LANE DEPARTURE ALERT SYSTEM(w/ Steering Control) TERMINALS OF ECU


  1. FORWARD RECOGNITION CAMERA

    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 Q17 forward recognition camera connector.


    1. Check forward recognition camera
