5) Turn ignition switch “OFF” and wait at least 5 seconds then
turn “ON”.
6) Select “FUEL LEVEL SE” in “DATA MONITOR” mode with
CONSULT-II.
7) Check “FUEL LEVEL SE” output voltage and note it.
8) Select “FUEL PUMP” in “ACTIVE TEST” mode with CON-
SULT-II.
9) Touch “ON” and drain fuel approximately 30 (7-7/8 US gal,
6-5/8 Imp gal) and stop it.
10) Fill fuel into the fuel tank for 30 (7-7/8 US gal, 6-5/8 Imp gal).
11) Check “FUEL LEVEL SE” output voltage and note it.
12) Check “FUEL LEVEL SE” output voltage and confirm whether
the voltage changes more than 0.03V during step 7 to 11.
If NG, check the fuel level sensor, refer to EL-87, “FUELLEVEL
SENSOR UNIT CHECK”.

NOTE:
Start from step 11, if it is possible to confirm that the fuel
cannot be drained by 30 (7-7/8 US gal, 6-5/8 Imp gal) in
advance.
1) Prepare a fuel container and a spare hose.
2) Release fuel pressure from fuel line, refer to “Fuel Pressure
Release”, EC-637.
3) Remove the fuel feed hose on the fuel level sensor unit.
4) Connect a spare fuel hose where the fuel feed hose was
removed.
5) Turn ignition switch “OFF”.
6) Set voltmeters probe between ECM terminal 46 (fuel level
sensor signal) and ground.
7) Turn ignition switch “ON”.
8) Check voltage between ECM terminal 46 and ground and note
it.
9) Drain fuel by 30 (7-7/8 US gal, 6-5/8 Imp gal) from the fuel
tank using proper equipment.
10) Fill fuel into the fuel tank for 30 (7-7/8 US gal, 6-5/8 Imp gal).
11) Confirm that the voltage between ECM terminal 46 and ground
changes more than 0.03V during step8-10.
If NG, check component of fuel level sensor, refer to EL-87,
“FUEL LEVEL SENSOR UNIT CHECK”.
