    CHECK MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY


    1. for Models with Jam Protection Function on 4 Windows


      1. Disconnect the I11*1 or I22*2 switch connector.

        Tip:

        *1: for LHD

        *2: for RHD

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

        Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
        I11-12 (GND) - Body ground*1 W-B - Body ground Ground Always Below 1 Ω
        I11-11 (B) - I11-12 (GND)*1 L - W-B Battery power supply Always 11 to 14 V
