P1651 STARTER MOTOR RELAY

Description

INFOID:0000000006548528

ECM controls ON/OFF state of the starter relay, according to the engine and vehicle condition. Models with no
Intelligent Key System transmit a control signal directly to IPDM E/R. On the other hand, models with the Intel-
ligent 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.
