Attached is the image of my ABS codes, my question is will the solder remedy fix this. It's one of the last mechanical gremlims I have on this car & plan to tackle it ASAP.




PS : The oxygen sensor & other code catalysts have been replaced.

 

C1095 is the classic fault for the cracked solder joints on the circuit board.

+1 on ABS module solder fix.
I had the intermittent "TRAC/ASC not available" warning when warmed up and intermittent C1095 DTC. Soldering the pump motor contacts cured the problem.
I didn't crack the case open. Instead I cut a small opening into the cover using a Dremel minidrill, soldered the two contacts and glued the sawn out back in. Taping the repair area with gaffa tape helps to keep the module safe from potential water ingress.

Good luck and fingers crossed,

I have an 97 xk8 and had intermittent then steady abs and TSC failure warning lights. The code was C1095. Replaced the abs harness but no joy. Took out the abs module, unhooking the brake lines as I wanted to flush the brake system anyway. Cracked open the module and soldered the two pins in question ( not sure the solder repair was successful as there is a poly coating on the board around the pins and I didn't try to scrape that away from the pin location). Replaced the module and flushed the brake system. I now have "check engine", "abs", "incorrect part fitted" and a red "brake" warning light showing up. Took on short test drive and I seem to have good braking but I'm thinking that I may just have to buy a used abs module, if I can find one. My part number is LJA2210AH and I'm looking. It was worth a try. Do you guys in the forum think that it is safe to drive until I get a different module?

 

The part number from Jaguar is NOT LJA2210AH. That is what is stamped on the module case but the correct part number will be JLM 20129 or JLM 20130.

You need to FIRST try to configure the module you repaired to the car. IF it will not configure because you damaged a component in the module, you will need a used replacement (new, if available will be almost $2000.00).

Unfortunately the 1997MY XK was the only year to use the JLM20129 or JLM20130.
1998 onward used different modules.
You will need to find out what module you have. (With Traction Control or EXCEPT Traction Control)
There are modules with 6 solenoids or 9 solenoids.
The 6 solenoid modules have 5 pipes going into the valve block. (JLM20129 EXCEPT Traction Control)
The 9 solenoid modules have 6 pipes going into the valve block. (JLM20130 With Traction Control)

A replacement module MAY or MAY NOT need to be configured to your car. I have seen replacements that plugged in and were good-to-go.
Other times they need to be configured as NEW modules.

Find someone with PDU, WDS, IDS, AutoEnginuity, AutoLogic etc.
They should be able to configure the module if it is not damaged.

Thanks for the clarification, Bob, regarding part numbers. A friend who was a Jaguar mechanic told me that since my car was built in December of 97 that it would have 98 parts in it. I don't know if that is true and if my car would subsequently have a different module. I have the six pipes entering the abs pump housing. I will see if my friend has scanning unit that can configure the current module. Will post the results. Thanks for your comments.

 

Oh btw I discovered this morning that I also don't have an operative speedo and cruise control. Hopefully, a reconfigure will solve the problem.

 

The 10th digit in the VID number (VIN) will tell you the MY.
V=1997
W=1998

You need to know because that will CHANGE EVERYTHING!!!!!!

Part numbers will be different (JLM20555 or JLM20556)

Charles,

I just went through exactly the same problem with my '99 VDP in the summer. Started kicking my ABS/ASC lights intermittently. After a quick scan, I saw the 1095 code and was certain that I had an issue with the ABS module. Rather than hunt for a replacement module (didn't want to deal with programming issues and the like) I decided to attempt to repair mine. You CAN get the module out without detaching the brake lines. The Jag techs may not recommend it, but I didn't have much trouble bending the lines around the module once I removed the mounting bolts - Side note - Don't overlook the smaller 2nd plug on the bottom/side of the module, make sure to unplug this before yanking the module.

Once you get it out and onto a work bench, set it face-up, take your dremel tool (or hacksaw, whichever you prefer) and cut about 1/2 inch of the way into the top of the case from the right hand side. Once you remove this piece of plastic, you will have access to the entire right-hand side of the circuit board, which is where the solder joints tend to break. I attempted to re-solder just the broken solder joints in the lower right-hand corner first, then put the unit back together and re-installed it. This did not fix the problem. It wasn't until I applied solder to all of the joints on the entire right-hand side of the board and put it back together (using silicone - or urethane - or some other epoxy of your choice) that it fixed the problem. This was 8 months ago, I've been daily driving the car ever since and have yet to experience a recurrence.

Again, this is just my experience and the infinitely more knowledgeable Jag Techs on here may be able to critique my methods, but this is what worked for me. Let me know if you have any questions and I should be able to provide pics.

Cheers,

David

 

Bob,
The 10th digit is a "V" so that would mean that I need part number JLM20130 per your information. Is that number stamped on the abs module or elsewhere. When looking for the part on ebay etc., the LJA2210AH number is what is being listed.

 

The LJA2210AH number is what is written on the case. If you call a Jaguar dealer with THAT number you get NOTHING. That number is not the actual part number in the JEPC.

You can take a chance on the internet sales with THAT part number written on the case. It should work.
You have a 1997 XK8 WITH TRACTION CONTROL (9 valve-6 pipe) so it is probably a little harder to find that module compared to the more common 'Except Traction Control' (6 valve-5 pipe).

I think I have 2 or 3 JLM20129 modules but I only have ONE JLM20130 and I will not sell it. I keep it as a swap unit for my personal customers.

It is so old that I would probably need to configure it to a car. The capacitors are old and discharged so it likely FORGOT the programming.

Keep us up to date on your progress.

I just realized that this is the X308 forum section. We should move this whole thing from post #4 on down.

Bob, I have an appointment tomorrow to configure my abs module which I attempted to repair. I also found a salvaged abs module and pump unit which is stated to be a JLM20130 part number. If the configuration of my old "repaired" abs module doesn't work then I will buy the salvaged part and hope for the best. Question: would it be best to remove the salvaged abs module from the pump and install it onto my existing pump or should I install the salvaged module/pump unit as a whole?

 

I have never disconnected the brake pipes on an ABS valve block to replace a module. The lines will bend/flex enough to gain access to the bolts and move out of the way.

I have never kinked a line but I am careful to not get too aggressive.

I would solder the replacement module before installing but if you did not have good luck with the first one, you might want to reconsider.

bob

 

Bob,
The verdict is in. The abs module that I soldered was fried and could not be configured. My mechanic had an abs module that had been soldered and he installed it for $350. All is well and working now. I would have had to pay $250 for a salvaged abs module and pump assembly and might still have had to have it configured after I installed it. My mechanic said that the module he installed was a JLM20130 as was the salvaged abs module/pump assembly. Thanks for all of your helpful information.

 

I plan on having this done this week, exactly what does the ABS configuration consist of, thanks.

 

How do you mean that?

The ABS system /setup consists of 4 wheel sensors, the ECU on the hydraulic module, a high pressure pump and a few brake hoses/pipes and wires. It also has an interface with the engine ECU, in order to perform the TCS tasks.

 

There were posts in this thread referring to "configuring" I guess that only applies to new modules being installed ?!

 

Yes.

 

Now my next question, suppose something goes awry, can the car be driven a short distance w/ no ABS module installed ?! I ask because we are doing this @ an associate's garage, & if I have to order a new unit I'd prefer my car be @ my home whilest waiting.
