I just moved the vehicle from in front of my garage to the grass to get my car out, moving the explorer back after, just about 25 feet the 'terrain management system fault' indicator came on. I suspect rodents? or squirrels may have had a meal on some wires since the car was moved very little.
Any help?
Thanks Carmen

It could be the rodents are brutal on wiring but to be sure we need to scan the system for codes which you can do easily, check out this video which will show you how. I have also seen one of the front bearing hubs go out causing the ABS sensor not to work which is common as well.

Let me know which code it is so I can help you fix it. I have included how to change out the front bearing hub just in case you need it. Once the bearing hub has been replaced the light should go off. I would do both sides. Check out the images (below). Please let us know what happens.

Thank you, I'll get the codes scanned, yesterday after driving the car to town, the warnings went away, then restarting the vehicle all the terrain management systems were back, no warnings, I'm glad but weary that is come and go - thanks for your reply.

Yep, it sounds like the hub bearing is just starting to go out, if you make a turn and the light comes on this is a good sign it is the hub bearings.
