Starter Control Relay

Engine starting system functions by controlling both starter relay and starter control relay.
Both relays are integrated in IPDM E/R. Starter relay is controlled by BCM, and starter control relay is controlled by IPDM E/R on request from BCM.
IPDM E/R transmits starter relay and starter control relay status signal to BCM via CAN communication.
During engine is running, starter control relay is controlled by IPDM E/R according to the cranking request signal from ECM for Stop/Start System.
