Toyota Corolla (E120): Circuit description

The actuator motor is operated by signals from the cruise control ecu assy. Acceleration and deceleration signals are transmitted by changes in the duty ratio (see below).

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
