CIRCUIT DESCRIPTION



The amount of current flow to the solenoid is controlled by the (*) duty ratio 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.
(*) Duty Ratio:



- The duty ratio is the ratio of the period of continuity in one cycle.



- For example, if A is the period of continuity in one cycle, and B is the period of non-continuity, then
