Restore Full Electronic Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2002 GMC Yukon XL 1500 or another compatible GM vehicle? Issues like erratic power windows, intermittent door locks, a security light that won’t turn off, or even a no-start condition are often traced back to a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and unpredictable problems. This replacement BCM, part number 19208537, is the definitive solution to restore your vehicle’s factory functions and reliability.
From the Diagnostic Bay
We had a 2002 Sierra 2500 in the shop that was driving the owner crazy. The interior lights would flicker randomly, sometimes staying on and draining the battery overnight. He’d already replaced the battery twice. After checking for shorts and parasitic draws, we hooked up the scan tool and found communication errors with the BCM. We installed a VIN-programmed module just like this one, and the problems vanished instantly. It’s a common failure point on these trucks, but thankfully, it’s a straightforward fix with the right part.
Common Symptoms of a Failing BCM
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not working.
- ✔ The security or anti-theft light is illuminated on the dash, preventing the engine from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not responding.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Communication errors with other vehicle modules when checked with a diagnostic scanner.

Important Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require minor post-installation procedures for full system integration. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and requires a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, door locks, interior and exterior lighting, security system, wipers, and instrument panel warnings.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your order until we receive this information, as programming is essential for the part to function in your vehicle.
Is this BCM difficult to install?
For most compatible vehicles, the BCM is located under the steering column or in the center dash area. Installation typically involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. It is a manageable job for a DIYer with basic tools.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this fix my vehicle’s security light and no-start issue?
A faulty BCM is a very common cause of security system problems in these GM vehicles. By programming this replacement 2002 Yukon XL BCM to your VIN, it correctly syncs with your vehicle’s anti-theft system, resolving these issues in most cases.
What if my airbag light comes on after installation?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
