Inspection Procedure

NOTE: If the steering column or power steering ECU has been replaced, perform the rotation angle sensor initialization and torque sensor zero point calibration (See CALIBRATION ).

CHECK CONNECTOR CONNECTION CONDITION
1. Check the installation condition of the motor rotation angle sensor connector.
  OK:
  
  Motor rotation angle sensor connector is securely connected to the power steering ECU.
NG : CONNECT CONNECTOR

OK: Go to next step

READ VALUE USING TECHSTREAM (MOTOR ROTATION ANGLE SENSOR)

Turn the ignition switch to OFF.
Connect the Techstream to the DLC3.
Turn the ignition switch to ON.
Turn the Techstream on.
Enter the following menus: Chassis / EMPS / Data List /

Select the item "Motor Rotation Angle" in the Data List and read the value displayed on the Techstream.
