•  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)

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)

4.  Turn the ignition switch off.

5.  Connect the M-MDS to the DLC-2.

6.  Select the STEER_RATE PID. (see ON-BOARD DIAGNOSIS[ELECTRO HYDRAULIC POWER ASSIST STEERING (EHPAS)].)

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. (See CLOCK SPRING REMOVAL/INSTALLATION.)
