DTC P0700: EATX Controller DTC Present

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For circuit identification and wiring diagram, see GRAND CHEROKEE wiring diagram in WIRING DIAGRAMS article.
NOTE: DTC P0700: EATX CONTROLLER DTC PRESENT is monitored with ignition on. DTC may be stored in Powertrain Control Module (PCM) if PCM senses any DTCs set in Transmission Control Module (TCM). Possible cause is: transmission DTC is present in PCM.

Turn ignition on, with engine off. Using scan tool, read DTCs. If DTC P0700: EATX CONTROLLER DTC PRESENT is set, this DTC indicates a transmission DTC has previously been set. A DTC may not currently be present in TCM if a transmission repair was performed. If after reading transmission DTCs there are no DTCs in TCM, this DTC may be erased from PCM. If a TCM DTC is present, see appropriate TRANSMISSION SERVICE & REPAIR article. Perform TEST VER-1A. If no TCM DTCs are present, test is complete.
