Jon, That's not good news on any front. Sorry for the lost and hassle, but that's what we do. Lucky to get the car back for the company.
We all are waiting to see how this comes out.
Thanks, Wayne

 

...and mine.

 

It's a gorgeous weekend but due to grilling for and entertaining houseguests, I've had no additional time to mess around with my EPB issue since getting the car back from the shop late Friday afternoon. If I get a few minutes and decide to play around with it once our mini-hotel/restaurant clears out later today, I'll let you know if anything new turns up. Otherwise I'm waiting to put it back in the local indie shop next week if/when the appropriate used EPB module arrives. Stay tuned....

 

Update:

Still no used EPB module located by my indie shop, so no further testing took place this week. Maybe next week....

 

Hi Jon,


Did you or your indie guy try car-part.com? They have a searchable feature that has S-Types as an option. Also, you may want to check out the website below as they may have the desired part(s) available to ship.

Mike,

He's trying to call in some favors with a couple of his usual suppliers. He wants to borrow the appropriate module, not buy it since it may not be the issue. Can't blame him one bit for that approach. Jaguar certainly wouldn't do me this favor....

My issue is basically how long am I willing to wait. Without an operating parking brake, the car will not pass the mandatory annual North Carolina Safety Inspection. Fortunately, the car is not due for its annual inspection until December....

 

Update:

The shop owner finally located an appropriate used EPB module at a salvage yard. He expects it to arrive early next week. Once he has it in hand I'll bring my S-Type to him again and we'll see what happens once the module has been swapped out....

 

Update:

No word from the owner of my indie shop this week so I called him this morning. He's frustrated and his local used parts sourcer is also frustrated because the salvage yard that told his used parts sourcer they have my necessary EPB module (located in Virginia, just north of us) isn't responding to his voicemails and e-mails asking why he has not yet received the part. Did they not have the correct module? Did they ship it strapped on the back of a southbound tortoise? Or are they scammers? Inquiring minds want to know....

Another week passes and with Memorial Day weekend here, forget about any updates until the middle of next week. Looks like we may have to come up with a Plan B....

 

Update:

My indie shop finally received a package this morning from the salvage yard in Virginia. The packing slip says that it contains the appropriate used EPB module for my specific car. But the part is completely wrong. If the morons at the salvage yard had bothered to cross-check the part number stamped on the module they sent with the correct part number we need, they should have had enough sense to realize that they had the wrong part. We've officially ruled this salvage yard incompetent and we're now looking elsewhere. Thus far we have been unable to find the correct used EPB module. It is shared among at least three model years of S-Types and several model years of XJs, so there must be at least one of these used EPB modules somewhere in the USA....

 

What a drag Jon. Gotta hate it when you are at the mercy of incompetent people. Have you checked with Motor Cars Ltd.? Although our old friend Ken is no longer there, they are still top notch.

Jon,

That's truly frustrating!

In trying to track down my own Park Brake Failure, I've discovered that the EPB motor is running, but the primary cable is not moving, so there must be an internal failure in our actuator. I guess I'll be trying to find a salvaged actuator to fit our '04 XJR. The wrong part you received wouldn't happen to be the correct part for our car, would it???

Following all the supersessions, it looks like I need C2C17710, C2C22276, C2C24307, C2C27649, C2C28458, C2C32958, or C2C38667.

Cheers,

Don

 

If the module is making the motor run it doesn't sound like the module. Seized cable / motor / etc?

Any better if you disconnect from module and power direct as I posted a few times in this thread?

 

Thanks for the pats on the shoulder, guys....

We believe we've found the used module we need (C2C39403) through Coventry West in Georgia. We'll see what shows up when the package arrives. Fingers crossed....



Don,

The unit that the incompetent salvage yard in Virginia finally sent to my indie wasn't even a park brake module. It has already been refused and returned....

What messages are on your dashboard display screens? And is your amber warning light illuminated as well?

 

Hi JagV8,

I disconnected the actuator from the module and powered the motor from the electrical connector across the red/white and green/white wires. Applying the polarity in both directions, the motor runs both ways, but the cables and caliper levers do not move. Must be an internal actuator fault?

Thanks,

Don

 

Seized/stripped motor or bad bushes I suspect. Or I suppose the cables could be stuck solid. Module may be fine.

 

Don,

I'll ask you again:

What messages are appearing on your dashboard display, and is your amber warning light illuminated?

 

Jon,

Sorry I missed your question before. The message on the instrument cluster is PARK BRAKE FAULT, and the associated DTC is:

C1802 Greater than expected travel for measured current draw (motor current draw compared to expected number of turns).

According to the X350 Workshop Manual, the possible causes are:

Cables incorrectly routed or fixed (I have checked and all appears correct)

Rear lining wear (I have replaced the EPB pads with no change)

Service brake not correctly adjusted following lining change (I have followed the manual instructions repeatedly with no change)

Caliper malfunction (caliper levers move freely but since the cables are not tightening, the calipers don't have a chance to work)

Actuator malfunction: This appears to be my problem since the actuator is not tightening the primary cable when the motor runs. When I find the time, I'm going to pull the actuator and see if I can get inside to inspect the internals.

The schematic shows a Hall effect sensor in the actuator that must count the revolutions of the motor and report to the EPB module. My assumption is that the primary cable has become disconnected from whatever mechanism tightens it inside the actuator.

Cheers,

Don

 

Update:

The second used EPB module ordered from Coventry West last week still had not arrived at my indie shop as of mid-day today. Conventry West says that it was mistakenly shipped to Colorado and has now been priority shipped from Colorado for Monday morning delivery to my indie shop. I now believe that these used EPB modules are as real as unicorns and Sasquatch....

My indie shop owner felt so sorry for me that he ordered a brand-new EPB module from his usual new parts supplier just so we'll actually have one to test with. If my factory EPB module turns out not to be the source of the problem, I will not be charged for the brand-new EPB module. He will keep it in case we need it in the future. But we need a known good EPB module in order to proceed with diagnostics. If the second used EPB module actually shows up from Colorado, he'll try that one first. Neither of us is counting on that, however....

So we now expect the brand-new EPB module to arrive next week. Once the shop really and truly has it in hand, they will call me so I can finally bring my car back to them so they can get back to finding and fixing the issue....

Stay tuned....

 

Update:

The used EPB module that Coventry West mistakenly sent to Colorado miraculously showed up at my indy shop yesterday afternoon. So I dropped my S-Type off at the shop this morning. We'll see if the used module will allow their diagnostic system to read whatever codes have been thrown....

 

Update:

The used EPB module from Coventry West did not work properly....

But the brand-new EPB module that arrived yesterday fixed the problem. It identified about a dozen codes that had been triggered when the factory EPB module failed. The shop systematically cleared the codes and then reprogrammed the new EPB module to clear the CAN bus error that had occured. The "Park Brake Fault" and "Cruise Not Available" messages then disappeared from my dash, and the amber warning light turned off. The shop wants to keep the car until tomorrow to ensure that everything remains clear in the morning when they crank it up again after it sleeps overnight. Fine by me - I would much rather be safe than sorry....

They used their AutoLogic system to diagnose and repair my issue once the new EPB module was installed. I don't have those resources so there is no way I could have successfully accomplished this repair myself....

Thanks to all who contributed ideas and suggestions in this thread. I will keep you posted once the car is back in my hands and I put a few miles on it....

Lesson learned: Do NOT rely on used electronic modules. It takes forever to find them and when they do show up, they do not work....
