    E2-3 (ACCR) - A52-41 (ACCR)*2
    		Always
    		Below 1 Ω
    E2-3 (ACCR) or A38-41 (ACCR) - Body ground*1
    E2-3 (ACCR) or A52-41 (ACCR) - Body ground*2
    		Always
    		10 kΩ or higher
    HINT:
    *1: for LHD
    *2: for RHD
    Standard Resistance (for 1VD-FTV w/o DPF):
    Tester Connection
    		Condition
    		Specified Condition
    E2-3 (ACCR) - A38-13 (ACCR)*1
    E2-3 (ACCR) - A52-13 (ACCR)*2
    		Always
    		Below 1 Ω
    E2-3 (ACCR) or A38-13 (ACCR) - Body ground*1
    E2-3 (ACCR) or A52-13 (ACCR) - Body ground*2
    		Always
    		10 kΩ or higher
    HINT:
    *1: for LHD
    *2: for RHD
    Standard Resistance (for 1VD-FTV w/ DPF):
    Tester Connection
    		Condition
    		Specified Condition
    E2-3 (ACCR) - A38-22 (ACCR)*1
    E2-3 (ACCR) - A52-22 (ACCR)*2
    		Always
    		Below 1 Ω
    E2-3 (ACCR) or A38-22 (ACCR) - Body ground*1
    E2-3 (ACCR) or A52-22 (ACCR) - Body ground*2
