(10) Air Valve
NOTE
• Check the actuation of air valve 1 and 2 before following checking.
1. Remove the double flare pipes from air valve 1 and 2 outlet.
2. Do active test "All Devices for Fuel Reformer Operate Function" by using diagmaster, then check if
the air comes out from air valve outlet (Refer to "Diagnosis Manual V1505-T-E4 (9Y120-02490)").
• It is possible to check the continuity of Yellow / Green wire by using active test "Air Valve 1 for Fuel
Reformer Operate Function".
• It is possible to check the continuity of White / Green wire by using active test "Air Valve 2 for Fuel
Reformer Operate Function".
