    1. Disconnect the N11 forward recognition camera connector.
      NOTE:
      • DTCs may be output when connectors are disconnected during inspection. Therefore, be sure to clear the DTCs using the Techstream once the inspection has been completed.
      • Do not apply excessive force to the N11 forward recognition camera connector.
    2. Measure the voltage and resistance according to the value(s) in the table below.

      HINT: 

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