C1513
POWER STEERING: POWER STEERING SYSTEM: C1511-C1513: Torque Sensor Circuit Malfunction
DESCRIPTION
The torque sensor converts rotation torque input to the steering wheel into an electrical signal and sends it to the ECU. Based on this signal, the ECU detects steering effort.
WIRING DIAGRAM
INSPECTION PROCEDURE
PROCEDURE
1. CHECK WIRE HARNESS (POWER STEERING ECU - TORQUE SENSOR)
(a) Disconnect the C4 connector from the power steering ECU.
(b) Disconnect the C1 connector from the torque sensor.
(c) Measure the resistance of the wire harness connector.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
2. INSPECT POWER STEERING LINK ASSEMBLY (TORQUE SENSOR)
(a) Measure the resistance of the torque sensor connector.
Standard resistance:
NOTICE:
- 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 Power Steering System.
- If replacing the power steering link assembly, perform VGRS actuator angle initialization Initialization and VGRS actuator angle neutral calibration Calibration after wheel alignment adjustment.
NG -- REPLACE POWER STEERING LINK ASSEMBLY
OK -- Continue to next step.
3. REPLACE POWER STEERING ECU ASSEMBLY
(a) Replace the power steering ECU Removal.
NEXT -- Continue to next step.
4. INITIALIZE ROTATION ANGLE SENSOR AND CALIBRATE TORQUE SENSOR ZERO POINT
(a) Initialize the rotation angle sensor and calibrate the torque sensor zero point Power Steering System.
NEXT -- Continue to next step.
5. RECONFIRM DTC
(a) Check for DTCs Power Steering System.
(b) Is DTC C1511, C1512 or C1513 output?
OK:
DTC is not output.
NOTICE:
- 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 Power Steering System.
- If replacing the power steering link assembly, perform VGRS actuator angle initialization Initialization and VGRS actuator angle neutral calibration Calibration after wheel alignment adjustment.
NG -- REPLACE POWER STEERING LINK ASSEMBLY
OK -- END
