They'll check the CEL codes for free but the AT codes are a different matter. AT codes are not read by the OBDII port.Originally Posted by VXorado
You have to try harder than that...
You need to check the codes and look them up in the service manual. Most auto part stores will check codes for free.
It's not that difficult to read them & if you can't find the write-up let us know. IIRC it was in a thread started by deermagnet.
