| I got the same code, but there was no CEL. From the discussion, we determined that the code meant that there were more codes. Do you have other codes from the AP? I had some ABS codes, but that might be from my new tire install. | ||||||||

| check your grounds, CAN is a very sensitive 5 volt hi low circut, check your ECM grounds clean and re-tighten them and see if it comes back, let me look up the diagnostic logic of the code and i'll tell you what it might be or its just a glitch from the piggyback. | ||||||||

| all this code means was the another code was thrown and the ecu requested that the CEL is turned on.....depending on the code it may take several key cycles to turn on. Or if the condition goes away u may never get a CEL
