Restore Your Truck’s 4WD System with a Plug-and-Play Solution
If you’re staring at a persistent “Service 4WD” light on the dash of your 2007-2013 GMC Sierra 1500, you’re not alone. As a technician with over two decades of experience, I’ve seen this issue countless times. The inability to switch into 4-Hi when a storm hits or into 4-Lo for a tough job isn’t just an inconvenience—it’s a critical failure of your truck’s capability. The culprit is often a faulty Transfer Case Control Module (TCCM), the electronic brain of your four-wheel-drive system. This module, part number 24261367, is the definitive, reliable fix you need, and we make the repair process easier than ever.
The biggest headache with replacing a TCCM has always been the mandatory, and costly, trip to the dealership for programming. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our experts will program the module with the latest GM software specifically for your truck. When it arrives at your door, it’s ready for a straightforward, plug-and-play installation. This saves you time, diagnostic fees, and programming charges, putting you back in control of your vehicle’s drivetrain.
Case Study: A Tricky Diagnosis
A customer brought in his ’11 Sierra 1500, frustrated because his 4WD switch was completely dead—no lights, no response. He’d already replaced the switch on the dash, assuming that was the simple fix. A quick scan with my diagnostic tool showed a U0102 code: Lost Communication with Transfer Case Control Module. This told me the problem wasn’t the switch, but the module itself. After 15 minutes of diagnostics, we confirmed the TCCM had failed internally, a common issue caused by voltage spikes or moisture intrusion over time. We installed one of our pre-programmed modules, and in less than an hour, the truck’s 4WD system was fully operational. The customer was thrilled to avoid a multi-day wait and a hefty bill from the dealership.
Is Your Truck Showing These 4WD Warning Signs?
A failing TCCM can manifest in several ways. If you’re experiencing any of the following, this module is likely the solution you need for your 2007-2013 Sierra 1500 TCCM failure.
- ✔ “Service 4WD” or “Service Four Wheel Drive” message is illuminated on your instrument cluster.
- ✔ The 4WD selector switch lights don’t illuminate or flash without engaging.
- ✔ You’re unable to shift between 2WD, 4WD High, or 4WD Low.
- ✔ The vehicle feels stuck in one drive mode, regardless of switch position.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as U0102 (Lost Communication With TCCM), C0327 (Encoder Circuit Malfunction), or other C-series transfer case codes.
- ✔ Audible clicking or grinding from the transfer case area during attempted shifts.
A Straightforward Guide to Installation
Replacing the TCCM on your Sierra is a job most DIY enthusiasts can handle in their own garage. With our pre-programmed module, you won’t need any special scan tools.
- 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 of the dashboard, up and to the left of the steering column. You may need to remove the 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. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCCM into place. Firmly reconnect the electrical harnesses, ensuring they click and lock securely.
- Final Steps: Reinstall any dash panels you removed and reconnect the negative battery terminal. Start the truck and test the 4WD selector switch to confirm proper operation. The “Service 4WD” light should be gone.
