Title: ABS diagnostic socket location
Post by: petergalileo on July 30, 2006, 18:07:47

Just tried to follow the abs diagnostics proceedure on my N reg 300TDI (has EGR) and cant find the blue diagnostic connector.  I notice theres an OBD connector in the drivers footwell I am wondering if the abs diagnostic socket has been integrated into that, if so, can I short the pink/black and black wire on that to get the codes to flash ?

Thanks

Its somewhere up round the steering column. To the right of the column a 5 way blue connector.

Nope, been looking for 10 minutes, absolutely nothing even remotely resembling it in the location specified.

Eureka !

I was right, after 1996 the ABS connector was integrated into the Main ECU fault code reader socket in the footwell top panel.

Have read the code and I have too large an air gap on my front right side sensor, strange as I removed it and reseated it earlyer, will have another look and replace it if it happens again.

Thanks

Make sure all your wheel bearings are OK before trying to sort the ABS light / sensors :wink:

Which wires did you need to bridge on the OBD2?
Were they just the same colour as described in the guide?
As i too am unable to find the blue ABS plug.


Cheers,

Its been ages since I did this, I have a diagnostic available now :)

I beleve its the same colour wire as in the article you read but it goes to the obd plug instead of running to its own diagnostic connector.

The other colour is either of the black ones as they are both earths.

Such a shame you are so far away otherwise i would be paying you a visit.
For such an important socket, there doesn't seem to be many wires going to the OBD, 8-10 maybe, would have expected more.
Also my Disco was registered on the 13/09/95 (N reg) but i'm sure it doesn't have the seperate abs plug.

Couldn't get the blink test to work using the OBD plug.  :(
Light just stayed on permanently.

If you have removed the sensor from the knuckle then chances are the retianing clip is bust and you will need a new one, the sensor very quickly moves too far away and will eventually give you another fault reading as if it were totally failed.

As a rule I leave the senor in the pin when stripping the swivel to avoid this problem.  The clip should always be renewed when the sensor is disturbed apparently.

I haven't messed with any of the sensors yet, not been able to get the ABS light to blink to find out what the fault is.

If you find a sensor out of position then light will go out next time you drive it.

Got it sorted in the end, took it down Trinity Land Rover and hooked it up to the T4, there were 6 faults stored, once we had cleared those the light has behaved itself (Fingers crossed).

Thanks all.
