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