• When the selector lever is in the P or N position, power is supplied to starter relay and starter control relay by

the transmission range switch. The BCM and IPDM E/R (CPU) will detect the selector lever position by the

input signal.

• When the starter operating condition is meet, the IPDM E/R will turn the starter control relay ON by starter

control relay control signal.

• When engine cranking condition is meet, the BCM turns ON the starter relay by starter control relay signal.

• Then battery power is supplied to starter motor (“S” terminal) through the starter control relay and starter

relay.
