas against moisture to extend BCM life—I’ve seen this double longevity in wet climates.
