2011 – 2013 GM – Body Control Module (BCM) 15880684 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic dashboard lights flickering on your 2011-2013 GM vehicle during a rainy drive, or wondered “why is my Chevy Impala’s power windows failing intermittently?” These frustrating symptoms often trace back to a faulty Body Control Module (BCM), disrupting everything from lighting controls to security systems. As a seasoned auto repair advisor, I’ve seen countless owners struggle with BCM failures that trigger diagnostic trouble codes (DTCs) like U0140 or B1370, leading to no-start conditions or unreliable electronics. Our pre-programmed BCM, part number 15880684, arrives ready for your specific VIN, flashed with the latest GM updates to restore seamless operation. Compatible with a wide range of models including Equinox 07-09, Express vans 08-12, Tahoe 10, and more—such as Savana 2500 Van 11-12 or Caprice 11-13—this unit clears persistent DTC codes and enhances overall vehicle reliability. By addressing root causes like moisture intrusion or electrical shorts, it prevents recurring issues, saving you from costly towing and downtime.

Common Issues & How This Fixes Them
In my two decades fixing GM vehicles, BCM problems often manifest as dashboard warnings that won’t reset, or accessories like door locks malfunctioning randomly. For instance, in a 2011 Savana 2500 Van, exposure to harsh weather can corrode internal circuits, causing intermittent power failures and triggering codes such as B1325 for battery voltage issues. This leads to unsafe driving, especially at night when headlights flicker. Another common headache is in 2012 Traverse models where the BCM fails to communicate with the ECM, resulting in stalled engines or unresponsive climate controls—I’ve diagnosed this in shop scenarios where simple voltage spikes from alternator issues fry the module. Our pre-programmed BCM resolves these by providing updated firmware that strengthens signal integrity, preventing communication breakdowns and clearing stubborn DTCs. Owners of 2013 Caprice often report theft system glitches post-battery replacement; this unit recalibrates seamlessly, restoring security without extra programming. Beyond basics, it improves long-term durability against vibrations in heavy-duty vans, reducing the need for frequent diagnostics and ensuring consistent performance during long hauls.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates tailored to your vehicle.
- Disconnect the battery to ensure safety and prevent electrical surges during removal of the old unit.
- Locate the BCM—typically under the steering column in Tahoes or center dash in Express vans—and unplug connectors carefully.
- Install the new BCM, reconnect all wiring, and secure it in place following your model’s specific mounting points.
- Reconnect the battery and perform initial tests; if no-start occurs, initiate theft relearn by cycling the key from off to run (without starting) 3-4 times, waiting 10 minutes each cycle per GM standards.
- Complete post-install procedures: Use a diagnostic tool for ‘Setup SDM Primary Key in BCM’ to reset airbag lights, and recalibrate the brake pedal if needed for optimal safety—consult your manual or a tech for variations.
