P0773

CIRCUIT DESCRIPTION
The amount of current flow to the solenoid is controlled by the (*) duty ratio of the ECM output signal. The higher the duty ratio be- comes, 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
(*)
Duty Ratio = A / A+B * 100 (%)
