C0710 does not appear in the publicly available J2012 lists, yet GM uses it widely in the brake control module for the steering angle it feeds to stability control. Saab 9-5 2011 wording matches the title for subcode 00 and adds 42 (centering not stored) and 5A (signal missing, offset out of range or at odds with yaw rate); the 9-4X adds 71 for invalid data. The sensor should sweep from -550 to +550 degrees. When the code sets, StabiliTrak is switched off for that ignition cycle. GM bulletins give typical causes: a wheel mounted one spline off (PIT4225F, 2007-13 trucks), lift kits, other wheelbases or tyre sizes (PIT4322G), a worn lower column bearing on the 2005-06 STS (PIC3171E), and the wrong sensor calibration after programming 2010 hybrid trucks (PIT5207).

Likely causes

Steering angle sensor not centred after alignment or repair
Steering wheel mis-splined, or suspension, wheelbase or tyres changed
Faulty steering angle sensor, connector or worn column bearing
Brake module programmed for the wrong sensor design

Symptoms

  • Service StabiliTrak or stability message, ESC indicator on
  • Unwanted stability intervention while cornering
