Hi Eric, okay in the 90 FSM the procedure for clearing the codes is a six step process. Now I do not know if it is the same for the other model yrs.

I could not get the timing correct for the grounding for 3 seconds, ungrounding for three seconds of the "K" terminal on my 90. I got a bell push button at the hdw store and wired it into a length of telephone wire. I stuck one end in the "K" terminal and the other end I used an alligator clip to the seat chassis. If you push the bell button the system is now a complete circuit, grounded; release the button the circuit is opened. I used my watch's second hand to time the ground/unground periods because the FSM says it's +/- 1/2 second on a three second count.

The 90 procedure is:
1.) Ing "OFF"
2.) Ground "K" terminal. (Hold the door bell button)
3.) Turn Ing "ON".
4.) Wait for fault codes to begin flashing, takes about 5 seconds. When DTC's begin flashing, unground "K" for 3 seconds, +/- 1/2 seconds. ( finger off button for 3 seconds)
5.) Ground "K" for 3 seconds, + /- 1/2 seconds. ( push the bell button )
6.) Unground "K" and wait 10 seconds ( finger off button ). Before turning ING "off", verify that the only code is "12" being flashed ( push the bell button to see "12" ). If not repeat from step "1".
That's the book version for a 90. I tried without the mechanical aid & no joy. Once I red necked the door bell, I got it first shot. If you want to use a toggle switch it may be easier?
