C0200 ABS Solenoid Valve Front Left Circuit

Neither the reachable J2012 tables nor NHTSA's bulletin index nor the manufacturer indexes checked contain C0200, so no published vehicle is known to use it. Its title, a circuit fault of the front left ABS solenoid valves, matches what Saab records as C2450 on 9-5 cars equipped with Bosch 5.3 TC/ABS. Each wheel channel of such a unit has an inlet valve that is open at rest and an outlet valve that is closed at rest, so the controller can hold, lower or rebuild pressure at this wheel alone; in Saab's ESP version both valves also act during stability braking. A shorted or open coil shows up in the brief valve test after key-on, which MOTOR captured as one short current pulse per coil, after which ABS and the functions built on it stay off and the lamps light.

Likely causes

Open or shorted coil of a front left valve
Poor contact between valve coils and control module (solder joint, contact strip)
Faulty valve driver in the control module

Symptoms

  • ABS warning lamp on from key-on, ABS inactive
  • Traction and stability control also switched off
