A transfer case control module (TCCM) controls four-wheel-drive automobiles. A transfer case control module comprises a transmission and case controller. You can find it under the steering column on the driver side of each four-wheel-drive vehicle.
The system’s main aim is to process shift requests and prevent shift failure. The transfer case shift requests by verifying movements and speed and executing. What happens if you have a bad transfer case or when the transfer case module fails?
When there is a bad transfer case, the first thing to do is maintain acceleration and wait a few minutes. Thereafter, let go of the gas pedal and allow the system to relearn the code. You can repeat this cycle three to four times.
However, a quicker way to reset the transfer case control module is to use a 5-amp transmission control module fuse to reset the transfer case. You can read through how to reset a bad transfer case control module.
Why is it Necessary to Reset Your Transfer Case Control Module?
As stated earlier, the transfer case control module controls vehicle speed and transfer movements. This module is a sensitive part of the engine. Therefore, you need to know exactly when to rest it.
The first indication that your transfer case needs to rest is when you notice your driveshaft is not responding. The failure happens when the transmission starts falling along with the axles. After that, your encoder motor begins to malfunction.
Often, you may get a notification on the dashboard or a warning signal indicating that the transfer case is malfunctioning. Therefore, you need to pull over and reset your transfer case control module when you see these indicators. The dashboard is the interface on the driver’s side beyond the steering column.
How to Reset the Transfer Case Control Module?
You can use three different ways to reset the transfer case control module. They include:
- Turning off the accelerator
- Using jumper cables
- Using the TCCM fuse
You can use these simple ways to perform the transfer case reset in your garage.
Method 1: Turning Off the Accelerator
The following steps will help you to reset your transfer case control module.
The first thing to do is to ensure your ignition key is on. Thereafter, you can proceed with the next step in resetting your transfer case.
The next step is to put pressure on the accelerator pedal for five to ten minutes. This step is important because the transmission functionality is checked at this time.
Proceed by turning off the ignition key. You can also take your leg off the gas pedal, and the gas pedal acts as a combustion accelerator. Hence, the acceleration needs to be executed perfectly to reset the transfer case control module.
After taking steps one to three, wait a few minutes, then repeat the cycle.
Repeat the process about three to five times, and your transmission should work perfectly again.
Method 2: Using Jumper Cables
The universal procedure for resetting all ECUs and control modules is to unplug the jumper cables.
The first thing to do is unplug your battery’s negative terminal.
After that, with the aid of a screwdriver, gently unscrew the cable, ensuring it isn’t placed near the engine.
Seal the cable head with insulation tape to ensure safety and prevent it from charging any metal. Then, cover it with a clean piece of cloth or rug.
Next, connect your jumper cables to the negative and positive ends of the battery cable and allow it to run for about five to ten minutes.
The process helps to drain all the charge from the ECUs and battery.
Detach the jumper cables from the terminals after step three and return the opposing end of the battery cable to its original position.
Turn the ignition on and let the car run for about 15 seconds.
This process helps the return module to relearn its new values.
Switch the ignition off, then back on. Repeat the cycle some more times. After that, start the engine. Let the engine run for five minutes without interruption.
However, you must not start any other gadgets in the car like the radio, which will consume extra power. After the five minutes wait, you will notice whether or not the engine is idling perfectly.
Next, you need to run your gears and see if your sensors are working or still faulty. If you still notice discrepancies, repeat the entire process two to three times and try again. Moreover, it is essential to wait for a half-hour after each reset before trying again.
Method 3: Using the TCCM Fuse Box
The TCCM fuse does not require any extra gadgets to execute, and all you need to do is use the fuse to reset the module.
The first thing you need to do is find the fuse. The fuse is usually situated at the bottom of a fuse box in your car’s module. Once you have found it, remove the fuse from the fuse box.
Next, wait for 30 minutes or more without touching anything. The waiting period ensures no connection between the control module and the gas pedal.
Check if the fuse is working correctly or not after the 30-minute wait. If it’s not functioning correctly, you need to replace the fuse with a new one.
Once the new fuse is installed, turn on the ignition key and start your engine.
Once the engine is on, you will see the vehicle lights blinking. This means the TCCM reset is in progress. After that, you can turn off the engine and repeat the process five more times.
After the repeat cycle, turn on the engine and check if it is idling correctly. Also, check if the transmission or driveshaft has gained traction and is running perfectly or not.

Where is the Transfer Case Control Module Situated?
The transfer case motor is situated in the control panel at the driver side dash on the steering column of all-wheel drive vehicles. Transfer case failure causes the switch transfer case control module to slow down.
The switch transfer case’s location is the same for every four-wheel-drive mode vehicle.
If you notice any faulty transmission with the transfer case control module, you must reset your module.
We hope you have learned how to reset your TCCM fuse with the different methods we’ve outlined on your four-wheel drive vehicle.
For every four-wheel drive, the procedures outlined above works. For the TCCM fuse, you need to wait for a half-hour after removing the fuse before completing the process.
