  2. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (FUEL RECEIVER GAUGE)


    1. Operate the intelligent tester according to the steps on the display and select "Active Test".

      Combination Meter:
      Tester Display Test Part Control Range
      Fuel Meter Operation Fuel receiver gauge EMPTY, 1/2 or FULL
      OK
      Needle indication is normal.

    NG

    REPLACE NO. 1 METER ECU

    OK

  3. READ VALUE USING INTELLIGENT TESTER (FUEL SENDER GAUGE)


    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.

    OK

    REPLACE NO. 1 METER ECU

    NG

  4. INSPECT FUEL SENDER GAUGE ASSEMBLY (MAIN)

    A001BRWE01
    *1 Component without harness connected: (Fuel Sender Gauge (Main))
    *2 F (Upper)
    *3 E (Lower)

    1. Remove the fuel sender gauge (main).

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

      Standard resistance
      Tester Connection Condition Specified Condition
      1 (FE) - 2 (S) Float level is F (upper) 6.5 to 8.5 Ω
      Between float level is F (upper) and E (lower) 91.0 to 102.2 Ω
      Float level is E (lower) 184.8 to 188.8 Ω

    NG

    REPLACE FUEL SENDER GAUGE ASSEMBLY (MAIN) Click here

    OK

  5. INSPECT FUEL SENDER GAUGE ASSEMBLY (SUB)

    A001FXXE01
    *1 Component without harness connected: (Fuel Sender Gauge (Sub))
    *2 F (Upper)
    *3 E (Lower)

    1. Remove the fuel sender gauge (sub).

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

      Standard resistance
      Tester Connection Condition Specified Condition
      1 (S) - 2 (E) Float level is F (upper) 6.5 to 8.5 Ω
      Between float level is F (upper) and E (lower) 112.7 to 125.7 Ω
      Float level is E (lower) 220.7 to 225.7 Ω

    NG

    REPLACE FUEL SENDER GAUGE ASSEMBLY (SUB) Click here

    OK

  6. CHECK HARNESS AND CONNECTOR (REAR JUNCTION BLOCK - FUEL SENDER GAUGE)

    A001BGRE02
    *1 Front view of wire harness connector: (to Rear Junction Block ECU)
    *2 Front view of wire harness connector: (to Fuel Sender Gauge (Sub))
    *3 Front view of wire harness connector: (to Fuel Sender Gauge (Main))

    1. Disconnect the S61 junction block connector.

    2. Disconnect the S11 and R10 gauge connectors.

    3. 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

  7. CHECK HARNESS AND CONNECTOR (FUEL SENDER GAUGE (MAIN) - FUEL SENDER GAUGE (SUB))

    A001CE1E02
    *1 Front view of wire harness connector: (to Fuel Sender Gauge (Main))
    *2 Front view of wire harness connector: (to Fuel Sender Gauge (Sub))

    1. Disconnect the S11 and R10 gauge connectors.

    2. 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

  8. REPLACE NO. 1 METER ECU


    1. Temporarily replace the No. 1 meter ECU with a new one.


    NEXT

  9. CHECK NO. 1 METER ECU (FUEL RECEIVER GAUGE)


    1. Check that the operation of the fuel sender gauge in the meter returns to normal Click here.

      OK
      Operation of the fuel sender gauge returns to normal.

    OK

    END (NO. 1 METER ECU IS DEFECTIVE)

    NG

    REPLACE LUGGAGE ROOM JUNCTION BLOCK ASSEMBLY (REAR JUNCTION BLOCK ECU)
