Inspection Procedure

CLEAR DTC
INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT

RECONFIRM DTC

Check for DTCs.

Result

RESULT CHART

A	DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration 3 times.
B	DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration once or twice.
C	Normal system code is output.

HINT:

Replace the power steering ECU assembly if DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration 3 times.

B: Go to step 2

C: END

A: Go to next step

REPLACE POWER STEERING ECU ASSEMBLY
CLEAR DTC
INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
1. Initialize the rotation angle sensor and calibrate the torque sensor zero point (see page CALIBRATION ).

RECONFIRM DTC

Check for DTCs.

A	DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration 3 times.
B	DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration once or twice.
C	Normal system code is output.

HINT:

Replace the power steering link assembly if DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration 3 times.

NOTE:

If replacing the power steering link assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor, and calibrate the torque sensor zero point (see page CALIBRATION ).
If replacing the power steering link assembly, perform VGRS actuator angle initialization and VGRS actuator angle neutral calibration after wheel alignment adjustment (see INITIALIZATION , CALIBRATION ).

B: Go to step 6

C: END

A: REPLACE POWER STEERING LINK ASSEMBLY
