  1. CHECK VEHICLE APPROACHING SPEAKER CONTROLLER


    1. A000VUOE09

      Disconnect the L201 vehicle approaching speaker controller connector.

    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
      L201-1 (IG) - Body ground B - Body ground IG power supply Power switch on (IG) 11 to 14 V
      Power switch off Below 1 V
      L201-7 (GND) - Body ground W-B - Body ground Ground Always Below 1 Ω

      If the result is not as specified, there may be a malfunction in the wire harness.

    3. Reconnect the L201 vehicle approaching speaker controller connector.

    4. Measure the voltage and check for pulses according to the value(s) in the table below.
