Pacifica V6-3.8L VIN L (2005)
The hydraulic diagram shows the vehicle in the traction control (TC) mode (Fig. 9). The diagram shows a 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 the spinning wheel.
