• When the clutch interlock switch is turned ON, power is supplied to starter control relay. And IPDM E/R

(CPU) detect clutch interlock switch condition by the inputted signal.

• When starter operating condition is satisfied, IPDM E/R turns starter control relay ON by starter control relay

control signal.

• When engine cranking condition is satisfied, then battery power is supplied to starter motor (“S” terminal)

through starter control relay.
