Couple of things Jon.

Congrats on resolving the park brake issue. I would have never guessed that your very well, southern maintained '05 S Type would need such a module.

Might I inquire what the new module cost? Alldatadiy stated something in the area of $1,200.00 (US).

Lastly if you feel like it would you send me your old module, or hold onto it until we meet again? You know I would enjoy dismantling the darn thing, just to see if there is any visable burnt traces or such.

 

Rick,

Thanks for the kind words....

My cost for the new EPB module is $318. Don't know what the labor charges will be yet. I'll let you know after I pick up the car....

The shop owner asked for permission to tear into my factory EPB module when we spoke on the phone a couple of hours ago in an effort to discover what went wrong with it. I gave him permission to do so. If he decides not to (or simply does not have time), I will grab it and hold onto it for you and me to explore when we get together again to do that final ZF drain-and-fill on my S-Type later this year....

Several weeks ago I called ASI (they repair power seat modules, ABS modules, etc. for $60 or so) to ask if they also repair these EPB modules. They have never done one before but are willing to do so. Since it will require significantly more time on the bench to get through their learning curve for diagnostics and repair, they quoted me $189 with a one-year warranty....

 

Congrats, Jon! Wow, what an ordeal.

 

Good news Jon.

 

Update:

My electric park brake system continues to function normally today. I plan to pick up the car later this afternoon....

Here are the fault codes that the new EPB module allowed the shop's AutoLogic system to read yesterday:

C1094-00
C1782-00
C1785-00
B1318-00
U0001-87
U0100-00
U0103-00
U0121-00
U0155-00
U0401-00
U0415-00
U0422-00
U2001-68

Kudos to Toby Briggs at Flying Circus English Cars in Durham, NC for all his efforts during the past month in finally getting this issue resolved for me. Great guy, great shop, and as customer-oriented as you will ever find. Thanks again, Toby....

 

I just checked the fault codes listed above on my JTIS CD (which covers through the 2004 model year). My S-Type is a 2005, and the only one of these codes that appears in my JTIS CD DTC section is B1318(00), defined as a Dynamic Stability Control error due to battery voltage being out of range (low)....

Can anyone supply the meaning of the other codes in the above post (3 "C" codes and 9 "U" codes) for a 2005 S-Type?

 

I'm not near any DTC meanings but the -nn are fairly new and are a subcode showing the kind of thing wrong, such as short to ground (with 00 meaning no info).

Thanks Mike. Looks like three or four of those code descriptions you found apply to my case. Perhaps I can eventually gather enough information to speculate on why my factory park brake module failed. That may help someone else down the road. These modules were also used in the XJ sedans built at the same time so you may want to keep this info handy in case you need it. Don't waste time pursuing used modules - spring for a new one. But it will have to be programmed to properly synch up with your specific car's system so that must be done by a shop with the necessary equipment to do so. In my indie shop's case, it was their AutoLogic system....

 

Jon, still curious as to what the price is of a new EPB module.

Your price was $318, but I seem to recall that maybe the shop gave you a "deal" as you had suffered so much? And I saw another figure of ~ $1200.

So, what could I expect to pay? After your experience, there's no way I would want a used EPB module.

 

From Gaudins Site,

CONTROL MODULE - 2003 Jaguar S-Type (C2C33376)

• List Price: $308.00
• You Save: $38.50 (13% off)
• Sale Price: $269.50

 

alldatadiy.com estimated the module at $1,200.00

 

Yep, these park brake modules typically run $310 to $330 retail depending upon the exact part number you need (and getting the exact part number specified is critical). SNG Barratt Group quoted me $275 but that did not include shipping and they needed a week to ten days to source it from the UK and then get it to me. I opted to purchase the brand-new module that my indie shop ordered on their dime in case the used module from Coventry West never showed up or did not work. That was the least I could do for my indie shop owner going out on a limb for me....

I'll say it again - do not waste your time chasing used modules for this repair. They just don't work....

 

As some of you know, Jon, Wayne and I spent the morning servicing Jons ZF gearbox a couple days ago. Somewhere in this thread I had asked Jon if I could have the old brake control module that was replaced. Jon brought it with him.


The control module was very easily dismantled, 4 Phillips screws and the circuit board slid right out. In the following pictures I was able to find what I believe is the burnt trace that caused Jon his headaches. At fist you will see the circuit side, where the burnt trace is, pictured in the red circle. It was very tiny and hard to see with these old eyes, I took a tooth pick and barely touched at what looked like a very tiny blister on the board next to the capacitor. The tooth pick "opened" up the blister revealing the burn. The flip side of circuit board shows no sign of any damage.


Jon mentioned in this thread that the controller has to be programmed to the vehicle. Bummer, I would like to solder the trace back together and see what would happen. Maybe I can send it back to you Jon and you plug it in??????

 

Hey Rick,

I hope you did indeed find the cause of my original EPB module going belly-up....

But the only way I would risk plugging it back into my car would be if my replacement EPB module happened to fail. I sure hope that doesn't happen, though. Getting this issue resolved lasted from late April into early June and took us through two attempts with used EPB modules that were supposedly correct for my car. Only the brand-new EPB module finally fixed it. Lesson learned....

So repair that burnt trace you found, store the EPB module in a cool, dry place, and if joycesjag's original EPB module ever fails, since both of our cars are 2005 S-Types try my repaired one before you do anything else....

 

Hi,
This is an old thread, but I am going through the exact issue that Jon described. Would you still have the EPB that you repaired? I can try it on my S Type 2005.
Thanks

I am not to sure if indeed I took Jon's advise and tucked it away. I will have a look for it in a little bit. Check back here in a few hours from now.

If I have it, it's all yours.
