1.CHECK EVAP CANISTER VENT CONTROL VALVE-I
1. Turn ignition switch OFF.
2. Remove EVAP canister vent c ontrol valve from EVAP canister.
3. Check portion (A) of EVAP canister vent control valve for being rusted.
Is it rusted?
YES >> Replace EVAP canister vent control valve. Refer to FL-
17, "Removal and Installation".
NO >> GO TO 2.
2.CHECK EVAP CANISTER VENT CONTROL VALVE-II
With CONSULT
1. Reconnect harness connectors disconnected.
2. Turn ignition switch ON.
3. Perform “VENT CONTROL/V” in “ACTIVE TEST” mode of “ENGINE” using CONSULT.
4. Check air passage continuity and operation delay time. Make sure new O-ring is installed properly.
Operation takes less than 1 second.
Without CONSULT
Check air passage continuity and operation delay time under the fol-
lowing conditions.
Make sure new O-ring is installed properly.
Operation takes less than 1 second.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace EVAP canister vent control valve. Refer to FL-17, "
Removal and Installation".
3.CHECK EVAP CANISTER VENT CONTROL VALVE-III
With CONSULT
1. Clean the air passage [portion (A) to (B)] of EVAP canister vent control valve using an air blower.
2. Perform “VENT CONTROL/V” in “ACTIVE TEST” mode of “ENGINE” using CONSULT.
