Is Your 2002 GM Truck or SUV Acting Possessed?
If you’re dealing with a frustrating array of electrical gremlins in your 2002 Yukon, Tahoe, Suburban, or Escalade, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central computer that manages your vehicle’s body electronics. When it starts to fail, it can cause bizarre and unpredictable issues that seem unrelated, from flickering lights to a dead battery overnight.
From the Diagnostic Bay
We had a 2002 Tahoe come in that was driving the owner crazy. The dome lights would stay on intermittently, draining the battery. The power locks would work one minute and not the next. After checking fuses and wiring, we pinpointed the BCM. Swapping in a VIN-programmed module like this one solved every single issue in under 30 minutes. The owner went from wanting to sell the truck to loving it again.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not working at all.
- ✔ False warnings on the driver information center, like “Service 4WD”.
- ✔ Radio or climate control malfunctions.
- ✔ Unexplained battery drain that leaves you stranded.

Simple Installation & Post-Install Notes
The BCM is located under the driver’s side dashboard, near the steering column, making for a straightforward replacement. While the module is plug-and-play for most functions, some vehicles may require additional steps after installation:
- Airbag System Sync: If your airbag warning light illuminates after installation, a simple “Setup SDM Primary Key in BCM” procedure must be performed with a capable scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and traction control functionality.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.
