Restore Control Over Your Truck’s Electronics
Are you chasing down electrical gremlins in your 2001 GM truck or SUV? Flickering interior lights, power windows with a mind of their own, a security light that won’t turn off, or even a frustrating no-start condition can all point to one culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can make your daily drive a nightmare. This isn’t just an inconvenience; it’s a breakdown in your vehicle’s core communication system. We offer a reliable, straightforward solution: a replacement 2001 Yukon BCM, professionally programmed to your vehicle’s specific VIN before it ever leaves our facility.
From the Diagnostic Bay
“A customer’s 2001 Silverado 1500 came in last week with a classic case of BCM failure. The radio would turn on and off randomly, the power locks worked intermittently, and the battery would be dead every few mornings. He had already replaced the battery and checked the alternator. After hooking up the scan tool, I saw multiple communication loss codes with various modules. This is a tell-tale sign. Instead of sending him to a dealership for a new module and programming, we supplied one of these VIN-programmed units. The install took less than an hour, and every single electrical issue was resolved on the spot. He drove away with a reliable truck and saved hundreds compared to the dealer quote.”
Is Your GM Truck Showing These Symptoms?
A failing BCM can manifest in numerous ways. Over my 20+ years in the shop, I’ve seen these issues countless times. If your vehicle is experiencing any of the following, a faulty BCM is the likely cause:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The security system engaging randomly or preventing the engine from starting (Passlock issues).
- ✔ Intermittent warning lights on the instrument cluster.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
- ✔ The radio or climate control system behaving unpredictably.
The Smart Solution: VIN-Programmed and Ready to Install
The biggest hurdle in replacing a modern vehicle computer is programming. Traditionally, this meant having your truck towed to a dealership, paying for labor, and waiting for them to sync the new part. Our process eliminates that entire headache. When you order, you provide us with your vehicle’s VIN. We then flash this 2001 Yukon BCM with the latest, most stable software directly from GM. It arrives at your door ready for installation, turning a complex electronic repair into a manageable DIY job or a much faster task for your professional mechanic.
A Straightforward Guide to Installation
Replacing the BCM is typically a simple process located under the driver’s side dashboard. While specific steps can vary slightly between a Yukon and a Sierra, the general procedure is consistent.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most of these GM trucks and SUVs, the BCM is mounted to the left of the steering column, often behind a lower dash panel.
- Remove Connectors: Carefully unplug the multiple wiring harnesses connected to the old module. They have locking tabs that need to be depressed. Do not force them.
- Swap the Module: Unbolt or unclip the old BCM from its mounting bracket and install the new, pre-programmed unit in its place.
- Reconnect Everything: Plug all wiring harnesses securely into the new BCM. Reconnect the negative battery terminal.
Important Final Steps After Installation
Once your new BCM is installed, a couple of critical procedures are required to ensure all vehicle systems operate correctly and safely. This is not a step to be skipped.
- Airbag System Reset: The airbag warning light will likely be on. You must perform the ‘Setup SDM Primary Key in BCM’ procedure using a compatible bi-directional scan tool. This re-establishes communication between the new BCM and the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Sensor (BPPS) Relearn: Some vehicles require a recalibration of the brake pedal position sensor. This ensures the brake lights and stability control systems receive accurate input. This is also performed with a high-level diagnostic tool.
Note: If you are not comfortable performing these relearn procedures, a local qualified technician can complete them quickly for you.

Frequently Asked Questions
Do I really need to provide my VIN?
Yes, providing your Vehicle Identification Number (VIN) is absolutely essential. We use it to load the correct, vehicle-specific software and calibrations from GM. This ensures the 2001 Yukon BCM works perfectly with your truck’s options and security system right out of the box.
Is this a plug-and-play part?
For the most part, yes. The module is pre-programmed, so the main installation is plug-and-play. However, as noted, you will need to perform the ‘Setup SDM Primary Key’ and potentially the ‘Brake Pedal Relearn’ procedures with a scan tool to finalize the installation and clear any warning lights.
What happens if I don’t do the airbag and brake relearn procedures?
If you skip these steps, the airbag warning light will remain on, meaning the SRS system is disabled and will not deploy in an accident. The brake lights may also not function correctly. For safety, these procedures are mandatory.
Will this fix my ‘Security’ light issue?
In most cases, yes. A failing BCM is a very common cause of issues with the GM Passlock security system. A new, correctly programmed BCM typically resolves these security-related starting problems.
How do I find my original part number?
The part number is printed on a white label directly on your original BCM. However, since this unit replaces multiple part numbers (09375899, 9392990, 09370249, 19180223), the most important thing is to match your vehicle model and year from our compatibility list and provide your VIN.
