Can codes be pulled from Pettit ECU?
 

I want to take my car to the dealer to see if they can pull any codes from my ECU... but its a Pettit and I was wondering if anybody knows if there is any problem with that. Thanks

Somebody has to have a Pettit ECU don't they??

DOH! Not yet. Mine is suppose to hit the doorstep any day now... :rolleyes:

if you mean error codes, yes you still can check the same way, you can check yourself with a paper clip, if you don't know how let us know

yes I do mean error codes... Awesome, paper clips are always ceaper than a trip to the dealer!!:) Do you think you can tell me how to do the trick.. I have the manual that tells me what the codes mean, jsut don't know which holes to put the clip in. Thanks

You can use wire too:


With engine OFF, short "TEN" to "GND" terminals in the diagnostic plug (located on LH engine bay wheel well near battery). There is a "map" of the plug terminals located inside the plug lid.

Turn the ignition switch ON, but do not start the engine.

Read any stored trouble codes on the Check Engine light. If no codes are stored, the light will come on for approx. 2 seconds, then go out. If code(s) are stored, the Check Engine light will flash as follows to indicate code number. A Long flash represents the tens digit (10, 20, 30, etc.), and a short flash represents the ones digit (1 thru 9). Example: Long, short, short flash represents code 12. If any trouble codes are found, refer to page F-22 of the Workshop Manual for trouble shooting details.

Cancel any stored trouble codes by turning OFF the ignition and disconnecting the negative battery cable for 20+ seconds. Press the brake pedal. Reconnect the negative cable to the battery. Ref. page F-64 of the Workshop Manual).
