POWER STEERING: ELECTRONIC POWER STEERING SYSTEM: C1528: Motor Rotation Angle Sensor Malfunction

DTC C1528 - Motor Rotation Angle Sensor Malfunction

DESCRIPTION

The motor rotation angle sensor detects the motor rotation angle and sends this information to the power steering ECU assembly.

WIRING DIAGRAM

INSPECTION PROCEDURE

PROCEDURE

1. CHECK POWER STEERING EARTH WIRE (POWER STEERING LINK ASSEMBLY - BODY GROUND)
(a) Check the installation condition of the power steering earth wire connected to the power steering link assembly.
OK:
The power steering earth wire is securely installed to the power steering link assembly and body ground.
NG -- REINSTALL POWER STEERING EARTH WIRE
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (POWER STEERING ECU ASSEMBLY - MOTOR ROTATION ANGLE SENSOR)

(a) Disconnect the A70 connector from the power steering link assembly.
(b) Disconnect the A67 connector from the power steering ECU.
(c) Measure the resistance according to the value(s) in the table below.

Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. INSPECT POWER STEERING LINK ASSEMBLY (MOTOR ROTATION ANGLE SENSOR)

(a) Measure the resistance according to the value(s) in the table below.

Standard resistance:

NOTICE: If replacing the power steering link assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate the torque sensor zero point Calibration.

NG -- REPLACE POWER STEERING LINK ASSEMBLY
OK -- Continue to next step.
4. REPLACE POWER STEERING ECU ASSEMBLY
(a) Replace the power steering ECU assembly Removal.
NEXT -- Continue to next step.
5. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor value and calibrate the torque sensor zero point Calibration.
NEXT -- Continue to next step.
6. RECONFIRM DTC
(a) Check for DTCs Electronic Power Steering System.
