1. 4. Is the measured waveform within specifications?

   YES 

   • Fault is intermittent caused by poor connection in steering sensor harness and/or HECU's connector.

     Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

   NO 

   • If STN signal is HIGH on center position, Check for improper installation of steering angle sensor. Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

     If sensor mounting state is normal, Substitute with a known-good steering angle sensor and check for proper operation.

     If problem is corrected, replace steering angle sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
