REAR VIEW MONITOR SYSTEM (for Inner Rear View Mirror Type) TERMINALS OF ECU


  1. CHECK INNER REAR VIEW MIRROR ASSEMBLY

    A01IO8BE03

    1. Disconnect the Q6 inner rear view mirror assembly 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
      Q6-2 (E) - Body ground W-B - Body ground Ground Always Below 1 Ω
      Q6-1 (IG) - Q6-2 (E) L - W-B Ignition switch signal Ignition switch off Below 1 V
      Ignition switch 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 Q6 inner rear view mirror assembly connector.

    4. Measure the voltage according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      Q6-14 (CB+) - Q6-13 (CGND) B - Shielded Power source Ignition switch ON, shift lever in R 5.5 to 7.05 V
      Q6-13 (CGND) - Body ground Shielded - Body ground Shielding Always Below 1 V
      Q6-3 (REV) - Q6-2 (E) R - W-B Reverse signal Ignition switch ON, shift lever in R 11 to 14 V
      Ignition switch ON, shift lever not in R Below 1 V
      Q6-7 (CV+) - Q6-6 (CV-) R - W Display signal Ignition switch ON, shift lever in R Pulse generation (see waveform 1)
      Ignition switch ON, shift lever in R, screen blacked out by covering camera lens Pulse generation (see waveform 2)

      If the result is not as specified, the inner rear view mirror assembly may have a malfunction.
