So as I turned my car on today and drove, the service 4wd light turned on and it stayed on the message dock. When I got to Oreilys, I took off the negative connection which was simple and then I connected it again. Should I have done both? When I turned the car back on, the message went away. I've never used the 4wd option. I've moved the knob but have always put it back to normal. The message isn't there anymore, I'm guessing that did the trick. I also bought a KN air filter to replace the stock one.

No. Just disconnect the negative lead. With one disconnected there is no path for current to flow from the battery to any components/computers. The negative lead is the one recommended to be disconnected if only removing one (or first, if disconnecting both). This is a safety measure. If you attempt to disconnect the positive lead from the battery first and accidentally short your wrench between the positive terminal and any exposed metal - you will get a large and powerful arc. By disconnecting the negative lead first (or only) the exposed metal of the vehicle will be at the same potential (same voltage) as the positive terminal. The only danger of the electrical arc at that point is if you actually short out the battery posts with your wrench.

It cost him a spanner to undo a 10mm nut on the battery terminal as the issue was the onboard computer (for want of an easy word) getting reset just the same as your domestic PC when it plays up and you use Ctrl+Alt+Del. (y)(y)

Just had this happen to me at about 11,000 miles. close inspection of the connector going to the rear 4wd actuator showed damaged insulation on one wire. I could make the fault appear/disappear by moving that wire. waiting for a replacement connector for the repair since it was very close to the connector housing.

Kenny I hope this thought may assist you. I recently was the type of novice that would try anything and everything in order to squash and attach any connector to a wire with whatever I could if the cable was not able to be removed from the vehicle, boat etc.

If I could get it disconnected I would try, mole grips, brick and a hammer etc.

Then, 2 years ago I heard that the young mechanics using a caravan beside me were using a fancy gadget to attach terminals to their cables. I asked what it was, watched it in action and then tried it on my battery connections. I was hooked and had to buy one for myself. Others have since used it and all are equally quick to praise it.

I am now a convert to a hand hydraulic crimper with different attachments for different diameters of connections. Have a look at this link and scroll down to the one around £21 but keep in mind this is a UK website. Just copy and paste the item description into your US equaivalent:

Hand hydraulic crimper

Then again having not researched your connector and knowing my luck it's likely to be a plug :cry::cry:

I have been of roading quite a bit in rough conditions and never had a light come on. Just curious if anyone knows what 4wd "service" would be preformed if the light coming on was for real?? Computers and their chips🤨 seems like they can create problems even when they don't exist.
