How To Reset Transfer Case Control Module- 05 Steps

The transfer case control module is one of the electronic innovations that manages to balance the operation of different areas of the vehicle.

This includes control over the transfer case, transmission, electronic differential lock, etc. That is why it is essential to know how to reset this module.

Step 1: Turn off the vehicle

Regardless of the type of vehicle with the transfer case control module, it is necessary to park and turn off the vehicle.

Performing this procedure can be very simple once the user carefully performs each of the following steps. Many novice users may make some kind of mistake in one of these steps.

Depending on the error made, other parts and functions of the vehicle could become unbalanced and malfunction. After turning off the vehicle, the key must be removed.

When this occurs, the operator must press your transmitter’s block switch and the door opens.

This same button should be pressed two times within a few seconds. Once the buttons have been pressed, the door should be closed.

Step 2: Turn the key

Once the previous step has been performed, the ignition button should be turned to one side and the other in just 5 seconds.

This switch should be placed in the ON state followed by a quick return at an OFF state.

This short procedure must be performed at least four times to obtain the expected result and continue with the procedure.

With the transmitter, the lock button should be pressed only once, and this must be done precisely while the key is turned back toward an OFF setting from the ignition switch position.

Step 3: Reset button

There is a reset button, which is usually installed near the instrument panel. This button is located near the driver’s seat for easy operation.

So once the person finds this button, he/she should press and hold it. Pressing this button for longer than just one second will suffice.

It is essential to repeat the ignition switch procedure here, turning it from one side to the other two times. This means that the switch must be rotated between the ON and OFF settings.

Step 4: Performing the reset

If the previous step has been performed, the user turns any starter key exactly at an OFF setting.

That is why it is necessary to have the transmitter press the lock button at this very moment, and this step must be performed only once at the indicated moment.

Here, it is possible to see a message indicating CHECK TRANS for a few seconds. This message appears once the TCCM has been reset.

Once this message disappears from the related screen, it is also possible to notice that your reset switch no longer blinks.

Step 5: Completing the procedure

Any starter key must be turned to complete the TCCM reset procedure, and this procedure should be performed only once by turning the key from ON to OFF.

In some situations, it is useful to notice a clear sign that the issue is still unresolved.

This is precisely what happens when a CHECK TRANS warning continues to appear on the corresponding display. However, it is still a straightforward procedure anyone can perform in most cases.

You must be aware, nonetheless, that some problems with the TCCM may still occur. So, if this is what happens, it is essential to have expert workmanship and vehicle diagnosis.

This may be the best way to fix some problems and avoid standard electronic component errors.

Transfer Case Control Module

Many vehicle systems have various modules that control different functions more efficiently.

One such module is the transfer case control module, which can be recognized by the acronym TCCM, and it is one of the fundamental parts of electronic shifting in 4WD systems.

This module is responsible for controlling the transfer case, the transmission operation, the electronic differential lock, and the traction on each of the wheels.

That is why there are many inconveniences when this module has an unbalanced or unconfigured operation. Hence, it may be beneficial to be aware of the reset procedure.

What Does The TCCM Do?

The TCCM performs a wide variety of tasks to complement the operation of some vehicles with automatic transmissions.

It is an automated part that operates electronically to perform the following tasks.

  • Gear shifting: the TCCM uses a data set that comes from the engine control unit. This data is received and processed to properly regulate the best way and time the vehicle shifts gears. So, this increases the accuracy of the vehicle’s gear shifting.
  • Controls and sensors: the control module of the transmission box works with a set of sensors to capture the necessary data. In turn, this same module also sends a set of data and signals to the lock-up clutch. This is a mechanism for regulating fuel power and efficiency.
  • Data storage: This module also performs storing information since it is a mechanical and electronic part. It is a set of data related to the vehicle’s transport network. Depending on the driving conditions, all this information is helpful to make the correct and precise changes.

Each of the TCCM functions indicates an error that can cause different problems. Some of them can be as simple as a delay in acceleration.

Anyway, it is advisable to verify the operation of this module from time to time.

Where Is The Transfer Case Control Module Located

Resetting the transfer case control module is a valuable procedure for balanced operation.

Beyond that, it is essential to know the location of this module, and this is because it is a critical part that controls various aspects of all-wheel-drive vehicles.

In most models that include this module, the location of this part is near the control panel. Precisely this is the steering column panel.

The transfer case control module is located from the driver’s position.

This location allows for much easier troubleshooting of errors in processing requests, verification, and execution of the system and its performance.

Accessing this module can be very important based on some of the most common symptoms detected.

Some of the most common problems are unusual noises, improper gear shifting, water accumulated in the transfer case, among other driveshaft, or differential problems.

Transfer Case Control Module Reprogramming

The transfer case control module has specific programming to control various vehicle functions.

However, there are situations in which this module could become unprogrammed and incorporate some errors in its operation. Therefore, there are some simple steps to reprogram this module.

Step 1: Scan tool

Before starting this procedure, the vehicle should not be plugged into a charger. At the same time, the battery must be completely charged and in a good state.

If it is a module replacement, the new unit must be installed before starting this procedure. Once the module installation is done, it is necessary to have the scan tool.

Step 2: Connect the tool

When the user has considered each of the aspects of the previous step, he must connect the scan tool he has to his vehicle.

These types of tools usually provide a wide variety of functions. Therefore, it is advisable to have the necessary knowledge and experience to use this tool.

Once the tool is connected, its operation must be turned on. Most tools provide the service programming function.

In this manner, the user must choose the car from the tool scanner. So, the scan tool must be compatible with the vehicle with the transfer case control module.

Step 3: Obtaining data

Once the vehicle has been selected in the scan tool, information must be requested by pressing the appropriate button on the tool.

After completing this task, the tool can be turned off. This is because it is necessary to connect these tools to the computer station.

Then, there is a series of steps from the reprogramming menu.

The computer station needs the information obtained from the vehicle in the scan tool, and this allows it to indicate to the computer station the type of module that needs to be reprogrammed.

The vehicle, module, and type of programming, among other things, must also be selected.

Step 4: Completing the reprogramming

Once the previous step has been completed, the tool must have the data file. Therefore, you must reconnect this tool to the vehicle at this point.

Keeping the engine off, the ignition must be switched on. In the tool, the service programming function must be selected. Finally, press the programming switch on the device.
