P1652 STARTER MOTOR SYSTEM COMM

Description

INFOID:0000000012198049

ECM controls ON/OFF state of the starter relay, according to the engine and vehicle condition. On the other

hand, models with the Intelligent Key System transmit a control signal to IPDM E/R by way of BCM via CAN

communication.

Under normal conditions, ECM controls and maintains the starter relay in OFF state during engine running or

“D” position. 

When detecting a decrease in engine speed due to rapid deceleration or heavy load condition, ECM controls

and reactivates the starter relay.

IPDM E/R detects a control state of starter relay and starter control relay and transmits a feedback signal to

ECM via CAN communication.
