(DTC) CODE P0700 - Transmission Control System (MIL Request) Translation: Transmission Control Module (TCM) Malfunction or Failure. P0700 Information Code The Transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. If any malfunction is detected, the TCM informs the PCM by sending a signal (P0700 code). P0700 means that a code has been set in the TCM. This code is for information ONLY. If this code is present, check for transaxle codes. So basically, the P0700 code is telling you to check the TCM for a transaxle DTC. The TCM can cannot turn on the check engine light so it has the PCM do it, which can only be done with a diagnostic scanner. The self retrieval method for Chryslers with the ignition key will not pull up the specific transmission fault codes in the TCM.
