So I was driving down to Raleigh to get my Rock rails installed by Carolina Rock Shop. About 2 hours into the drive (3 hour drive) my speedometer went crazy! I was cruising at 70mph and all of the sudden the cruise control stopped working and the e-brake light went on (it was not engaged at all). My odometer is not regestering any milage at all. I got to Raleigh and let the KJ sit overnight. When I started her back up, the speedometer worked. It worked for about 15-20 minutes (cruise control back on) and then the same thing happened again. Fast Foreward: On the drive back to Richmond from Raleigh, my tranny light was on the whole drive up. I stopped when it came on and felt the tranny to see if it was overheating. It seem to be at the normal temp so I figured it would be ok to drive to Richmond. I made it home and I really dont want to drive it much at all with all this going on. Does anyone know what the issue is?

I know it sounds funny but check your battery connections and main ground wire. Sometimes a weak connection can make the computer go crazy.

Check out this thread. My 02's speedo did the same wild fluctuating before it went dead altogether. Turns out Jeepin Al was correct -- the connector wires on top of the rear diff had chaffed through thanks to the e-brake line rubbing against it. I bought the re-wire kit (see thread for part number) and that fixed it!

Alright thanks for the replys. Now, when I was coming home from work today, the "Engine/Auto Tranny Malfunction" light came on. Any idea? I do have a homemade CAI with no MAF sensor. Could this be an issue? I tried to pull a code but nothing came up. This thing IS going to the stealership tomarro for a FULL diagnostics. ABS sensors are getting replaced, Speedo lines checked, malfunction light getting checked, BOTH ball joints. Anyone have an idea what else I should get them to check on that is a known issue with the 02 KJ?
