Questions about Progressive Controller "fault" mode

agrazela · 02-27-2008

From what I understand, the Progressive Controller has a "fault" mode that cuts power to the 12v out (to pump) if it senses a problem (open circuit, bad pump, etc.). Do I understand that correctly?

What (if anything) happens to the controller's 5v output (for e.g., MAP sensor) when the controller goes into fault mode?

If the controller does not sence a imput for the map it will hunt for a signal by activating on and off. IE it will spray for a second.

Always check for the system check when you turn on the car. The 3rd LED blinking.

I think one of us misunderstands the other.

What I want to know is, if the controller goes into fault mode due to sensing something wrong in the pump wiring (or a break in the pump circuit, or whatever), is there any change in the 5v power output (e.g., to the MAP)?

The 5v source will remain on and does not cut voltage, But the 12v out will not be working.

That's what I wanted to know, thanks.
