Transmission Control Module

The Transmission Control Module (TCM) receives information from various input devices and uses this information to control linear solenoid, shift and lock-up control solenoid valves. See Figure. The TCM contains self-diagnostic system, which stores fault code if failure or problem exists 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 glove box and contains 26-pin and 22-pin Gray electrical connectors. See Figure.
