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 A AND C
Is 1st trip DTC detected? YES >> Proceed to EC-400, "Diagnosis Procedure".
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B
With CONSULT
CAUTION:
Always drive at a safe speed.
Without CONSULT
CAUTION:
Always drive at a safe speed.
For M/T models: Fully release the clutch pedal.
Is 1st trip DTC detected? YES >> Proceed to EC-400, "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 PCS-20, "DTC Index" (with intelligent key), PCS-48, "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 BCS-49, "DTC Index" (with intelligent key), BCS-109, "DTC Index" (without intelligent key).
NO >> GO TO 3.
3.CHECK STARTER RELAY POWER SUPPLY CIRCUIT
Check the starter motor relay power supply circuit. Refer to PCS-29, "Diagnosis Procedure" (with intelligent key), or PCS-57, "Diagnosis Procedure" (without intelligent key).
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK STARTER RELAY CONTROL SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.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.
Rapid air pressure loss
Rapid air pressure loss or a “blow-out” can occur
if the tire is punctured or is damaged due to
hitting a curb or pothole. Rapid air pressure loss
can also be caused by driving on under-inflated
tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially ...
If you have a flat tire
Your vehicle is equipped with a spare tire. The flat tire can be
replaced with the spare tire.
WARNING
■If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair, which could result in an ...
