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.

Likely causes

Open or shorted coil of a rear left valve
Cracked solder joint or contact strip, often worse when cold
Faulty valve driver in the control module

Symptoms

  • ABS and red brake warning lamps on
  • No ABS or electronic brake-force distribution, rear may lock early

Repair estimate
