INTELLIGENT PARKING ASSIST SYSTEM Vehicle does not Move to Set Parking Position

INSPECTION PROCEDURE

Note


  • When "System initializing" message is displayed on the navigation receiver assembly after the battery terminal disconnected, correct the steering angle neutral point Click here.

  • Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the intelligent parking assist system may be needed Click here.

  • If initialization is necessary while performing an inspection, perform initialization first and then proceed to the next step.

PROCEDURE


  1. CHECK TIRE SIZE


    1. Check that the tire pressure and tire size are as specified. Check that there is no excessive wear on the tires.

      Result
      Result Proceed to
      Tire size is as specified and there is no excessive wear A
      Tire size is as specified but there is excessive wear B
      Tire size is not as specified but there is no excessive wear A
      Tire size is not as specified and there is excessive wear B
      Tire size is totally different from specified size B

  2. CHECK TIRE ROTATION


    1. Check tire movement distance.

      A01J8Y8E01

      1. On a level surface, center the steering wheel and stop the vehicle.

      2. Apply chalk to a point on the tire and on the ground.

      3. Drive the vehicle straight ahead, and stop the vehicle after the tire rotates 5 times.

      4. Mark the vehicle stop position on the ground, and measure the movement distance A mm (ft.). Check that the measured distance is within the standard range.

        Standard
        9582 to 9776 mm (31.44 to 32.07 ft.)

  3. CHECK SYMPTOMS


    1. Parallel parking


      1. Move the vehicle to a level surface area with parking spaces.

      2. Using the intelligent parking assist system, perform parallel parking. Check how the vehicle deviates from the set parking position.

        Tech Tips

        Begin the check with the vehicle at a 45° angle to the parking space. Perform the check from the right and left side of the parking space.

      3. Select a case below that is most similar to the problem, and follow the instructions.
