I've seen this thread before and printed out the manual but I would like the instructions in regular terms. I am a decent mechanic but electrical work I leave to the pros. Anyone have a step by step instruction. MKIV.com is down. Any help would be appreciated!! Alex 93tt6dp hardtopper.

Get two pieces of thin wire a couple feet long. Strip the ends so you have bear wire. Insert the end of one wire in the Tc terminal of the diag port. Insert the end of the other wire in the AB terminal of the diag port. Turn ignition to On or ACC (don't start).

Get the other ends of the wire, one in each hand. You are going to alternate touching the ends of the wire to a ground (any bear metal body spot). I use one of the shock studs sticking up on the passenger side. Each touch needs to be held for 1 second and when you switch do so immediately with no more than .2 seconds in between switching. Sequence goes like this:

Tc- 1 sec
AB- 1 sec
Tc- 1 sec
AB- 1 sec
Tc- hold the Tc to ground for a few seconds.

ABS light should blink really fast now showing that the codes cleared.

Thanks for the gracious information!!! The supraforums to the rescue again. One question: I read some other stuff , so I don't need to mess with the battery at all? I'll try this tomorrow!! Alex 93tt 6spd hardtopper.....a little banged up but ready for a paint job!!

Don't need to mess with the battery. Some people might run the wires over to the negative terminal to get the needed ground but it's not necessary. The negative terminal of the battery attaches to the body of the car, so any body part that is bear metal is good also. The body of the car is really like one big wire with the neg battery terminal connected to it. I remember just using the shock tower studs. If that doesn't work then maybe the engine hook on that side.

After reading again I have it figures out. I will try this tomorrow when I get back to work. I have plenty of tools and wire there. Thanks a million!!! Alex 93tt6spd hardtopper
