MOR
Each Electric Displacement Control (EDC) is equipped with a Manual Over Ride (MOR) function for
temporary actuation of the control to aid in diagnostics, even if insufficient or no current is supplied to
the solenoid actuator. Initial activation of the MOR function will require a higher force to overcome the
sticking effect between the pin and O-ring seal. Repeated activation of this functionality should provide
better controllability.
