      Combination Meter
      Tester Display Test Part Control Range Diagnostic Note
      Fuel Meter Operation Fuel receiver gauge EMPTY, 1/2 or FULL Perform test with vehicle stopped and engine idling
      OK
      Needle indication is normal.

    NG

    REPLACE NO. 1 METER ECU Click here

    OK

  3. READ VALUE USING INTELLIGENT TESTER (FUEL INPUT)


    1. Operate the intelligent tester according to the display and select "Data List".

      Combination Meter
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Fuel Input Fuel sender gauge (main) input signal/Min.: 0, Max.: 127.5 Fuel sender input value Unit: L
      OK
      Fuel value displayed on tester is almost the same as needle indication.

    NG

    CHECK HARNESS AND CONNECTOR (REAR JUNCTION BLOCK ECU - FUEL SUCTION PLATE SUB-ASSEMBLY AND FUEL SENDER GAUGE [SUB]) Click here

    OK

    REPLACE NO. 1 METER ECU Click here

  4. CHECK HARNESS AND CONNECTOR (REAR JUNCTION BLOCK ECU - FUEL SUCTION PLATE SUB-ASSEMBLY AND FUEL SENDER GAUGE [SUB])

    A01GWOJE03

    1. Disconnect the S61 junction block connector.

    2. Disconnect the S11 suction plate connectors.

    3. Disconnect the R10 gauge connectors.

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

      Standard resistance
      Tester Connector Condition Specified Condition
      S61-7 (FR) - S11-2 Always Below 1 Ω
      S61-18 (FE) - R10-2
      S61-7 (FR) or S11-2 - Body ground Always 10 kΩ or higher
      S61-18 (FE) or R10-2 - Body ground

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  5. CHECK HARNESS AND CONNECTOR (FUEL SUCTION PLATE SUB-ASSEMBLY - FUEL SENDER GAUGE [SUB])

    A01GY0VE03

    1. Disconnect the S11 suction plate connectors.

    2. Disconnect the R10 gauge connectors.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      S11-3 - R10-1 Always Below 1 Ω
      S11-3 or R10-1 - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  6. INSPECT FUEL SENDER GAUGE ASSEMBLY (MAIN)

    A01GYVJE05

    1. Remove the fuel sender gauge (main) Click here.
