How to Fix AWD System Malfunction

One of the most important features on an all-wheel drive car is the ability to have power transferred to all four wheels. When this system malfunctions, it can be a huge inconvenience. In this article, I am going to discuss what to do if you experience an AWD system malfunction while driving. And, how to fix AWD system malfunction.

So, without further ado, let’s get started!

What does AWD system malfunction mean?

An AWD system is a four-wheel drive system that helps distribute power evenly to all four wheels of a vehicle. This helps with traction and stability, making it an essential feature – especially in inclement weather conditions.

There are two types of AWD systems: active and passive. Active systems have sensors that monitor traction and wheel slip. When it detects that one or more wheels are losing traction, it will send power to those wheels to help them regain grip. Passive systems, on the other hand, do not have sensors. Instead, they rely on the driver to manually select the appropriate mode for the conditions.

Most modern cars are equipped with active systems, as they are more effective and provide a better driving experience.

This can be caused by a blown fuse, disconnected battery, or loose wiring. Another common cause is a problem with the front or rear differential. This can be caused by a leak, damaged gears, or a worn-out bearing. Lastly, an AWD system may malfunction if there is an issue with the transfer case. This could be due to a broken chain or a faulty sensor.
