STEERING WHEEL SENSOR CALIBRATION


caution After the next operation has been completed, carry out the following two operations:

  • Alignment adjustment <Front>
  • Steering wheel sensor (column switch assembly) replacement, removal, installation

  1. Update the neutral position stored in the steering wheel sensor.
  2. Reset the calibrated value of the steering angle stored in ASC-ECU.
caution
  • Before performing the calibration, check if the steering wheel sensor-related diagnosis code is set in ASC-ECU.
  • When the diagnosis code other than C1394 is set, carry out the inspection according to each troubleshooting procedure.
1.Park the vehicle on a level surface with tyres and steering wheel positioned in a straight ahead direction.
2.Turn the electric motor switch to the "ON" position.

7.In "System table" of "System selection," select "Steering angle sensor," and then press the "OK" button.
8.In "Steering angle sensor," select "Special function."
9.In "Special function," select "Learn neutral position of steering angle sensor."
note When the neutral position of steering angle sensor has been learned, "Neutral position learned already: in order to relearn the neutral position, press the "OK" button to initialise the steering angle sensor neutral position." is displayed. If it is okay, press the "OK" button.
10.In "Learn neutral position of steering angle sensor," "Initialise neutral position of steering angle sensor" is selected, thus press the "OK" button.
note When the neutral position of steering angle sensor has been learned, "Initialise neutral position of steering angle sensor: Do you want to execute? Note: The diagnosis code will be erased." is displayed. Then, press the "OK" button.
11."Initialise neutral position of steering angle sensor: Completed" is displayed. Then, press the "OK" button.

14."Learn neutral position of steering angle sensor: Completed" is displayed. Then, press the "OK" button.
15.After turning the electric motor switch to "LOCK" position, turn it to the "ON" position again.
16.On the Menu, select "System selection."
17.On the "System selection," select "ABS/ASC/ASTC" in the "System table," and then click the "OK" button.
18. In the "ABS/ASC/ASTC" field, select "Special function".
19.In the "Special function," select "Learn sensor neutral position."
20.In "Learn sensor neutral position," select "Learn neutral position of steering angle sensor," and then press the "OK" button.
21."Learn neutral position of steering angle sensor: Are you sure to execute the selected item? Note: Check the execution conditions." is displayed. Then, press the "OK" button.
22."Execute command: Executed" is displayed. Then, press the "OK" button.
23.The neutral point is learned.
