NOTE: ACTINON is 12VDC from ECU and is active only when the ECU is controlling the actuator!
Actuator Interface
The Actuator Interface Module contains several relays that control the Linear Actuator. One
important function is the Mechanical Force to Idle on Park Brake Loss.
The ACTINON signal is a pulsed 12 VDC from the ECU. It is only present when the ECU is
actively positioning the actuator.
ACTDIRA and ACTDIRB are the Ignition and Ground feed to the actuator motor, direction is
controlled by the polarity on this pair of wires.
ACTOUT controls the direction of the actuator motor, when active the motor will move the
throttle toward its idle position.
