How to Reset Transfer Case Control Module: A Step-by-Step Guide

If you own a four-wheel driving vehicle, then you already know the importance of maintaining the transfer case control module in optimal working condition. However, if your transfer case control system isn’t functioning correctly, it may need to be reset or even updated. In this post, we’ll demonstrate the step-by-step process of resetting the transfer case control module and give you all the information you need to ensure that your vehicle is back to its best performance in no time.

What is a Transfer Case Control Module?

A transfer case control module (TCCM) is an electronic component that regulates the transfer and balance of power between different sections of your vehicle. Specifically, the TCCM is responsible for controlling how power is distributed between the front and rear axles when in 2-wheel or 4-wheel drive. The module receives data and sensory inputs from several internal components and the driver’s control interface to determine the appropriate axle configuration.

How to Determine If Your TCCM Needs to Be Reset

It’s essential first to understand the signs that your transfer case control module may need to be reset. Some of the most common indications that you need to reset your TCCM are:

Dashboard Warning Lights

Dashboard-mounted warning lights are the most immediate indication that there may be an issue with your TCCM. If you notice any lights flashing on your dashboard that signals that there is a problem with the four-wheel drivetrain, it’s possible that the TCCM is malfunctioning.

Insufficient Performance

If you’re trying to use your four-wheel drivetrain, but it’s not engaging, it’s highly likely that there is a problem with your TCCM.

Unusual Noises

Unusual noises emanating from the transfer case or four-wheel drivetrain may also indicate that your TCCM is malfunctioning.

How to Reset Your TCCM

Step 1: Turn Off the Vehicle

The first step is to park and turn off your vehicle. Next, remove the key and, with your transmitter, press the lock switch and ensure that the doors are closed.

Step 2: Turn the Key

With the vehicle turned off, you need to insert the key and quickly turn it from the “ON” position to the “OFF” position and repeat at least four times.

Step 3: Find the Reset Button

Locate the reset button, which is usually installed near the instrument panel on the driver’s side.

Step 4: Reset Your TCCM

Press and hold the reset button for at least one second, and then turn the ignition key from “ON” to “OFF” twice. As you perform these steps, pay attention to the dashboard display. You should see a message indicating “CHECK TRANS” briefly. Once this message disappears, your TCCM has been successfully reset.

Step 5: Turn the Starter Key

Now, turn the starter key to the “OFF” position, and then press the transmitter lock button once, and the process is complete.
