We recently had a problem with a fuel system on a Peugeot, my scanner proved the fuel system had a problem which then required investigations, but then Bosch came through the door the following day with a demo on one of their KTS diagnostic hand held units, forgot the model, they advised that the fuel pump/main relay was faulty.
Our techs changed it today, I have the old one which I am going to load test it to see if it breaks down. I am cureous how the KTS can diagnose the relay as the actualy fault in the circuit, which it may do but i am just wondering how it would determine it.

peugot pump
hi there as i am driven mad with these vehicles (uk auto electrician)
the engine ecu has a built it fuel pump monitering circit and there for knows when there is a circit fault or developing problem.
the ecu applies a very low current down the pump circit and if the values dont match the data base flags up a code (fuel pump relay circit)
hope that helps
