P1650 STARTER MOTOR RELAY 2
Description
INFOID:0000000007577303
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.

P1651 STARTER MOTOR RELAY
P1651 STARTER MOTOR RELAY
Description
INFOID:0000000007577306
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.

STR MTR RELAY
(Starter control relay circuit)
A correlated error is detected for 2 sec-
onds or more between a control signal
transmitted from ECM and a feedback sig-
nal transmitted from IPDM E/R via CAN
communication line.
• Harness or connectors
(Between ECM harness connector and
IPDM E/R harness connector is short-
ed to power.)
(Between ECM harness connector and
BCM harness connector is shorted to
power.)

Diagnosis Procedure
INFOID:0000000007577308
1.
INSPECTION START
Check the starter motor operation.
Is the starter motor operated?
YES
>> GO TO 3.
NO
>> GO TO 2.
2.
CHECK DTC WITH IPDM E/R
Check DTC with IPDM E/R. Refer to
PCS-13, "CONSULT Function (IPDM E/R)"
Is the inspection result normal?
YES-1 >> With Intelligent Key system: GO TO 3.
YES-2 >> Without Intelligent Key system: GO TO 6.
NO
>> Perform trouble diagnosis for DTC indicated.
3.
CHECK DTC WITH BCM
Check DTC with BCM. Refer to
BCS-29, "BCM : CONSULT Function (BCM - BCM)"
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Perform trouble diagnosis for DTC indicated.
4.
CHECK CRANKING REQUEST SIGNAL CIRCUIT-I
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Disconnect IPDM E/R harness connector.
4.
Check the continuity between ECM harness connector and IPDM E/R harness connector.
5.
Also check harness for short to ground to power.
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> Repair or replace error-detected parts.
5.
CHECK CRANKING REQUEST SIGNAL CIRCUIT-II
1.
Disconnect BCM harness connector.
2.
Check the continuity between ECM harness connector and BCM harness connector.
3.
Also check harness for short to ground to power.
Is the inspection result normal?
YES
>> GO TO 7.
NO
>> Repair or replace error-detected parts.
6.
CHECK CRANKING REQUEST SIGNAL CIRCUIT-III
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Disconnect IPDM E/R harness connector.
4.
Check the continuity between ECM harness connector and IPDM E/R harness connector.
