Hello,

I repaired the ABS in my 93 Wagon right after I purchased it used.

I have the factory manual.Please email for more info or a fax copy of a few pages.

Here goes. The ABS computer is like the ECM . You connect terminal H in the DLC connector under the dash to ground . Terminal H is in the lower row, second from left. Turn the ignition to run. after 3 seconds the ABS Light will flash codes. Three codes 12's will flash. Then the trouble codes will flash. Then three more 12's will flash. Don't forget to remove the jumper.

Email me or post your codes.

Good luck.

Scott

I think he means the ALDL connector.

The factory manual refers to the DLC. I would call it the ALDL also.
