Day

17964 charge pressure control negative deviation

18009 power supply (terminal 30 b+) relay j317 unplauaible signal

That is how its read on the omnitec scanner at work

I have this same problem!!

Change the Vac box on the left wing first to see if that fixes it. Heard of a few of these going bad. I have got a working one you can have cheap if you need it. Also check the wiring to the vac box. : http://wiki.ross-tec...64/P1556/005462
