Circuit Description
WARNING: This page is about a different variant/trim than selected.
The amount of current flowing to the solenoid is controlled by the duty ration of the engine control module (ECM) output signal. The higher the duty ratio becomes, the higher the lock-up hydraulic pressure becomes during the lock-up operation.
When an open or short in the shift solenoid valve SLU circuit is detected, the ECM interprets this as a fault. The ECM will turn on the MIL and store the DTC.
