Is a “Service 4WD” Light on Your Dash Ruining Your Drive?
Nothing is more frustrating than seeing a warning light that disables a key feature of your truck or SUV. When your GM vehicle’s four-wheel drive system stops responding, leaving you stuck in two-wheel drive, the Transfer Case Control Module (TCCM) is the most common culprit. This isn’t just an inconvenience; it’s a loss of the all-weather capability and rugged dependability you rely on. Get back the confidence to tackle any road, in any condition, with this direct-fit, pre-programmed TCCM.

An Expert’s Note on TCCM Failure
As a technician, I’ve seen dozens of these GMT900-platform trucks come in with 4WD issues. The TCCM is typically located behind the driver’s side of the dash, but it’s still susceptible to electronic failure over time from heat cycles and vibration. In the past, the repair meant installing a blank module and then paying for an expensive programming session at a dealership. This Programmed 2008-2014 Suburban 1500 Transfer Case Control Module changes the game. By handling the complex programming beforehand, we turn a multi-step, professional-level job into a straightforward component swap. It’s the smartest, most efficient way to get your rig back to 100%.
Frequently Asked Questions
Do I need to get this module programmed by a dealer?
Absolutely not. We program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation a simple plug-and-play process, with no additional programming or calibration required.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship your part until we receive your VIN.
Where is the TCCM located on my truck?
On most compatible models like the Silverado, Sierra, and Suburban, the Transfer Case Control Module is located on the driver’s side of the vehicle, mounted to a bracket up high behind the dashboard, near the parking brake pedal assembly.
Will this fix my “Service 4WD” light?
A failed TCCM is the most frequent cause of the “Service 4WD” light on these GM trucks and SUVs. While other issues can trigger the light, if you have codes pointing to the module or your 4WD is completely inoperative, this part is very likely the solution you need.
Is this compatible with my 2007 model?
This module fits the ‘new style’ 2007 models, often referred to as GMT900 platform, which have a smooth door skin. It does not fit the ‘classic’ 2007 models (GMT800 platform). We verify every order with your VIN to guarantee correct fitment.
