So I finally connected up the reader to see what was causing my intermittent 3 Amigos. I haven't seen much on exactly which codes require which fixes so I was hoping someone could lend a hand. When I read it with my iCarsoft I had 6 ABS codes (when viewing the systems my iCarsoft doesn't give the numbers):

Pump failure 3 (pump sticking)
PWM signal failure from engine ECU
Front Left outlet valve open circuit
Rear Right outlet valve open circuit
Pump relay open circuit
Shuttle valve switch electrical failure

Would all of these be caused by the SVS electrical failure code? When should you replace the SVS versus just doing the "Option B" fix?
