WARNING: This page is about a different car, the 2006 Chrysler Crossfire. However, it is still accessible from the selected car via links, so may be relevant.
The vehicle in the traction control TC (ASR) mode. If the drive wheel is spinning and brake pressure is required to reduce its speed. The normally open TC (ASR) valve is energized to isolate the brake fluid being pumped from the master cylinder and to isolate the driven wheel. The normally open TC (ASR) valve bypasses the pump output back to the master cylinder at a fixed pressure setting. The normally open and normally closed valves modulate (build/decay) the brake pressure as required to slow the spinning wheel.
