Electronic Control System
PCM receives information from various input devices and uses this information to control solenoids on transaxle valve body for transaxle shifting, shift feel and torque converter clutch engagement. PCM automatically switches from NORMAL mode to POWER mode corresponding to driving condition in "D" range. Upshifts and downshifts are performed at a higher speed in POWER mode than in NORMAL mode.
PCM monitors transaxle operation and contains a self-diagnostic system which stores a DTC if an electronic control system failure or component malfunction exists. If a problem exists in any of the solenoids or speed sensors and DTC is set, PCM will deliver a signal to flash O/D OFF indicator light on instrument panel to warn the driver. DTC may be set if a failure exists and can be retrieved for transaxle diagnosis.
PCM contains a self-diagnostic system, which will store DTCs if a failure or problem exists in electronic control system. DTC can be retrieved to determine problem area. See RETRIEVING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM. PCM is located under right side of instrument panel, behind glove compartment.
