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.
