CALIBRATION
1. ROTATION ANGLE SENSOR INITIALIZATION AND TORQUE SENSOR ZERO POINT CALIBRATION
NOTICE:
Clear the rotation angle sensor calibration value, initialize the rotation angle sensor, and calibrate the torque sensor zero point if any of the following has occurred:
(a) Inspection before calibration
(1) Turn the ignition switch off.
(2) Connect the Techstream to the DLC3.
(3) Turn the ignition switch to ON.
(4) Turn the Techstream on.
(5) Calibrate the power steering ECU. Enter the following menus: Chassis / EMPS / Data List.
(6) Check the values by referring to the table below.
