      Disconnect the D1 combination meter assembly connector.

    2. Disconnect the L2 fuel sender gauge assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D1-3 (L) - L2-1 (FS) Always Below 1 Ω
      D1-3 (L) or L2-1 (FS) - Body ground Always 10 kΩ or higher
      D1-8 (FUS-) - L2-2 (FE) Always Below 1 Ω
      D1-8 (FUS-) or L2-2 (FE) - Body ground Always 10 kΩ or higher

    4. Reconnect the fuel sender gauge assembly connector.

    5. Reconnect the combination meter assembly connector.
