Restore Your 4WD System with a Plug-and-Play Solution
If you’re staring at that frustrating ‘Service 4WD’ light on your 2007-2014 GMC Yukon XL 1500, you’re not alone. The inability to switch between 2WD, 4HI, or 4LO can be a major headache, especially when you need that extra traction. The Transfer Case Control Module (TCCM) is the electronic brain of your four-wheel-drive system, and when it fails, it can leave you stuck. This isn’t just an inconvenience; it’s a capability issue. We offer the definitive, hassle-free solution: a replacement TCCM, part number 24249095, that arrives at your door fully programmed to your vehicle’s specific VIN.
From the Diagnostic Bay
I had a 2011 Yukon XL 1500 roll into my shop last winter, just before a big snowstorm. The owner was panicked—his 4WD selector switch was dead, and the ‘Service 4WD’ message was glaring at him. He was stuck in 2WD. My scan tool pulled a U0102 code: Lost Communication with Transfer Case Control Module. After verifying power and ground at the TCCM connector, it was clear the module itself had failed internally. In the past, this meant a new module plus a trip to the dealer for expensive programming. Instead, we ordered one of these pre-programmed units. It arrived two days later, we plugged it in, and the 4WD system came back to life instantly. No dealer visit, no extra labor charges for programming. The customer was back on the road with full 4×4 capability before the first snowflake fell.
Is Your Yukon’s 4WD System Acting Up?
A failing TCCM can manifest in several ways. As a technician, I’ve seen these symptoms hundreds of times on this GM truck platform. If you’re experiencing any of the following, a faulty TCCM is the most likely culprit:
- ✔ ‘Service 4WD’ or ‘Service Four Wheel Drive’ message on the Driver Information Center (DIC).
- ✔ The 4WD selector switch lights are off or flash intermittently.
- ✔ Inability to shift the transfer case into or out of 4HI, 4LO, or Auto 4WD.
- ✔ The vehicle is stuck in one drive mode (e.g., stuck in 4HI).
- ✔ Diagnostic Trouble Codes (DTCs) such as U0102, C0327, or other communication-related codes pointing to the TCCM.
A Straightforward Guide to Installation
One of the biggest benefits of our VIN-programmed module is the simple, DIY-friendly installation. You don’t need advanced diagnostic tools or a trip to the dealership. Here’s a general guide to get you started:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the TCCM: On most 2007-2014 Yukon XL models, the TCCM is located under the driver’s side of the dashboard, to the left of the steering column. It’s a small black box with several electrical connectors.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs, so be gentle. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed TCCM into place. Securely plug in all the electrical connectors until they click.
- Reconnect and Test: Reconnect your battery terminal. Start the vehicle and test the 4WD selector switch. The lights should illuminate, and you should be able to cycle through all drive modes. The ‘Service 4WD’ message will be gone.

No. The main benefit of our service is that the module arrives pre-programmed. This is a plug-and-play installation, saving you the time and expense of a dealership visit for programming.
What causes a TCCM to fail?
TCCM failure is common and can be caused by several factors, including electrical surges, moisture intrusion from a leaky windshield or cowl, or simple internal component failure over time due to heat and vibration.
Is this a new or used part?
This is a high-quality, tested component that has been inspected and prepared for service. It is programmed with fresh, vehicle-specific software to ensure reliable, long-term operation.
Will this fix my ‘Service 4WD’ light?
If the TCCM is the source of the problem (as it often is with the symptoms listed above), then yes, this part will resolve the issue and turn off the warning light. We always recommend proper diagnosis to confirm the TCCM is the faulty component.
