Intuitive Parking Assist System: Initialization

  1. PERFORM INITIAL SETTING OF STEERING ANGLE MID-POINT AND MAXIMUM STEERING ANGLE 

    HINT:

    The mid-point learning operation (steering angle midpoint, maximum steering angle) can be performed using 4 methods:

    MID-POINT LEARNING OPERATION CHART

    Method 1 Use the Techstream to perform initial setting of mid-point When clearance warning ECU is replaced
    When steering wheel mid-point or wheel alignment is adjusted
    When cable of battery terminal is disconnected and reconnected
    When malfunction causes momentary drop in the power supply voltage (due to cranking, depleted battery, etc.)
    When steering angle sensor is removed and installed
    When steering angle sensor is replaced
    Method 2 Use customize mode to perform initial setting of mid-point When clearance warning ECU is replaced
    When steering wheel mid-point or wheel alignment is adjusted
    Method 3 Perform steering angle mid-point learning operation by rotating steering wheel to left and right full lock position When battery terminal is disconnected and reconnected
    When malfunction causes momentary drop in the power supply voltage (due to cranking, depleted battery, etc.)
    When steering angle sensor is removed and installed
    When steering angle sensor is replaced
    Method 4 Perform steering angle mid-point learning operation by traveling in approximate straight line for extended distance When battery terminal is disconnected and reconnected
    When malfunction causes momentary drop in the power supply voltage (due to cranking, depleted battery, etc.)
    When steering angle sensor is removed and installed
    When steering angle sensor is replaced
    1. Method 1 (Techstream)
      1. Turn the power switch off.
      2. Connect the Techstream to the DLC3.
      3. Turn the power switch ON (IG).
      4. Turn the Techstream on.
      5. Enter the following menus: Body Electrical / INTUITIVE P/A/Utility.
      6. Perform the STEERING INITIALIZATION procedure.
    2. Method 2 (Manual operation method)
      1. Using customize mode, set the mid-point and maximum steering angle.

        HINT:

        • *1: Steering wheel is centered (tires aligned straightforward).
        • *2: If 180 seconds pass, steering angle midpoint setting and maximum steering angle range setting will not occur and initialize mode will end.

    3. Method 3 (Manual operation method)
      1. Turn the power switch on (IG).
      2. Turn the clearance sonar main switch ON.
      3. Turn the steering wheel to the full left and right lock position.
        NOTE: Make sure to completely turn the steering wheel to the left and right full lock position.
    4. Method 4 (Manual operation method)
      1. At an area with few turns and curves, and minimal traffic, drive at 20 km/h (12 mph) or more for 5 minutes or more.
