- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0206 is not documented publicly; the publicly available J2012 lists, the NHTSA bulletin index and maker indexes do not contain it. The title describes an electrical fault of the left rear ABS valves, which Saab's 9-5 TC/ABS data file as C2415 and watch for opens and shorts at all times, with the active valve check above 6 km/h. On the rear axle these valves matter even without wheel lock: Saab's 9-3 ESP description explains that electronic brake-force distribution operates each wheel's inlet and outlet valve, without the pump, to keep rear pressure from locking the rear wheels first. A failed rear valve therefore costs EBD as well as ABS, which is why the brake lamp lights next to the ABS lamp. MOTOR's current-probe recordings show such a coil fault as a missing test pulse.
