Transmission Control Module (TCM)
The TCM receives information from various input devices and uses this information to control shift, A/T clutch pressure and lock-up control solenoid valves. See Fig 1 . The TCM contains a self-diagnostic system which stores a fault code if a failure is present in transaxle electronic control system. Fault code may also be referred to as Diagnostic Trouble Code (DTC) or flash code. DTC or flash code may be retrieved to determine transaxle problem area. See SELF-DIAGNOSTIC SYSTEM . The TCM is located behind center of instrument panel. See Figure .
