Electronic Control Module

ECM receives information from various input devices and uses this information to control No. 1 and No. 2 shift solenoids on transaxle valve body for transaxle shifting and SL solenoid for TCC lock-up. ECM contains a self-diagnostic system, which will store a DTC if a failure or malfunction exists in electronic control system. DTCs can be retrieved to determine problem area. See DIAGNOSIS & TESTING . Note location of ECM. See Figure.
