Scanner won't connect to my ecu

[plvcrmn]

Transit connect 04 tdci 90ps , my diagnostic system won't connect to the ecu , it is working on other cars , iv also tried a different system and that won't connect also ,,,

if OBD they may not work as diesels weren't OBD till 2004 and yours may have been built in 2003 but not registered till 2004
Also pull and check all fuses as ford have a habit of changing fuse diagrams

I have tested the obd socket for 12 volt and it is there , also it did used to connect , and if it wasn't obd compliant then how are the injectors programmed

...... and if it wasn't obd compliant then how are the injectors programmed

Via Ford IDS protocol. Some readers connect OK, some don't.

But why would it have worked a few months ago and not now ?

Your scanner might be fugged...not unheard of.

Mk6 isn't ODB-II compliant either, so just plugging any old scanner into it probably won't work. F-Super and IDS will work on Mk6.

Well another pointless reply , firstly if you read , it isn't f*** because it works ok on other vehicles and its a connect not a bag of rotting crap mk6 , so if you cannot be bothered to read a full post also if you don't know sod about what I'm asking then DONT REPLY

No need to be that nasty . After all people here are trying to help with they opinion . It is realy up to you to decide if the help given is relevant to your problem .
If scaner did connect previously but not know it could be wirring loom issue(s)........but ........this is only a sugestion .

Check all the relevant pins are still in place and not damaged on diagnostic plug
Check you have 12v on both permanent feed and ignition switched feed

And calm down and stop being a dick.

So ..... you wait til several posts in to tell us it 'used to connect up, and now it doesn't'.

Was it this same particular vehicle?
Or another one?
If the same one, what have you dicked about with on it since?

Data port is direct to the ECU via a couple of fuses, trace the pins back to the ECU plug and check continuity.

2000-2006 Transit Connects are EOBD. - No OBDII device will read/program PCM. (Just like Transit mk6)

Only Connects from 2006 onwards are OBDII Compliant.

Ford IDS will work no problem. A cheaper alternative is this F-Super2 http://www.ebay.co.uk/itm/F-Interface-S ... Sw~OdVZH1B. It will work on your connect & program injectors.

It will also work on Transit mk6's

Do you have Chassis ground on pin 4, signal ground on pin 5, SAE negative on pin 10, SAE positive on pin 2, Battery positive on pin 16 and can-bus high pin 6 and can-bus low on pin 14?

That's true, of course, but I approved the post in case the information helps someone else in the future
