Forscan

Hello,

Is there anything online that I can refer to to find the correct values for a diagnostics scan for a Transit Custom 2.0.

Such as fuel rail pressure, NOX, DPF pressures etc etc x 1000.

First time using it. And first time scanning this van.

It will describe the fault code and you can ask Mr G (nearly always referring to posts on here)

I'm talking about live data

Try watching some of Jimmy O'Rileys videos on Youtube.

Forscan will describe the value .. what it should be and what it is .. you'll be bringing the boxes up .. standard setting has a load of boxes that may not be needed, you can swap and change them. they are called PIDS

First you have to populate forscan with the items you want to observe - then put it into "live data" mode - plenty of youtube videos on how to do that.

Then you are looking at the some values in percent ... "commanded" is what the system is asking it to do
"Actual"is what it's doing.

The DPF will be in percent soot loading

The EGR- one of the things likely to cause trouble - fault finding -You are looking for the EGR being open when it should not be open.
Anything more than brisk acceleration and EGR should be closed.
EGR only closes on acceleration .. it opens at cruise and fixed rpm.

Nox - it will say something like nox below threshold if at fault, think nox is all to do with, if the adblue system is doing its stuff.

all the best.mark
