AUDIO AND VISUAL SYSTEM (w/o Stereo Component Amplifier) TERMINALS OF ECU


  1. CHECK RADIO RECEIVER

    A0155SBE04

    1. Disconnect the F35 receiver connector.

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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specification
      F35-4 (B) - F35-7 (GND) L - BR Battery Always 11 to 14 V
      F35-7 (GND) - Body ground BR - Body ground Ground Always Below 1 Ω
      F35-3 (ACC) - F35-7 (GND) GR - BR Accessory (ON) Ignition switch off Below 1 V
      Ignition switch ACC 11 to 14 V
      F35-10 (ILL+) - F35-7 (GND) G - BR Illumination signal Ignition switch ON, light control switch off Below 1 V
      Ignition switch ON, light control switch tail or on 11 to 14 V

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

    3. Reconnect the F35 receiver connector.
