Clearance Sonar System -- Initialization



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

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 sensor is removed and installed
When steering 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 sensor is removed and installed
When steering 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 sensor is removed and installed
When steering sensor is replaced

Method 1 (Intelligent tester)

  1. Turn the engine switch off.

  2. Connect the intelligent tester to the DLC3.

  3. Turn the engine switch on (IG) and push the intelligent tester main switch ON.

  4. Select the following menus: "Body / Clearance Sonar".



  5. Perform the Steering Initialization procedure from the Clearance Sonar / Utility menu.

Method 2 (Manual operation method)


  1. Using customize mode, set the mid-point and maximum steering angle.

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

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.

    NOTICE:
    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.


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.
