Steering Angle Sensor: Testing and Inspection

STEERING ANGLE SENSOR INSPECTION

1. Remove the column cover.

2. Turn the ignition switch to the ON position and measure the voltage between steering angle sensor terminal A and ground.






- If there is any malfunction, inspect the wiring harness between steering angle sensor terminal A and ignition switch. Repair or replace if necessary. (without DSC)
- If there is any malfunction, inspect the wiring harness between steering angle sensor terminal A and DSC HU/CM terminal AB. Repair or replace if necessary. (with DSC)

Standard voltage
- B+

3. Measure the voltage between steering angle sensor terminal D and ground.

- If there is any malfunction, inspect the wiring harness between steering angle sensor terminal D and EHPAS control module terminal 3A. Repair or replace if necessary. (without DSC)
- If there is any malfunction, inspect the wiring harness between steering angle sensor terminal D and DSC HU/CM terminal AH. Repair or replace if necessary. (with DSC)

Standard voltage
- 0 V

4. Turn the ignition switch off.

5. Connect the M-MDS to the DLC-2.






6. Select the STEER_RATE PID. (see Testing and Inspection.)

7. Verify the STEER_RATE changes when the steering wheel is turned to the left and right.

- If there is any malfunction, replace the steering angle sensor. Service and Repair

Standard
- When the steering wheel is turned to the left:
STEER_RATE changes positively.
- When the steering wheel is turned to the right:
STEER_RATE changes negatively.
