PROCEDURE


  1. READ VALUE USING GTS (FUEL INPUT)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Combination Meter / Data List.

    5. Check the values by referring to the table below.

  3. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SUCTION TUBE WITH PUMP AND GAUGE ASSEMBLY)


    1. Disconnect the P7 fuel suction tube with pump and gauge assembly connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      H14-26 (FR) - P7-2 (FS) Always Below 1 Ω
      H14-26 (FR) - Body ground Always 10 kΩ or higher
      H14-27 (FE) - P7-3 (FE) Always Below 1 Ω
      H14-27 (FE) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

    2. Check that the float moves smoothly between E and F.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 Float level is F (upper) 13.5 to 16.5 Ω
      1 - 2 Float level is between F (upper) and E (lower) 13.5 to 414.5 Ω (Gradually changes)
      1 - 2 Float level is E (lower) 405.5 to 414.5 Ω
