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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      F56-14 (ABFS) - Body ground Ignition switch ON (IG) Below 1 V

      Note

      Turning the ignition switch to ON (IG) with the airbag sensor assembly connector and the hybrid vehicle control ECU connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

    5. Turn the ignition switch off.

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

      Standard Resistance (Check for Open)
      Tester Connection Switch Condition Specified Condition
      F56-14 (ABFS) - F14-14 (GSW2) Ignition switch off Below 1 Ω
      Standard Resistance (Check for Short)
      Tester Connection Switch Condition Specified Condition
      F56-14 (ABFS) or F14-14 (GSW2) - Body ground and other terminals Ignition switch off 10 kΩ or higher

    7. Connect the airbag sensor assembly connector.

    8. Connect the hybrid vehicle control ECU connector.
