Troubleshooting & Fixing Hyundai Elantra with Persistent EPS & Traction Control Dashboard Lights

Troubleshooting and fixing a Hyundai Elantra Touring 2012 with EPS and traction control lights that won't go away after starting the car.

DTC Codes detected:

C1260 Steering angle sensor circuit-Signal
C1259 Steering angle sensor-Electrical
C1261 Steering angle sensor not calibrated

Ran an ASP (absolute steering position) calibration to fix this issue. The Elantra does not seem to have any other SAS (Steering Angle Sensor) calibration. The service manual mentions you can also do a "EPS type recognition", but I found my car was already properly set to "North America".
