4WD Light

[Nick Fletcher]

Hey everyone,

 

I am having an issue with my 4WD light.

 

It's not so much the 4WD . It will engage in 4 wheel hi and low, and disengage but the 4WD engaged light never goes out.

 

I tried hooking this up to a scanner to check for error codes and there are none.

 

I have been reading through a few forums and found it might be the front differential actuator? I am wondering if this is the most likely cause of this problem and if there is a way to test it to make sure it is the issue before I buy the parts because it looks like a fairly easy fix if it is.

 

Thanks

 

Nick

An inexpensive scanner will only pull engine codes.

 

You need a scanner that can access the control module for the 4WD system to pull 4WD diagnostic codes.

 

Chat up a garage or two, and see if they will check the codes for you.
