PROCEDURE


  1. CHECK FOR DTCs (PRE-COLLISION SYSTEM, DRIVING SUPPORT COMPUTER)


    1. Clear the DTCs.

      Click here


      Body Electrical > Pre-Collision System > Clear DTCs
      Body Electrical > Driving Support Computer > Clear DTCs

    2. Make sure that the DTC detection conditions are met.

      Tech Tips

      If the detection conditions are not met, the system cannot detect the malfunction.

    3. Check the DTCs.
