Are you battling frustrating electrical gremlins in your 2001 GM truck or SUV? A faulty Body Control Module (BCM) is often the culprit behind a wide range of perplexing issues, from flickering lights to non-responsive power accessories. This replacement BCM, part number 9375899, is the definitive solution to restore full functionality and reliability to your vehicle’s electronics. We take the guesswork and hassle out of the repair by programming the module to your vehicle’s specific VIN with the latest GM software updates before it ships. This means no expensive trips to the dealership for programming—it arrives ready for installation.
From the Diagnostic Bay
We had a 2001 Silverado in the shop with a classic ‘mystery’ battery drain. The owner had already replaced the battery twice and the alternator once. Every morning, the battery was weak. After hooking up a multimeter, we saw a significant parasitic draw. By pulling fuses one by one, we isolated the circuit to the BCM. The original module wasn’t properly entering its ‘sleep mode,’ keeping other systems awake all night and slowly draining the battery. Installing a VIN-programmed BCM like this one resolved the draw completely. It’s a common failure that often gets misdiagnosed as a bad battery.
Common Symptoms of a Failing 2001 Sierra Body Control Module
- ✔ Intermittent or total failure of power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior dome lights or exterior lamps (staying on or not turning on).
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ Inconsistent operation of the radio, instrument cluster gauges, or climate controls.
- ✔ False warning messages on the driver information center, such as ‘Service Vehicle Soon’.
- ✔ Unexplained battery drain that leaves you with a dead battery overnight.

Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require a simple relearn procedure after the new BCM is connected. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the new BCM with the airbag system and requires a professional-grade scan tool. This is only needed if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure correct brake light operation and to satisfy the traction control system.
- No Core Charge: You are not required to return your old module. You can keep it or dispose of it at your convenience.
Disclaimer: Specific procedures can vary by vehicle model and trim. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does the Body Control Module do on my 2001 Sierra?
The BCM acts as the central computer for your truck’s body electronics. It controls functions like power windows, locks, interior/exterior lighting, the security system, and instrument panel warnings.
Do I need to have this module programmed?
No. We handle all the programming for you before we ship the part. Just provide your VIN during or after checkout, and the module will arrive ready to install.
Where is the BCM located?
On most 2001 GM trucks and SUVs like the Sierra and Silverado, the BCM is located on the driver’s side of the dashboard, typically to the left of the steering column.
What if my airbag light turns on after I install it?
This is uncommon, but if it happens, the vehicle needs an ‘Airbag System Sync’ or ‘Setup SDM Primary Key in BCM’ procedure. This requires a professional scan tool to sync the new BCM with the airbag module and will turn off the light.
How do I send you my VIN?
You can add your VIN in the notes section at checkout or reply to your order confirmation email with it. We cannot ship your order until we receive the VIN.
