Transmission Control Module (TCM)

The Transmission Control Module (TCM) receives information from various input devices and uses this information to control shift and lock-up control solenoid valves. See Figure . The TCM contains a self-diagnostic system which stores Diagnostic Trouble Codes (DTC) information if a failure or problem exists in the transaxle electronic control or the fuel injection system. DTC or Flash Code can be retrieved to determine transaxle problem area. For information on self-diagnostic system, see SELF-DIAGNOSTIC SYSTEM  . The TCM is located under carpet on passenger's footwell.
