No reachable J2012 list carries C0288, and no known maker files a yaw rate range fault under it. GM's PIP5094 contains the number, and AA1Car's GM brake table gives it a quite different meaning: Brake Warning Lamp Circuit Shorted to B+. The title describes a yaw rate signal that leaves its permitted span. Where GM documents that case, it uses C019B instead: on the 2011 Saab 9-5 the brake module flags a yaw signal out of its specified range and then turns ESP and the hill start aid off until the next ignition cycle. The older Saab 9-5 sensor covers about ±138 degrees per second, reads zero at rest and is checked every 20 ms. Bosch explains the micromechanical Coriolis measurement used in such sensors.

Likely causes

Sensor bracket loose, bent or sensor mounted crooked after body repair
Yaw rate sensor drifting internally
Unstable supply or ground at the sensor

Symptoms

  • Stability and traction control warning lamp on
  • Stability control disabled for the rest of the trip
