Low fluid levels in the transfer case or differential

Low fluid levels in the transfer case or differential can cause the service 4WD light to illuminate. The transfer case is responsible for transferring power from the transmission to the front and rear axles, while the differential allows the wheels on each axle to turn at different speeds. If either of these components has low fluid levels, it can cause the 4WD system to malfunction, which can lead to the service 4WD light being illuminated.

It is important to check the fluid levels in the transfer case and differential regularly, especially if you are driving in off-road conditions. If the fluid levels are low, you should add the appropriate fluid until the reservoir is full. You can find the recommended fluid type and capacity in your vehicle’s owner’s manual.

If you are not comfortable checking the fluid levels yourself, you can take your vehicle to a qualified mechanic. They will be able to check the fluid levels and add the appropriate fluid if necessary.
