DTC CONFIRMATION PROCEDURE
1.CONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm battery voltage is more than 11 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-298, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
Is the inspection result normal?
YES-1 ( With CONSULT)>>GO TO 4.
YES-2 ( Without CONSULT)>>GO
TO 5.
NO >> Repair or replace error-detected parts.
3.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE GROUND CIRCUIT
Is the inspection result normal?
YES-1 ( With CONSULT)>>GO TO 4.
YES-2 ( Without CONSULT)>>GO TO 5.
NO >> Repair or replace error-detected parts.
4.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION
With CONSULT
Does engine speed vary according to the valve opening? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> GO TO 5.
5.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
Check the EVAP canister purge volume control solenoid valve. Refer to EC-300, "Component Inspection (EVAP Canister Purge Volume Control Solenoid Valve)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace EVAP canister purge volume control solenoid valve. Refer to EM-27, "Exploded View".

Is the inspection result normal? YES >> INSPECTION END
NO >> Replace EVAP canister purge volume control solenoid valve. Refer to EM-27, "Exploded View".
P1652 Starter motor system comm
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:
