Is Your GM Vehicle Plagued by Electrical Gremlins?
If you’re experiencing a frustrating array of electrical issues in your 2015 Chevrolet Suburban, GMC Yukon, Cadillac Escalade, or other compatible GM vehicle, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, managing everything from your power windows and door locks to the interior lighting, security system, and even communication between other critical modules. When it starts to fail, it can create bizarre and unpredictable problems that can be difficult to diagnose.

Before condemning your BCM, always perform a full vehicle health check. Ensure your battery is fully charged and passes a load test, and check all main power and ground connections at the battery, engine block, and chassis. A weak battery or a poor ground can mimic many BCM failure symptoms by causing voltage drops and communication errors across the vehicle’s network.
Symptoms of a Failing 2015 Suburban BCM
A faulty Body Control Module can manifest in numerous ways, often intermittently at first. If you’re noticing any of the following issues, it’s a strong indicator that your BCM needs attention. This module is the key to restoring proper function and getting your truck or SUV back to its reliable self.
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or failing to turn on.
- ✔ The security system engaging randomly, causing a no-start condition (security light flashing).
- ✔ The horn honking unexpectedly or the panic alarm going off.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing for no reason.
- ✔ HVAC (heating and air conditioning) controls not responding correctly.
- ✔ Radio or infotainment system malfunctions.
- ✔ Communication error codes (U-codes) stored when scanned with a diagnostic tool.

Important Post-Installation Information
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a simple sync or relearn procedure after the new BCM is installed. This is standard for many modern vehicles and can sometimes be necessary to ensure all systems communicate perfectly.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag module and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control system performance.
Please consult a factory service manual or a qualified technician if you are unsure about performing these procedures.
