Code P1D8A Honda Description
Occurrence of open in the gate drive-wire, the motor power cable line, or the MPI module (generator) OFF failure causes decrease in inflow or outflow of the current of the failed phase (inflow decreases in the event of High side open and outflow decreases in the event of Low side open) causing distortion of the current from the other two phases. As a result, the deviation between the target phase current and actual phase current increases significantly. Malfunction is detected according to deviation of the phase current.
