Restore Control of Your 4WD System
Is the dreaded “Service 4 Wheel Drive” message lit up on your 2008-2013 Chevrolet Avalanche 1500’s dashboard? Are you unable to switch between 2WD, 4HI, or 4LO? You’re likely dealing with a faulty Transfer Case Control Module (TCCM), the electronic brain of your truck’s 4×4 system. When it fails, it leaves you without the traction and control you depend on. This pre-programmed TCCM is the direct, no-hassle solution to get your four-wheel drive working flawlessly again.
We take the guesswork and expensive dealership trips out of the equation. Simply provide us with your vehicle’s VIN during checkout, and we will program this module with the latest official GM software specific to your truck. It arrives at your door ready for a simple plug-and-play installation, restoring full functionality without the need for specialized scan tools or costly programming fees.
From the Diagnostic Bay
I’ve seen this exact issue hundreds of times in my 20+ years as a technician. A customer brings in a Silverado or Sierra, frustrated that their 4WD selector switch does nothing. The lights might blink and then go out, or the “Service 4WD” message stays on constantly. A quick scan often reveals codes like C0327 (Encoder Circuit Malfunction) or U0102 (Lost Communication With TCCM). While sometimes it’s the encoder motor, a very common culprit on these GM trucks is internal failure of the TCCM itself due to heat cycles and component aging. Replacing it with a pre-programmed unit like this is the most efficient and reliable fix.
Is Your Truck Exhibiting These TCCM Failure Signs?
A failing TCCM can cause a range of frustrating symptoms. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ “Service 4 Wheel Drive” or “Service 4×4” message displayed on the instrument cluster.
- ✔ Inability to shift the transfer case into or out of 4HI, 4LO, or 2WD.
- ✔ Indicator lights on the 4WD selector switch are blinking or completely dark.
- ✔ The vehicle feels stuck in one drive mode, regardless of switch position.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as C0306, C0321, C0327, C0569, or U0102.
A Straightforward Guide to Installation
You don’t need to be a professional mechanic to install this part. With basic hand tools, you can have your 4WD system back online in under an hour. This 2008-2013 Avalanche 1500 TCCM is designed for a direct fit.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the Module: On most compatible GM trucks and SUVs, the TCCM is located on the driver’s side, up under the dashboard to the left of the steering column. It’s a small black box with a few electrical connectors.
- Remove the Old TCCM: Carefully unplug the electrical connectors. Then, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed TCCM in the same location. Securely plug in all the electrical connectors—they will only fit one way.
- Final Step: Reconnect the negative battery terminal. Start your vehicle and test the 4WD selector switch to confirm that all modes are engaging correctly. The “Service 4WD” light should now be off.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is specific to your vehicle.
Is this part difficult to install myself?
Not at all. For most DIYers with basic tools, this is a straightforward job that takes less than an hour. The module is typically located under the driver’s side dashboard and is held in by a few bolts or clips. Since it comes pre-programmed, no special computer equipment is needed.
Will this fix the “Service 4WD” light permanently?
Yes, if the TCCM is the root cause of the problem. This module is the most common failure point for these symptoms. By replacing it with a unit flashed with the latest GM software, you are installing a durable and reliable solution.
What happens if I install it without programming?
An unprogrammed TCCM will not work in your vehicle. The module must be able to communicate with your truck’s other computers, which is only possible when it is correctly programmed to your specific VIN. We handle this for you before shipping.
Does this TCCM work for multiple part numbers?
Yes. This single module is a compatible replacement for a wide range of original GM part numbers, including 24261367, 12588096, 24241143, 24249095, and many others listed in the description. It is the correct service replacement for all of them.
