2013 – 2021 GM BCM (BCM) 22820314 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Frustrated by erratic lights and power windows failing in your 2013-2018 Chevy Impala or GMC Savana? You’re not alone—I’ve seen this countless times in my shop over two decades. What happens when your body control module starts glitching, causing doors to lock randomly or dashboard warnings to light up? Drivers often search “how to diagnose BCM failure in GM vans like Savana 2500,” only to face costly dealer visits. This pre-programmed BCM, part number 22820314 (also fits 22915542), solves that directly. We flash it with the latest GM updates using your VIN for a perfect match. Transitioning to benefits, this unit restores seamless control over body electronics, potentially saving you hundreds on repairs. In my experience, about 40% of BCM failures stem from moisture ingress in high-humidity areas—replacing with our updated module prevents repeats.
Common Issues & How This Fixes Them
Body control modules in 2013-2021 GM vehicles like Traverse or Enclave often fail due to electrical shorts or software corruption. Symptoms include intermittent power accessories, non-working remote keyless entry, or persistent airbag lights.
Over 20 years, I’ve diagnosed hundreds of these in vans like the Express 3500, where heavy use exposes them to vibrations and heat. One case: a fleet owner reported “BCM problems causing no-start in 2014 Savana van”—traced to faulty communication with the theft deterrent system.
This replacement BCM fixes these by integrating fresh GM firmware. It resolves codes like B101D or U0140, restoring functions without ongoing glitches.
Real Customer Story: A Captiva Sport owner in rainy Seattle dealt with flickering headlights for months. After swapping in our VIN-programmed BCM, everything stabilized—no more issues, even in wet conditions.

Easy Installation Guide
Installing a BCM in your GM vehicle requires basic tools, but precision matters. Disconnect the battery first to avoid shorts.
Locate the module—under the left dash in sedans like Impala, or center dash in vans like Express 1500. Swap it out, then reconnect.
Post-install, perform key relearn if no-start occurs: Insert key, turn to ON for 10 minutes, off for 30 seconds—repeat three times. Per GM standards, theft relearn activates only on no-start issues.
Reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ with a scan tool like Tech2. Some models need brake pedal recalibration for safety—check your manual or consult a pro if unsure, as steps vary by vehicle.
Pro Tip: Use dielectric grease on connectors during install to ward off corrosion, a trick that’s saved many clients from premature failures in humid climates.
