Diagnostic Procedure
UBS00DDT
SYMPTOM: FUEL ODOR FROM EVAP CANISTER IS STRONG.
1.
CHECK EVAP CANISTER
1.
Remove EVAP canister with EVAP canister vent control valve attached.
2.
Weigh the EVAP canister with EVAP canister vent control valve attached.
The weight should be less than 1.8 kg (4.0 lb).
OK or NG
OK
>> GO TO 2.
NG
>> GO TO 3.
2.
CHECK IF EVAP CANISTER SATURATED WITH WATER
●
Does water drain from the EVAP canister?
Yes or No
Yes
>> GO TO 3.
No (With CONSULT-II)>>GO TO 6.
No (Without CONSULT-II)>>GO TO 7.
3.
REPLACE EVAP CANISTER
Replace EVAP canister with a new one.
>> GO TO 4.
4.
CHECK WATER SEPARATOR
1.
Check visually for insect nests in the water separator air inlet.
2.
Check visually for cracks or flaws in the appearance.
3.
Check visually for cracks or flaws in the hose.
4.
Check that A and C are not clogged by blowing air into B with
A , and then C plugged.
5.
In case of NG in items 2 - 4, replace the parts.
NOTE:
●
Do not disassemble water separator.
OK or NG
OK
>> GO TO 5.
NG
>> Replace water separator.
5.
DETECT MALFUNCTIONING PART
Check the EVAP hose between EVAP canister and water separator for clogging or poor connection.
>> Repair or replace EVAP hose.

6.
CHECK REFUELING EVAP VAPOR CUT VALVE
With CONSULT-II
1.
Remove fuel tank. Refer to
2.
Drain fuel from the tank as follows:
–
Remove fuel feed hose located on the fuel gauge retainer.
–
Connect a spare fuel hose, one side to fuel gauge retainer where the hose was removed and the other
side to a fuel container.
–
Drain fuel using “FUEL PUMP RELAY” in “ACTIVE TEST” mode with CONSULT-II.
3.
Check refueling EVAP vapor cut valve for being stuck to close as follows.
Blow air into the refueling EVAP vapor cut valve (from hose end B), and check that the air flows freely into
the tank.
4.
Check EVAP vapor cut valve for being stuck to open as follows.
–
Connect vacuum pump to hose ends A and B using a suitable 3-way connector.
–
Remove fuel gauge retainer with fuel gauge unit.
Always replace O-ring with new one.
–
Put fuel tank upside down.
–
Apply vacuum pressure to both hose ends A and B [
−13.3 kPa (−100 mmHg, −3.94 inHg)] with fuel gauge
retainer remaining open and check that the pressure is applicable.
OK or NG
OK
>> GO TO 8.
NG
>> Replace refueling EVAP vapor cut valve with fuel tank.

Remove fuel tank. Refer to
.
2.
Drain fuel from the tank as follows:
–
Remove fuel gauge retainer.
–
Drain fuel from the tank using a hand pump into a fuel container.
3.
Check refueling EVAP vapor cut valve for being stuck to close as follows.
Blow air into the refueling EVAP vapor cut valve (from hose end B), and check that the air flows freely into
the tank.
4.

8.
CHECK REFUELING CONTROL VALVE
1.
Remove fuel filler cap.
2.
Check air continuity between hose ends A and B.
Blow air into the hose end B. Air should flow freely into the fuel tank.
3.
Blow air into hose end A and check there is no leakage.
4.
Apply pressure to both hose ends A and B [20 kPa (150 mmHg, 5.91 inHg)] using a pressure pump and a
suitable 3-way connector. Check that there is no leakage.
OK or NG
OK
>> INSPECTION END.
NG
>> Replace refueling control valve with fuel tank.
SYMPTOM: CANNOT REFUEL/FUEL ODOR FROM THE FUEL FILLER OPENING IS STRONG
WHILE REFUELING.
