code 55 is to let you know when all of the codes have been read. also called end of sequence. If this is the only code you get, this means you have no problems
Code 43 refers to the coil. Code 55 is end of message.
it is the completion of the codes
55 is end of message. It just means that the test is done and there are no more codes.
the 12 is a pcm disconnect code can happen if the battery has been disconnected and hasn't had 50 key on cycles since...the 55 is an end of message code
55 is end of message. If that is the only code you have, then there isn't a problem
it means end of codes is all 55
It's not a code ,it's the start of the diagnostic programn.codes follow ,then 55 to end code reading.
Code 55 is end of message ( it is done flashing codes )Code 12 is start of message or battery was disconnected.Code 55 is end of message ( it is done flashing codes )Code 12 is start of message or battery was disconnected.
The code 12 on a 1996 Plymouth Voyager indicates the battery was disconnected within the last 50 key cycles. The codes 54 and 55 relate to issues with the camshaft sensor or camshaft-related components.
Code 55 means there are no codes stored in the computer memory. I have owned a 1988 Full size van, a 1988 Plymouth carravelle and currently own 1994 Chrysler Town and Country. When you run your key cycle codes if there are none stored, it will flash 55 to let you know that it has no more codes. Of course if their are codes it will flash them in numerical order. (with the exceotion of codes above 55, yes therer are a few.) it will flash the codes above 55 and then flash code 55. Example, Codes: 12 (speed sensor), 17 (engine cold to long), 61 (Baro circuit Shorted), 55 (end of codes) sometimes you may even get a code 88 (start of test codes). So what you have at code 55 is a perfect code free computer.
End of message, no more codes.
Trouble code 55 on a 1991 Plymouth Acclaim indicates that the engine control module (ECM) has completed its self-diagnostic tests and found no faults. This code is often referred to as a "completion code," signaling that the system is functioning normally. It typically appears after running the diagnostic test and is not indicative of any specific issue. If you're troubleshooting, it's a sign that there are no stored fault codes in the system at that time.
