        (to Pre-crash Safety City Sensor)

        Disconnect the pre-crash safety city sensor connector.

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

        Standard Voltage
        Tester Connection Switch Condition Specified Condition
        K16-7 (IG) - Body ground Ignition switch ON 11 to 14 V
        K16-7 (IG) - Body ground Ignition switch off Below 1 V

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        K16-10 (GND) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK
