ABS Solenoid Valve Rear Right Circuit. C0209 indicates that the antilock braking system (ABS) control module has detected an electrical fault in the circuit for the rear right solenoid valve, which is responsible for modulating brake pressure at that wheel during ABS operation. The module monitors voltage and current on the solenoid's control circuit and sets this code when the signal falls outside the expected range, often due to an open, short, or excessive resistance.
