• When exchanging the rack position sensor, be sure to do following procedure before removing the rack
position sensor (Refer to "Diagnosis Manual V1505-T-E4 (9Y120-02490)" for the detail).
1. Do Utility "Gear Case or Gear Case Gasket or Rack Position Sensor Exchange" by using diagmaster
and get "Actual Rack Position Before Exchange".
2. Exchange the rack position sensor.
3. Get "Actual Rack Position After Exchange".
4. Rack Position Offset Correction is calculated automatically.
5. Register the offset data to ECU.
• Since it is not possible to do unit checking for this sensor, judge the sensor is faulty if the relating electric
circuit is normal.
