Wiring Diagram(s) for 1.9 TD Xantia Reqd

Unread post by steviewonder7 »

Hi Folks,

Can some kind soul point me in the right direction so I can obtain some really
decent wiring diagrams for the Xantia 1.9 TD mk1 1994 with abs.
Ihave the Haynes BOL which is very limited to its deph/scope of wiring diags.

I have an abs fault and believe its wiring related. I've gone down the usual routes as per problems/answers in this great forum,but to no avail.

So any pointers would be greafully appreciated.
Thanks in advance to your replies.

Steve :)

When you say you've gone down the usual routes, are you 100% certain
the sensors are reading correctly through a multi meter and the air gap
between them and the CV knuckle is within tolerance?

It is rare for the ECU computer to fail too - what is the failure symptom
with the warning light?

The haynes wiring diagrams are actually a straight lift from Citroen's own
factory workshop manual!!

True, but they only show the 1st part of the diagram. citroen diagrams come in 3 parts & the second part is more detailed & shows the routing of the wires & if they go through any interconnectors & splices. the 3rd part shows component locations.

Thats the thing....I dont get any warning lamp(abs) at all.The lamp doesn't
come on when turning the ignition on prior to starting.And yes I've checked all the lamps in the dashboard ,even renewed them for good measure,again testing them prior to fitting. plus all fuses are good.I just dont seem to get a feed up to the lamp(abs).
Looking at the BX diags they show diodes in the circuit,even if the diags are related to the Xantia ,at the moment I cant seem to locate the diodes.I suspect maybe these could be at fault.I just want to eliminate them for good measure.So iwas just wondering if there were other more substantive diagrams out there that may help.

First thing I did when I got the car was to check all fuses and replace any that were missing - that's when I discovered mine had (faulty) ABS :oops:

From memory, I think there's a related fuse under the bonnet but don't quote me on that. I've just pulled the under dash fuse (#7?) to kill the irritating dash ABS light.

I think the Xantia ABS system is different from the BX one and I have been told the the first generation of ECU used (to 96 or so???) was prone to failure.

The thing may be capable of repair and can be tested by specialists many of whom no doubt can be found on the net.

I replaced the abs ecu shortly after finding I had problems with the abs system.Its been repaired by a reputable company I found on the net.
All the sensors appear to be o.k with the correct readings(I replaced two,one front one rear).
I also cleaned up the cv joint abs rings and the rear arms,then checked the air gap between ring and sensors,so i dont think these are the problem.
So it doesnt leave too many more options open.

Shhhhhhhh....

just don't tell Mr Citroen... :wink:

I happened to accidentally stumble over these that you may find useful:

BB00 - Battery
BB10 - Supply box
BF00 - Fuse box
0004 - instrument cluster
2100 - stoplamp switch
CA00 - Anti-theft switch
7000 - LH front ABS sensor
7005 - RH front ABS sensor
7010 - LH rear ABS sensor
7015 - RH rear ABS sensor
7018 - Road wheels ABS relay
7020 - Road wheels ABS ECU
7040 - Additional Regulation Unit (GRA)

Don't say I gave you this!! :D

It does sound like a significant power supply issue - I'd check
the consumer unit distributing the power through big fuses and
relays in the box beside the main battery first. I'll see if I can
locate the map for this too...

My 'friend' ICO1 has caused me all kinds of grief on two Xantiae
now with one car losing it's lights and the second it's whole ignition
circuit... :shock:

That's just with the cars sitting unused minding their own business too!

I see your problem with Haynes - when it comes to the wiring diagrams ABS was all too difficult for the guy who wrote the book so he pretended it didn't exist.

However I don't think the author of the French Revue Technique had the same problem. Try page 70 of the diesel book -

and follow link to Xantia Diesel.

Thanks for that guys,hopefully its just what the doctor ordered.
I'll study the material in great detail later. :D
If I find the cause of the problem I'll let you know.
Thanks again for your time and trouble

Hi Folks,
It seems that I've managed to cure my ABS fault :o
The thing is ,it wasn't what I expected.I had a look at all the wiring in the engine bay,under the plasic arches under the front wings,took the wiring out of the convuluted plastic sheath covering the wires that are routed under the radiator(seems like someone has been there before) and messed with all the earth points behind the battery.
I checked the Abs connection to the abs ecu again(found nothing obvious),checked that horrible (brown/grey)connecter attached to the inside of the left inner wing and after all that had the dash out again,all I might add to no avail.But.....the thing is the abs ,as of yesterday, appears to function when the car is sat staticly.
The abs lamp comes on straight away when the ignition is switched on and soon goes out shortly after starting and running the engine......Hoo bl***y ray :shock:
All I can say,apart from being relieved,is that the fault may all be down to a dodgy connection somewhere,where your guess is as good as mine :?
Anyway the next test is when I get the car mobile on the road in the near future and test the abs for real.
Thanks to you folks who helped with your input on the matter.
Regards Stevie :)
