Chrysler Fault Codes

Comment comment by VnutZ on 13 May 2007

Most Jeep owners are familiar with this trick ... but it works for most Chrysler vehicles. From the website http://www.allpar.com/fix/codes.html:

Normally, to get codes, you put the key on OFF and then rapidly do OFF-ON-OFF-ON-OFF-ON (on some cars you have to do four or five, not three, OFF-ON cycles). On our test 2002 car, the key did not go back to unlock, so it was ACC-ON-ACC-ON-ACC-ON.

To clear the codes, you still generally need a scan reader to send an acknowledgment command to the ECU. Resetting an ECU is typically a matter of disconnecting the vehicle's battery and then grounding the positive terminal (to discharge the ECU). If the problem is systemic - it will come back, unless cleared by OBD acknowledgment.

Honda accord by Anonymous :: NR0

its funny how many people dont open up the user manual of their cars.

i had this same problem, opened up the manual the car came with, and there you go, detailed instructions that worked lol, but it is good to check the car out every so often to make sure, rotations, oil change, air filter, spark plugs, etc.
