12) Check “FUEL LEVEL SE” output voltage and confirm whether
the voltage changes more than 0.03V during step 7 to 11.

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-56.
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 69 (fuel level
sensor signal) and ground.
7) Turn ignition switch “ON”.
8) Check voltage between ECM terminal 69 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 69 and ground
changes more than 0.03V during step8-10.
If NG, check component of fuel level sensor, refer to EL-129,
“FUEL LEVEL SENSOR UNIT CHECK”.
