Inspection Procedure

  1. CHECK CAN BUS LINE (MAIN BUS LINE FOR DISCONNECTION, BUS LINES FOR SHORT CIRCUIT) 
    1. Measure the resistance according to the value(s) in the table below.

    Standard: 

    TERMINALS RESISTANCE SPECIFIED VALUE

    Tester connection Condition Specified value Result
    D1-6 (CANH) - D1-14 (CANL) IG switch OFF 54 to 69 Ω OK
    D1-6 (CANH) - D1-14 (CANL) IG switch OFF 69 Ω or higher NG-A
    D1-6 (CANH) - D1-14 (CANL) IG switch OFF Below 54 Ω NG-B
