5.CHECK HARNESS AND CONNECTOR (HV CONTROL ECU - AIR BAG SENSOR ASSEMBLY CENTER)

  1. Turn the ignition switch off.

  1. Connect the H29 connector to the HV control ECU.



    A108070E02

  1. Disconnect the A24 connector from the airbag sensor assembly CTR.

  1. Measure the voltage according to the value(s) in the table below when the ignition switch is in the ON position.

    Standard voltage:
    Tester Connection
    		Specified Condition
    ABFS (H29-8) - Body ground
    		Below 1 V

  1. Turn the ignition switch off.

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

    Standard Resistance (Check for open):
    Tester Connection
    		Specified Condition
    ABFS (H29-8) - GSW2 (A24-25)
    		Below 1 Ω

    Standard Resistance (Check for short):
    Tester Connection
    		Specified Condition
    ABFS (H29-8) or GSW2 (A24-23)
    		10 kΩ or higher
