STARTING SYSTEM (WITH INTELLIGENT KEY): System Description

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 met, the IPDM E/R will turn the starter control relay ON by starter control relay control signal.
When engine cranking condition is met, 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.
