4.CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH - BODY GROUND)


    A112793E02

  1. Disconnect the S35 park/neutral position switch connector.

  1. Turn the ignition switch to the ON position.

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

    Standard Voltage:
    Tester Connection
    		Specified Condition
    +B (S35-8) - Body ground
    		10 to 14V

    NOTICE:
    Turning the ignition switch to the ON position with the park/neutral position switch connector disconnected causes other DTCs to be stored. Clear the DTCs after performing the inspection.
