Intuitive Parking Assist System: Initialization

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 METHODS REFERENCE CHART

Method 1	Use intelligent tester 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

Method 1 (Intelligent tester)
1. Turn the power switch OFF.
2. Connect the intelligent tester to the DLC3.
3. Turn the power switch ON (IG) and push the intelligent tester main switch ON.
4. Select the following menus: "DIAGNOSIS / OBD".
5. Perform the STEERING INIT procedure from the INTUITIVE P/A menu.

  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.

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.
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.
