Restore Your Truck’s 4WD Capability with a Plug-and-Play Solution
Is the dreaded “Service 4WD” light staring back at you from the dash of your 2007-2013 Sierra 1500? Are you frustrated by a four-wheel drive system that won’t engage, or gets stuck in one mode? You’re not alone. As a technician with over two decades of experience, I’ve seen countless GM trucks come into the shop with these exact issues. More often than not, the culprit is a failed Transfer Case Control Module (TCCM). This small electronic brain is the command center for your 4×4 system, and when it fails, it can leave you stranded without the traction you depend on.
Don’t waste time and money at the dealership for a complex programming procedure. We offer a direct, reliable fix with this TCCM, part number 24239190. The critical difference? We program it specifically for your truck before it ships. Just provide us with your Vehicle Identification Number (VIN) during checkout, and we’ll flash the module with the latest, most stable software from GM. This ensures perfect communication between the TCCM and your truck’s other systems, eliminating the need for expensive scan tools or a trip to the dealer. This is the most efficient way to get your 2007-2013 Sierra 1500 TCCM replaced and your truck back to full function.
A Technician’s Notebook: The Intermittent 4WD Mystery
I remember a 2011 Sierra 1500 that came in with a frustrating problem. The owner said his 4WD would work fine for weeks, then suddenly refuse to engage, with the service light popping on. He’d already replaced the dash switch and the transfer case encoder motor, but the problem persisted. After hooking up my scanner, I saw intermittent communication loss codes (U-codes) pointing to the TCCM. On the bench, I found a hairline crack in a solder joint on the module’s circuit board—a classic failure point caused by years of vibration and thermal cycles. Replacing the faulty module with a correctly programmed unit solved the issue for good. It’s a reminder that sometimes the simplest-looking component is the root of the most complex-seeming problem.
Common Signs of a Failing TCCM
If your truck is experiencing any of the following, a faulty TCCM is the likely cause. Replacing your 2007-2013 Sierra 1500 TCCM can be the definitive solution.
- ✔ “Service 4-Wheel Drive” message on the instrument cluster.
- ✔ 4WD indicator lights on the selector switch do not illuminate or flash without reason.
- ✔ Inability to shift into or out of 4-High, 4-Low, or Auto 4WD.
- ✔ The vehicle feels like it’s stuck in 4WD, causing binding on dry pavement.
- ✔ Diagnostic Trouble Codes (DTCs) such as C0327, C0398, or various U-codes (e.g., U0102) related to lost communication with the TCCM.
DIY-Friendly Installation Guide
Replacing the TCCM is a straightforward job that most DIYers can handle in under 30 minutes with basic hand tools. Our pre-programmed module makes it a true plug-and-play repair.
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: The TCCM is typically located on the driver’s side, up under the dashboard to the left of the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs that need to be depressed. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed TCCM into place. Securely plug in the electrical connectors, ensuring they click to confirm a solid connection.
- Final Steps: Reinstall any dash panels you removed. Reconnect the negative battery terminal. Start the truck and test your 4WD system to confirm the repair is complete. The “Service 4WD” light should be gone!

Frequently Asked Questions
Do I need to do any programming myself?
No. This module arrives fully programmed to your vehicle’s VIN. It is ready for installation right out of the box, with no need for special tools or a trip to the dealership.
How do I provide my VIN?
Simply enter your 17-digit VIN in the designated field during the checkout process. We cannot program and ship the module without it.
Is this part difficult to install?
Not at all. It’s a plug-and-play component located under the driver’s side dashboard. Most people with basic hand tools can complete the swap in under 30 minutes.
What happens if I install it without programming?
An unprogrammed TCCM will not communicate correctly with your truck’s other systems, like the engine and transmission controllers. This will result in the 4WD system not working and will likely trigger warning lights and error codes.
Will this fix my ‘Service 4WD’ light?
In a vast majority of cases where the TCCM is the cause of the problem, yes. This module is the most common failure point for the symptoms listed above. However, you should always ensure other components like the transfer case motor and dash switch are functioning correctly.
Is this compatible with my 2007 Sierra?
This fits the 2007 ‘new style’ (NBS) Sierra with the smooth door skin. It does not fit the ‘classic’ body style from that year. Please verify your body style before ordering.
