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 under 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.

Component Function Check

INFOID:0000000006037462

1.

INSPECTION START

Turn ignition switch to START.
Is any cylinder ignited?

YES

>> GO TO 2.

NO

>> Go to 

EC-483, "Diagnosis Procedure"

.

2.

CHECK FUEL INJECTOR FUNCTION

With CONSULT-III

1.

Start engine.

2.

Perform “POWER BALANCE” in “ACTIVE TEST” mode with CONSULT-III.

3.

Make sure that each circuit produces a momentary engine speed drop.

Without CONSULT-III

1.

Let engine idle.

2.

Listen to each fuel injector operating sound.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Go to 

EC-483, "Diagnosis Procedure"

Diagnosis Procedure

INFOID:0000000006037463

1.

CHECK FUEL INJECTOR POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect fuel injector harness connector.

3.

Turn ignition switch ON.

4.

Check the voltage between fuel injector harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

DETECT MALFUNCTIONING PART
