The important question I have here is if there is any difference between the front left ABS cable and the front right one. Is the left one shorter? I believe the correct part nos. are
FRONT RIGHT LJG3410AC or LJG3410AB
FRONT LEFT LJG3410FC or LJG3410FB
Anybody know if these are the correct numbers? Or confirm whether or not the left cable is shorter than the right.
Problem is that I need the right side cable and I can only find reasonably priced left cable. (Quotes of around 120€ for a simple cable less than a meter long I find ludicrous).
I'm hoping that somebody can tell me they are the same length or tell me where I can find a reasonably priced front right cable.
The reason I am first of all going to try with a new cable i will explain.

Having finally managed to remove and replace both ABS Rotor Rings (see my other post) I am now faced with the next problem. I am getting now a C1145 error indicating a front right wheel sensor circuit failure.
I live in Hannover and we have here fortuanately (?) a specialist ABS control module workshop. Took the XKR over to them this morning and the technician connected up his diagnostic gear. The diagnostic showed him the C1145 error. He then fetched a short piece of cable with a standard sensor attached and connected this to my cable harness under the bonnet. He was therefore excluding my cable and sensor and simply getting a reading from presumably a working bit of cable and another sensor. At this point he told me not to look over his shoulder at what he was doing. After a few seconds he asked if the ABS warning light has gone out. It had. He packed his gear up and refused to discuss his findings with me. He said I must speak with his boss who eventually came out having no doubt heard his diagnosis.
He strangely didn't explain what was wrong with the car but simply said that they would repair the ABS control module for the bargain (?) price of €341 and added that as the cables often were faulty on Jags there may be another €100 or so added to replace the cable.
Have any of you guys ever been told by a mechanic to turn away stop looking over at what he is doing? This very strange behavior leads me firmly to the conclusion that I am going to be ripped off if I go ahead at this workshop.
Therefore i really must fit a working cable to check before proceeding with a more expensive repair.
And BTW I bought first of all a new sensor and have indeed changed the sensors left for right - all with the same result.
Hoping to get some interesting feedback on this. Thanks in advance

 

bouncer99,

Last year I had Fault Code C1155 on my 2003 XKR, which was a failure of the ABS Sensor Harness for left front wheel. This is common failure because the cable receives a lot of movement from steering and suspension. Confirm that I replaced with LJG3410FC and it worked.

I don’t know for sure if the left and right Harnesses are the same length, but from inspection I believe they are different. When you look at the Harness connector on the Right side inner wing, it is moved into a different position to the left side (not symmetrical). This is to make room for the Air filter box and may account for more cable length after the grommet through inner wing.

 

First order of business would be to consider not do business with them again, it seems. Even if he was entering a password, that doesn't seem like a 'healthy' interaction during his diagnosis or later.

And yes, right part numbers. You can do a continuity check on the cable(s) to determine if there is a break (check resistance across wires with a voltmeter, or bridge one end and check resistance across the whole harness). Could be what he did.

The fact that the light went off while he was doing something seems like more of an indication that he found a continuity problem with the cable, but who knows? I will observe that it's hard to reach into the module to 'temporarily fix the pins' without taking it out and permanently fixing the pins...

 

bouncer99,

As crbass explains, the cable can be checked for continuity. Here is a video from 'to the garage' showing exactly how to do it

 

Have you tried swapping the wire harnesses as well (fender connector to sensor)? If there is a permanent code, it would seem like the cable is permanently broken, and should be easy to test for simple continuity with a meter. Swapping the cable should lead to a different code, confirming the diagnostic. I would also make sure that by plugging in the known good cable/sensor in the known bad connector, the current error code still goes away...

For parts, check SNG Barratt, our forum sponsor.

 

Can you share the last 5 digit of your VIN? Did your car call for LJG3410FC or LJG3410FB? My car is the earlier batch, calling for LJG3410FB, which SNG lists as "turned down". I was hoping LJG3410FC would work, but SNG does not say FC "superseeds" FB. The cut-off is listed as VIN 36874. Thanks for any input.

 

fmertz,
My VIN last 5 digits are 34120. The car was manufactured Jan 2003.
It did call for LJG3410FC and works fine.

 

Well, I have now replaced the cable for the front right sensor and the C1145 error has gone. This seems to be the proof then that the ABS specialist workshop which i mentioned above were simply trying to rip me off to the tune of at least 350 Euros.
However, all is not so simple with a Jaguar.
I am now getting a C1141 error. 'Front Left Wheel speed sensor tone ring missing tooth.This is not possible as i have with enormous difficulty fitted new sensor rings on both front wheels. I have seen this message in the past with the old tone ring which was very rusty and may not have been being read correctly. Maybe the sensor is not sitting correctly or not bolted tightly enough but I cannot be bothered to look today.
Any suggestions for me to ponder about before I start solving this tomorrow?

 

What i forgot to mention above was that at all times the wheel speed could be read in my diagnostic. So all working but a C1141 error.
I have actually gone back to the car to try the battery dis-connect trick. Big mistake.
Went for a short test drive and now there are no speed readings for either of the front wheels and error messages from both wheels.
I'm beginning to think that the ABS module is suspect. Help! Comments! Anything!!

 

bouncer99,
Based on your original Wheel speed error codes, you have done everything right.

You’ve changed; Both front ABS Rotors, Both front Wheel Sensors and Front right cable. Yet you’re still showing the same front error codes. I think you are right to suspect the ABS Module because it’s upstream and there’s nothing downstream left to change !

You should do a continuity check on your original left front cable.

I assume that, rather than just a Battery reset, you did erase codes to clear them diagnostically?

I’m at a loss and very interested to see what the forum experts recommend next.

 

So apologies for such a late update.
Actually I had only checked the front right cable and found it to be OK. Finally after renewing both front sensors and renewing the driver's side cable all worked as it should.
Continuity was fine on the original cable so I fail really to understand why it eventually worked with a new one. But, here we are 4 months later and the problems are definitely a thing of the past.
My thanks again for the help and encouragement above.
