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.
On Board Diagnostic (OBD) System of Engine and CVT
The ECM has an on board diagnostic system. It will light up the malfunction
indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
Be sure to turn the ignition switch OFF and disconnect the
negative battery cable before any repair
or inspection ...
