    (to Fuel Sender Gauge Assembly)

    1. Disconnect the F10 fuel sender gauge connector.

    2. Check the meter indicator condition.

      Standard
      Europe
      Wire connection Condition Specified Condition
      F10-2 - F10-3 Short circuit (Ignition switch ON) Fuel gauge indicates "F" or more (Combination meter)
      Singapore
      Wire connection Condition Specified Condition
      F10-1 - F10-2 Short circuit (Ignition switch ON) Fuel gauge indicates "F" or more (Combination meter)

    3. Measure the voltage.

      Standard voltage
      Europe
      Tester Connection Condition Specified Condition
      3 - Body ground Ignition switch ON 4 to 7 V
      Singapore
      Tester Connection Condition Specified Condition
      2 - Body ground Ignition switch ON 4 to 7 V

    4. Reconnect the connector.

  2. INSPECT FUEL SENDER GAUGE

    A01KER7E01

    1. Remove the fuel sender gauge assembly.

    2. Check that the float position is between E and F and measure resistance between terminals 2 and 3*1 or 1 and 2*2 of connector.

      *1: Europe

      *2: Singapore

    3. Measure the resistance.

      Standard resistance
      Float level Float position mm (in.) Specified Condition
      F 75.7 (2.98) +/- 4 (0.16) 3.0 +/- 0.6 Ω
      1/2 173.3 (6.82) 29.5 +/- 1.5 Ω
      E 288.7 (11.37) +/- 4 (0.16) 110.0 +/- 2.5 Ω

    4. Reinstall the fuel sender gauge assembly.

    1. Disconnect the C13 combination meter assembly connector.

    2. Disconnect the F10 fuel sender gauge connector.

    3. Measure the resistance.

      Standard resistance
      Europe
      Tester connection Specified condition
      C13-26 - F10-3 Below 1 Ω
      C13-31 - F10-2 Below 1 Ω
      F10-2 - Body ground Below 1 Ω
      C13-26 or F10-3 - Body ground 10 kΩ or higher
      Singapore
      Tester connection Specified condition
      C13-26 - F10-2 Below 1 Ω
      C13-31 - F10-1 Below 1 Ω
      F10-1 - Body ground Below 1 Ω
      C13-26 or F10-2 - Body ground 10 kΩ or higher

    4. Reconnect the connectors.
