Chrysler Dodge Plymouth Trouble Codes and Retrieval Method

Most Chrysler, Dodge and Plymouth automobiles have a diagnostic trouble code retrieval method, Unlike Gm and Ford cars the Chrysler line of cars has no data port connector to gather codes from. Instead Chrysler has a ignition cycle activation sequence that anyone can active by turning the ignition key on off in rapid succession five times with the cycle ending in the "on" position. Once this activation has started the check engine light will start to flash. The first set of check engine light flashes will be the first digit of the two number code.

After the check engine light pauses for a short time it will start to blink again starting the second digit identification and completing the code's second number. If additional trouble codes are stored in the computer the first digit will begin to flash, and then the second digit. For example: the check engine light flashes four times, pauses and then flashes three more times the code is 43. The check engine light will flash one and then two meaning the code gathering is over. The system will only flash 12 if there are no codes stored in the computer's memory. To clear codes disconnect the negative battery terminal for 30 seconds and reconnect.
