DTC CONFIRMATION PROCEDURE
1.CONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
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
1. Start engine and let it idle for at least 13 seconds.
2. Check 1st trip DTC.
Is 1st trip DTC detected? YES >> Proceed to EC-283, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect EVAP canister purge volume control solenoid valve harness connector.
3. Turn ignition switch ON.
4. Check the voltage between EVAP canister purge volume control solenoid valve harness connector and ground.
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
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R harness connector.
3. Check the continuity between EVAP canister purge volume control solenoid valve harness connector and IPDM E/R harness connector.
4. Also check harness for short to ground.
Is the inspection result normal? YES-1 >> With CONSULT-III: GO TO 4.
YES-2 >> Without CONSULT-III: GO TO 5.
NO >> Repair or replace error-detected parts.
3.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between EVAP canister purge volume control solenoid valve harness connector and ECM harness connector.
4. Also check harness for short to power.
Is the inspection result normal? YES-1 >> With CONSULT-III: GO TO 4.
YES-2 >> Without CONSULT-III: GO TO 5.
NO >> Repair or replace error-detected parts.
4.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION
With CONSULT-III
1. Reconnect all harness connectors disconnected.
2. Start engine.
3. Perform “PURG VOL CONT/V” in “ACTIVE TEST” mode of “ENGINE” using CONSULT-III.
4. Check that engine speed varies according to the valve opening.
Does engine speed vary according to the valve opening? YES >> Check intermittent incident. Refer to GI-42, "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-284, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
NO >> Replace EVAP canister purge volume control solenoid valve. Refer to EM-28, "Exploded View".
Component Inspection
1.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
With CONSULT-III
1. Turn ignition switch OFF.
2. Reconnect all harness connectors disconnected.
3. Disconnect EVAP purge hoses connected to EVAP canister purge volume control solenoid valve.
4. Turn ignition switch ON.
5. Select “PURG VOL CONT/V” in “ACTIVE TEST” mode of “ENGINE” using CONSULT-III.
6. Touch “Qd” and “Qu” on CONSULT-III screen to adjust “PURG VOL C/V” opening and check air passage continuity of EVAP canister purge volume control solenoid valve as per the following conditions.
Without CONSULT-III
1. Turn ignition switch OFF.
2. Disconnect EVAP canister purge volume control solenoid valve harness connector.
3. Disconnect EVAP purge hoses connected to EVAP canister purge volume control solenoid valve.
4. Check air passage continuity of EVAP canister purge volume control solenoid valve as per the following conditions.
YES >> INSPECTION END
NO >> Replace EVAP canister purge volume control solenoid valve. Refer to EM-28, "Exploded View".
