SYSTEM DESCRIPTION

CVT Models

• “B” terminal is constantly supplied with battery power*.
• When selector lever is P or N, power is supplied to starter control relay by transmission range switch.
• When starter operating condition is satisfied, IPDM E/R turns starter relay ON by starter relay control signal.
• When engine cranking condition is satisfied, BCM turns starter control relay ON by starter control relay con-

trol signal.

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

M/T Models

• “B” terminal is constantly supplied with battery power*.
• When starter operating condition is satisfied, IPDM E/R turns starter relay ON by starter relay control signal.
