    Note:

    • DTCs may be output when connectors are disconnected during inspection. Therefore, be sure to clear the DTCs using the GTS once the inspection has been completed.

    • Do not apply excessive force to the N5 and N8 object recognition camera connector.

    CHECK OBJECT RECOGNITION CAMERA


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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      N5-7 (IGB) - Body ground R - Body ground Power source Power switch on (IG) 11 to 14 V
      Power switch off Below 1 V
      N8-1 (IG1) - Body ground B - Body ground Power source Power switch on (IG) 11 to 14 V
      Power switch off Below 1 V
      N5-1 (HTR) - Body ground BR - Body ground Object recognition camera internal heater operation signal With power switch on (IG) and object recognition camera internal heater not operating 11 to 14 V
      With power switch on (IG) and object recognition camera internal heater operating Below 1 V
      N5-10 (GND) - Body ground BR - Body ground Ground Always Below 1 Ω

    2. Measure the waveform according to the value(s) in the table below.
