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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    H59-2 (GND) - Body ground
    		Always
    		Below 1 Ω
    H59-6 (GND2) - Body ground
    		Always
    		Below 1 Ω
    H55-10 (LRHD) - Body ground*1
    		Always
    		Below 1 Ω

    1. *1: for RHD

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