Powertrain Control Module (Pcm)
The PCM receives information from various input devices and uses this information to control both solenoids on transaxle valve body for transaxle shifting.
The PCM contains a self-diagnostic system, which will store a Diagnostic Trouble Code (DTC) if a failure is detected in the electronic control system. DTCs can be retrieved to determine problem area. See SELF-DIAGNOSTIC SYSTEM .
