What is 4WD?

4WD stands for “Four Wheel Drive”. All the cars are one of the four types of drivetrains: the front wheel, rear wheel, four wheels, and all-wheel drive. This classification means how your wheels work to provide power to the car.

Four-wheel drive is one of the most common and popular types of drivetrains. This type of drivetrain means that the engine offers the maximum capacity to each wheel when the car is driving.

Driving a four-wheel drive needs more fuel and power. While driving in rough terrain, it is preferred by drivers as it allows better control over the vehicle than other drivetrains.

What does ‘Service 4WD’ mean?

Vehicles having a four-wheel drive system have a light to indicate when there is an issue with the system. It is called “Service 4WD”. A code is generated in the computer’s memory that underlines a problem with this light turning on.

Problem with car

When your vehicle says “Service 4WD “, it means an issue with the 4WD system. Some people think that this message indicates that the car needs regular maintenance and tend to ignore it. But since there can be a significant problem, it must be diagnosed and treated by 4wd servicing mechanics.

Incomplete shift gear

Sometimes the light gets on due to the incomplete shift in gears. This may damage the engine, and the 4WD service light will keep flashing permanently. To prevent this, you need to shift completely before driving. If you have moved into gear, but the light is still on, you can visit 4wd service Adelaide to detect other issues such as transmission problems, etc.

Programming issue
