  7. STEERING ANGLE SETTING (after parking assist ECU is initialized)

    Tech Tips

    If the vehicle width extension lines and predicted path lines are not aligned when the steering wheel is centered, or if the predicted path line does not move before the steering wheel is fully turned to either the left or right, adjust the steering angle settings.


    1. Center the steering wheel and stop the vehicle.

    2. Start diagnostic mode Click here.

      Note

      Be sure to apply the parking brake, depress the brake pedal and move the shift lever to P before adjusting the steering angle settings. The steering angle settings need to be adjusted while the hybrid system is stopped.

      Steering angle setting


      1. Check that the steering wheel is centered (approximately +/- 5 degrees or less) and select "STEERING CENTER MEMORIZE".

      2. After the centered steering position is memorized, turn the steering wheel to the left and then to the right full lock positions and select "MAX STEERING ANGLE MEMORIZE" or "OK".

        Tech Tips

        It is also possible to start by initially turning the steering wheel to the right side.

      3. Select "MAX STEERING ANGLE MEMORIZE" or "OK" to store the steering angle adjustment value and change the screen to the MODE SETTING screen.

        Tech Tips


        • When "MAX STEERING ANGLE MEMORIZE" or "OK" is selected, a beep will sound to confirm that the steering angle adjustment values have been stored.

        • The adjustment values will not be stored unless "MAX STEERING ANGLE MEMORIZE" or "OK" is selected.

        • When "BACK" is selected, the screen changes to SIGNAL CHECK without storing the set values.

        • If the steering angle settings have not been adjusted, selecting "MAX STEERING ANGLE MEMORIZE" or "OK" will not cause the adjustment values to be stored.

        • Even if no DTCs are detected, selecting "MAX STEERING ANGLE MEMORIZE" or "OK" may not cause the adjustment value to be stored if the steering sensor is malfunctioning.

        • If selecting "MAX STEERING ANGLE MEMORIZE" or "OK" does not cause the adjustment value to be stored after adjusting the steering angle, replace the spiral with sensor cable sub-assembly Click here.

    4. Finish diagnostic mode Click here.

    5. Confirm steering angle adjustment.

      Tech Tips

      If the steering angle has been adjusted, confirm the steering angle adjustment on the parking assist monitor screen after finishing diagnosis mode.


      1. Check on the parking assist screen that the predicted path line moves until the steering wheel is fully turned to either the left or right.

        Tech Tips

        If the predicted path line stops moving before the steering wheel is fully turned to either the left or right, the steering angle adjustment values have not been stored correctly. In this case, perform "STEERING CENTER MEMORIZE" and "MAX STEERING ANGLE MEMORIZE" again.
