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 11.
