Toyota Venza: Torque Sensor Zero Point Adjustment Incomplete (C1516,C1526)

Toyota Venza Service Manual / Power Assist Systems / Power Steering System / Torque Sensor Zero Point Adjustment Incomplete (C1516,C1526)

DESCRIPTION

These DTCs do not indicate a malfunction. The power steering ECU stores these DTCs when it determines that the rotation angle sensor value initialization and torque sensor zero point calibration are incomplete.

DTC No.

DTC Detection Condition

Trouble Area

C1516

Torque sensor zero point calibration is incomplete due to the steering wheel being touched during calibration.

There is no malfunction if this DTC is not output again after clearing the DTCs and torque sensor calibration value, and performing zero point calibration.

C1526

Rotation angle sensor value initialization is incomplete due to the steering wheel being touched during calibration.

There is no malfunction if this DTC is not output again after clearing the DTCs and torque sensor calibration value, and performing rotation angle sensor value initialization.

CAUTION / NOTICE / HINT

NOTICE:

If the power steering ECU and steering column assembly have been replaced, perform the rotation angle sensor initialization and torque sensor zero point calibration (See page ).


PROCEDURE

1.

CLEAR DTC

(a) Clear the DTCs (See page ).



NEXT

2.

INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT

(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point (See page ).



NEXT

3.

CHECK FOR DTC

(a) Check for DTCs (See page ).


Condition

Proceed to

DTC C1516 or C1526 is still output after performing rotation angle sensor value initialization and torque sensor zero point calibration 3 times.

A

DTC C1516 or C1526 is not output.

B

NOTICE:

If DTC C1516 or C1526 is output even though the rotation angle sensor value initialization and torque sensor zero point calibration have been performed, confirm the procedure again, and perform the calibration and initialization 3 times.

HINT:

Replace the power steering ECU if DTC C1516 or C1526 is still output after performing rotation angle sensor value initialization and torque sensor zero point calibration 3 times.


B

END


A

4.

REPLACE POWER STEERING ECU

(a) Replace the power steering ECU (See page ).



NEXT

5.

CLEAR DTC

(a) Clear the DTCs (See page ).



NEXT

6.

INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT

(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point (See page ).



NEXT

7.

CHECK FOR DTC

(a) Check for DTCs (See page ).


Condition

Proceed to

DTC C1516 or C1526 is still output after performing rotation angle sensor value initialization and torque sensor zero point calibration 3 times.

A

DTC C1516 or C1526 is not output.

B

NOTICE:

If DTC C1516 or C1526 is output even though the rotation angle sensor value initialization and torque sensor zero point calibration have been performed, confirm the procedure again, and perform the calibration and initialization 3 times.

HINT:

Replace the power steering gear if DTC C1516 or C1526 is still output after performing rotation angle sensor value initialization and torque sensor zero point calibration 3 times.


A

REPLACE STEERING COLUMN ASSEMBLY
