HINT:

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

MID-POINT LEARNING OPERATION 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 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

  3. Method 3 (Manual operation method) 
    1. Turn the engine 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. Confirm that the learning operation has been completed by checking the multi-information display.
  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.
