3. Turn the ignition switch to the ON position, then 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, then repair or replace if necessary.
Standard voltage B+
4. Measure the voltage between steering angle sensor terminal H and the ground.
^ If there is any malfunction, inspect the wiring harness between steering angle sensor terminal H and ground point, then repair or replace if necessary.
Standard voltage 0 V
5. Turn the ignition switch off.
6. Connect the WDS or equivalent to the DLC-2.
7. Select the SWA POS PID.
8. Verify the SWA POS changes when the steering wheel is turned to the left and right.
