Toyota Venza: Torque Sensor Zero Point Adjustment Undone (C1515,C1525)
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 have not been performed.
|
DTC No. |
DTC Detection Condition |
Trouble Area |
|---|---|---|
|
C1515 |
This DTC is detected when torque sensor zero point calibration has not been performed. |
There is no malfunction if this DTC is not output again after performing torque sensor zero point calibration. |
|
C1525 |
This DTC is detected when rotation angle sensor value initialization has not been performed. |
There is no malfunction if this DTC is not output again after 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 .gif)
).
PROCEDURE
|
1. |
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 ).

|
2. |
CHECK FOR DTC |
(a) Check for DTCs (See page ).
|
Condition |
Proceed to |
|---|---|
|
DTC C1515 or C1525 is still output after performing rotation angle sensor value initialization and torque sensor zero point calibration 3 times. |
A |
|
DTC C1515 or C1525 is not output. |
B |
NOTICE:
If DTC C1515 or C1525 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 C1515 or C1525 is still output after performing rotation angle sensor value initialization and torque sensor zero point calibration 3 times.

Torque Sensor Circuit Malfunction (C1511-C1514,C1517)
DESCRIPTION
The torque sensor converts the rotation torque input to the steering wheel into
an electrical signal and sends it to the power steering ECU. Based on this signal,
the ECU detects stee ...
PS Warning Light Remains ON
DESCRIPTION
If the power steering ECU detects a malfunction, the P/S warning light comes
on. At this time, the power steering ECU stores a DTC in its memory.
