She couldn’t get it to operate thereafter. I discovered that four-Lo labored whilst in neutral, but when I picked 4-Hello I’d listen to the relay click on inside the TCCM, the LED on the switch would flash on, but then it will drop by 2WD.
So, you’re expressing the lights Never flash when trying to have interaction 4Hi? That’s slightly distinctive, with a couple far more small things to examine because the lights must flash If your TCCM is obtaining the signal.

Loosen the lock nuts. Concerning the tie rod and each tie rod stop can be a nut that retains it set up. You'll have to loosen this nut using a wrench. Bear in mind that on some vehicles, the driver's side lock nut could be threaded counterclockwise, though the passenger side is threaded clockwise.
Should you listen to clicking going into 4Lo, but not coming out (to 2Hi or 4Hi), then You may additionally Have got a terrible relay while in the TCCM.

The gray with black stripe wire (GRY/BLK) at pin five may be the 4Hi sign wire — when urgent the 4Hi button, this wire need to go sizzling (I haven’t examination the wire, so I’m undecided if it’s using logic ranges (+5VDC) or battery electricity (+12VDC) — In any event, it should be warm once the button is pressed.
How to tell When the TCCM is bad? Perfectly, that’s somewhat too associated for me to depth right here (fundamentally, it will involve systematic screening of the varied wires). If you can study a schematic, Then you definately’ll know what to do with it — all schematics that you choose to’ll need to have are in publish 1 of this thread.
I don’t have all the terminology, or know what many of the pieces are — but I may help you While using the routing from the lines!
