System Description

INFOID:0000000006275521

• When selector lever is P or N, power is supplied to starter relay and starter control relay by TCM. And BCM

and IPDM E/R (CPU) detect selector lever P/N 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, BCM turns starter relay ON by starter relay control signal.
• Then battery power is supplied to starter motor (“S” terminal) through starter control relay and starter relay.

And IPDM E/R (CPU) detect starter relay condition by the inputted signal.
