What should you do?
This code sits in the stability and traction control system. Electronic stability control, traction control and the sensors feeding them may be offline, so the car will not correct a slide for you. It will feel completely normal right up until you need it, typically in the wet or in a sudden swerve. Get it diagnosed before driving in poor conditions.
