Powertrain Control Module

Transaxle shifting and torque converter lock-up are controlled by PCM. PCM is located below instrument panel under front lower panel in center console area. See Figure. PCM receives information from various input devices and uses this information to control shift, A/T clutch pressure control solenoid valves and lock-up control solenoid valves.

PCM contains a self-diagnostic system which stores a trouble code if a failure is present in transaxle electronic control system. Trouble code may be retrieved as a DTC (4 digits) or flash code (1 or 2 digits) to determine transaxle problem area. See SELF-DIAGNOSTIC SYSTEM .
