Hello
I'm having a bit of trouble getting my new diagnostic tool to work and I was hoping one of you can help. My Car is a 406 HDi 110 Year 2000. Can anyone who owns a similar Motor just measure the pin voltages of the EOBD2 connector in particular the Pin 7 K line. If you look at the connector on the wider edge count along 7 pins and put your red probe on the pin and the black probe on a good earth - ignition on. If a few owners compare this figure it would be really usefull since it is a source of a problem on some.
Cheers

Re: Diagnostic Plug
Pre-2001 406s have 'issues' speaking to generic diag tools and fault code readers
<steve_earwig> I think this forum is more about keeping our cars going with minimal outlay than giving our cars more reason to go bang

Hello
Thank you for your reply. That's what I've been told, however, I can read all the generic engine data on this with a PCMSCAN but the Lexia 3 Planet pp2000 Peugeot cannot. On other makes of cars the pin 7 K line usually reads 3.5volts but on this Peugeot it only reads .045volt which I would normally assume to be a fault in a controller connected to that line, however, the wiring diagram shows it going straight to the ECU where the same voltage is read. This would appear to rule out a controller pulling the voltage down through a short etc. If others get the same voltage as this one I can assume it's normal for this system. So it would helpful if others can compare.
Thank again in anticipation.

Re: Diagnostic Plug
I'm guessing that pin is an open collector output, there is probably a pull up resistor in the Lexia interface.
406 estate, 2.1TD, I fixed her, then part exchanged her for a Mercedes E300TD Avantgarde Estate.
Hmmmm, straight 6 goodness!

The standard EOBD connector should be a universal standard as far as it's pin out purpose as a signal carrier, however, I don't believe the value has to be the same hence the inability of different scanners for variuos makes to read each others data unless it's a universal scanner costing meggar £s. But for this purpose the PP2000 planet is designed to read all peugeot models from 1996 onwards so should, if there are no system faults, read the data. This is what I'm attempting to resolve whether there is an inherant fault. The confusing part is that the simple generic Elm tool reads everything that matters on live engine data. It cannot of course read and interrogate BSI and other OEM data streams which is what I need the Lexia for - setting up spare keys and stuff for friends and family who have a wide variety of Peugeot models.
I would really appreciate any help I can get.
Thank you so much.
