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 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.

NOTE:
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P1651 | STR MTR RELAY (Starter motor relay) | A correlated error is detected for 2 seconds or more between a control signal transmitted from ECM and a feedback signal transmitted from IPDM E/R via CAN communication line. |

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 1st trip DTC detected? YES >> Proceed to EC-402, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
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-10, "CONSULT Function (IPDM E/R)" (with intelligent key), or PCS- 38, "CONSULT Function (IPDM E/R)" (without intelligent key).
Is the inspection result normal? YES >> GO TO 3.
NO >> Perform trouble diagnosis for DTC indicated. Refer to PCS-20, "DTC Index" (with intelligent key), or PCS-48, "DTC Index" (without intelligent key).
3.CHECK CRANKING REQUEST SIGNAL CIRCUIT-1
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
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-30, "Removal and Installation".
NO >> Repair or replace error-detected parts.
