Restore Your Yukon’s 4×4 Capability Without a Dealer Trip
As a technician with over two decades of experience under the hood, I’ve seen countless GMC and Chevy truck owners come into the shop frustrated by that dreaded ‘Service 4WD’ light. Your powerful Yukon XL 1500 is built for capability, but when the Transfer Case Control Module (TCCM) fails, you’re left without reliable four-wheel drive. The TCCM is the electronic brain of your 4×4 system, and when it goes bad, you can get stuck in one mode, or lose the ability to switch altogether. This isn’t just an inconvenience; it’s a safety issue in bad weather or off-road conditions.
This is the definitive, hassle-free solution. This TCCM, part number 24239190, is a direct-fit replacement for your original module. The best part? We program it to your vehicle’s specific VIN before we ship it. This means no expensive trip to the dealership for programming, no special scan tools required. It arrives at your door ready for a simple, plug-and-play installation, loaded with the latest GM software updates to ensure peak performance and reliability.
From the Diagnostic Bay
I remember a customer with a 2011 Yukon XL who was quoted nearly $800 at the dealership to fix his ‘Service 4WD’ light. The diagnosis was a failed TCCM, and the bulk of the cost was for the new module and the labor to program it. He was a capable DIYer and felt defeated. I explained that the physical swap is incredibly simple—it’s the programming that’s the hurdle. We got him this exact pre-programmed module. He installed it himself in under 30 minutes in his driveway and saved over $500. That’s what this part is all about: empowering you to fix your own vehicle affordably and correctly.
Is Your Yukon Showing These Symptoms?
A failing TCCM can manifest in several ways. If you’re experiencing any of these, this module is very likely the solution you need. In my shop, these are the classic signs I look for:
- âś” ‘Service 4WD’ or ‘Service Four Wheel Drive’ message on the instrument cluster.
- âś” Inability to switch between 2WD, 4HI, 4LO, or Auto modes.
- âś” The 4×4 selector switch lights don’t illuminate or flash without engaging.
- âś” Vehicle is stuck in 4WD or, conversely, will not engage 4WD.
- âś” Diagnostic Trouble Codes (DTCs) stored in the system, such as U0102 (Lost Communication with TCCM) or C0327 (Transfer Case Encoder Circuit).
A Straightforward Guide to Installation
One of the biggest benefits of this pre-programmed module is the simple installation. You don’t need to be a master mechanic to get this job done. The TCCM is typically located under the driver’s side of the dashboard.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the old TCCM. On most 2007-2014 Yukon XL 1500 models, it’s mounted to a bracket to the left of the steering column, up under the dash.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have release tabs you’ll need to press. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed TCCM into place and securely plug in the electrical connectors. You’ll hear a click when they’re seated correctly.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test the 4×4 selector switch to ensure all modes engage properly. The ‘Service 4WD’ light should be gone.
Why Choose a Pre-Programmed 2007-2014 Yukon XL TCCM?
Choosing our VIN-programmed module is the smartest way to repair your vehicle. A new module from the dealer is just a blank box; it requires their proprietary tools to make it work with your truck. Used modules from a salvage yard are a gamble—they might be programmed for a different vehicle with different options, leading to compatibility issues or the same failure you’re trying to fix. Our solution for the 2007-2014 Yukon XL TCCM provides a reliable part with the correct, updated software, saving you hundreds in potential diagnostic and programming fees.
