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

      Standard Resistance
      Tester Connection Condition Specified Condition
      L23-1 (TIMR) - S21-16(PTML) Power switch off Below 1 Ω
      L23-1 (TIMR) or S21-16 (PTML) - Body ground Power switch off 10 kΩ or higher

    4. Turn the power switch on (IG).

    5. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      L23-1 (TIMR) or S21-16 (PTML) - Body ground Power switch on (IG) Below 1 V

      Note

      Turning the power switch on (IG) with the plugin charge control ECU assembly connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.
