Description
ECM controls ON/OFF state of the starter relay, according to the engine and vehicle condition. ECM transmits a control signal to IPDM E/R via BCM by CAN communication.
Under normal conditions, ECM controls and maintains the starter relay in OFF state during following condition:
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.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION
Is DTC detected? YES >> Proceed to EC-404, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK SELF-DIAGNOSTIC RESULT IN BCM
With CONSULT
Check self-diagnostic result in BCM.
Are any DTC detected? YES >> Check the DTC. Refer to BCS-49, "DTC Index" (with intelligent key), BCS-109, "DTC Index" (without intelligent key).
NO >> GO TO 2.
2.CHECK SELF-DIAGNOSTIC RESULT IN IPDM E/R
With CONSULT
Check self-diagnostic result in IPDM E/R.
Are any DTC detected? YES >> Check the DTC. Refer to PCS-20, "DTC Index" (with intelligent key), PCS-48, "DTC Index" (without intelligent key).
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE
Is the P1652 displayed again? YES >> GO TO 4.
NO >> INSPECTION END
4.CHECK INTERMITTENT INCIDENT
Check intermittent incident. Refer to GI-39, "Intermittent Incident".
Is the inspection result normal? YES >> Replace IPDM E/R. Refer to PCS-58, "Removal and Installation".
NG >> Repair or replace error-detected parts.
