U0114 Fault Code

Long Description

Fault code U0114 is a communication-related code that is logged when there has been a loss of communication with the four-wheel drive clutch control module.

The four-wheel drive clutch control module is essentially the brain for the four-wheel drive system. It is responsible for taking various input signals and calculating how this affects the four-wheel drive system.

Issues with the four-wheel drive clutch control module will typically come with a number of negative effects in terms of the system’s performance.

Of course, only vehicles with a four-wheel drivetrain can be susceptible to this fault code.

Ford, Jeep, Toyota, and Subaru are among the most common manufacturers for this fault code.

Other Signs of This Problem

There can be a number of noticeable issues when it comes to any control module fault code

One of the most obvious symptoms will be the presence of the Check Engine light on the dashboard. In addition to this, the four-wheel drive indicator light can also be either on or flashing.

This issue can also cause gear-shifting issues. Owners have reported that it can prevent the vehicle from shifting out of neutral gear.

In addition to this, some vehicles will not shift out of a certain gear at all. This can mean the vehicle is stuck in forward, reverse, or neutral.

It is important to look out for additional fault codes that may help pinpoint the cause of the issue. Be sure to look for codes like U0100, U0314, and U0414 as these all relate to the four-wheel drive clutch control module.

What Could Be The Problem?

There are a number of common issues when it comes to any control module problems. While each of these systems is different, they can share the same issues but pinpointing the exact cause can be a fairly extensive and laborious process.

Any control module fault can be the result of a defective battery. The electronic control modules cannot function on insufficient power.

One of the most likely causes for any communication loss with a control module is an open circuit in either the positive or negative controller area network (CAN) bus circuit.

Similarly, there may be a short-to-ground or short-to-power condition throughout this same circuit.

It is also possible, although somewhat more rare, that the four-wheel drive clutch control module itself is faulty.

Other issues can include loose connections or damaged wires in the control module circuit.

Fixes

Finding the cause of this issue in a methodical manner is the best way to avoid unnecessary labor. This is true of almost all communication-related fault codes.

It is important to address any additional fault codes that could be related to this issue first. This can massively save on time and effort.

It is also important to check that the battery is functioning properly. If the battery is faulty, it needs to be replaced.

If there are no additional fault codes, it is a good idea to have the four-wheel drive clutch control module checked for any faults. If it can be determined that it is faulty, it needs to be replaced.

The control module circuit should also be checked for any of the electrical issues mentioned previously. These should be fixed accordingly. The same goes for the CAN bus circuit.

Seriousness

Fault code U0114 is a moderately serious fault code. It can result in a number of performance issues when it comes to the four-wheel drive system, but it does not always pose a huge issue in terms of driveability.

It is a good idea to have this issue fixed as soon as possible.
