6.CHECK FOR EVAP LEAK
With CONSULT-III
1. Turn ignition switch ON.
2. Select “EVAP SYSTEM CLOSE” of “WORK SUPPORT” mode with CONSULT-III.
3. Touch “START” and apply pressure into the EVAP line until the pressure indicator reaches the middle of
the bar graph.
CAUTION:
Do not use compressed air or a high pressure pump.
Do not exceed 4.12 kPa (0.042 kg/cm
2, 0.6 psi) of pressure in the system.
4. Using EVAP leak detector, locate the EVAP leak. For the leak
detector, refer to the instruction manual for more details.
Refer to EC-618, "
Description".
OK or NG
OK >> GO TO 8.
NG >> Repair or replace.

EVAP canister vent control valve. Refer to EC-949, "
Component Inspection".
OK or NG
OK >> GO TO 9.
NG >> Repair or replace EVAP canister vent control valve and O-ring.
9.CHECK IF EVAP CANISTER SATURATED WITH WATER
1. Remove EVAP canister with EVAP canister vent c ontrol valve and EVAP control system pressure sensor
attached.
2. Does water drain from the EVAP canister?
Ye s o r N o
Yes >> GO TO 10.
No (With CONSULT-III)>>GO TO 12.
No (Without CONSULT-III)>>GO TO 13.
10.CHECK EVAP CANISTER
Weigh the EVAP canister with the EV AP canister vent control valve and EVAP control system pressure sensor
attached.
The weight should be less than 2.1 kg (4.6 lb).
