Electronic Power Steering System
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:
^
The power steering ECU assembly has been replaced.
^
The power steering link assembly has been replaced.
^
Steering effort differs between left and right.
(a)
Inspection before calibration
(1) Connect the intelligent tester to the DLC3.
(2) Turn the engine switch on (IG).
(3) Turn the intelligent tester on.
(4) Select "IG SUPPLY" from the data list.
(5) Check the IG power supply voltage on the tester screen.
Voltage: 10 to 14 V
NOTICE:
If the IG power supply voltage is 9 V or less, calibration cannot be performed. In this case, charge or replace the battery, and then
perform calibration.
(b) Rotation angle sensor calibration value clear, rotation angle sensor initialization, and torque sensor zero point calibration
NOTICE:
^
If DTC C1516 (Torque Sensor Zero Point Adjustment Incomplete) is stored, the torque sensor zero point cannot be calibrated. Clear the
DTC before starting calibration.
^
If DTC C1526 (Rotation Angle Sensor Initialization Incomplete) is stored, the rotation angle sensor cannot be initialized. Clear the DTC
before starting initialization.
(1) Connect the intelligent tester to the DLC3.
(2) Turn the engine switch on (IG).
(3) Turn the intelligent tester on.
(4) Select "TRQ SENSOR ADJ".
(5) Follow the procedures on the tester display to clear the rotation angle sensor calibration value, initialize the rotation angle sensor, and
calibrate the torque sensor zero point.
NOTICE:
^
When initializing the rotation angle sensor, observe the following to stabilize sensor voltage:
^
After turning the engine switch on (IG), wait for at least 2.5 seconds before turning the steering wheel. Do not turn the steering
wheel quickly.
^
The steering wheel will vibrate during torque sensor zero point calibration. Do not touch the steering wheel while it is vibrating or
for 2 seconds after it stops.

NOTICE:
Use this procedure to center the steering wheel if:
^
The steering actuator has been replaced,
^
The steering control ECU has been replaced,
^
The steering column or gear has been disconnected, or
