resetting the ECU

stangman16 · Feb 3, 2007

How do you reset the A9L computer? I did a search and read that you simply disconnected the battery, which I did for about 15 mins. I checked the codes again and I'm getting the exact same one's after I reconnect the battery and check the codes before cranking.

see: http://forums.stangnet.com/showthread.php?t=682454 for which code's i'm getting.

I replaced the MAP sensor and I'm still getting a code 22.

The computer has capacitors which retain some trace amounts of juice after a battery disconnect. Those capacitors need to be depleted to clear the 'memory'. The common method is to disco' the battery and then step on the brake pedal for a few seconds. The stop lights create a draw which wipes out the capacitors. If you dont create a draw (brake lights, headlights, etc) after disco'ing the battery, you will have to let the car sit with the battery disconnected for a fair amount of time.

Good luck.
