we test them Jon, trust me and when you run diag w/sdd a big red x for comms on a EPB module meens theres a bad module. There ,are 2 issues er 3. rear pads too thin and this causes extended reach, motor inop, wont apply or release, and modules go bad. a Bad module can be verifyed by using the Jaguar release/apply switch that bypasses the module to apply or release the motor. If this works the module is bad there are few issues and yes a battery is one, cxables occasionally but very seldom as were talking s typo batt cables not Xtype

 

Mine was ok again for 2 days and now the issue has returned.
The code from my code reader is U01208
unable to communicate with Park Brake Module.
The Dealer I went to was an Independent
the main Jaguar Dealer was booked up.

The real issue I see is the Lack of available spares.
Even though my issue is intermittent
the inability to buy spares is causing real problems.

I really am struggling with why it comes an goes?
there were no issues on the car prior to the 4 week lay up at all for the 2 years we've had it.

 

Get one from a scrapyard / ebay / online parts seller.

 

None I can find in UK
I will have to wait till dealer has stock I guess

 

Every S-Type of your year or prior years with same electrics had one. Lots have been crashed or written off by the engine self-destroying. Sorry but someone isn't looking hard enough!

 

I had intermittent faults with my weak battery. I usually got the parkbrake fault every week or so then it would go away, but recently it came on and the car was locked up (parkbrake engaged) and couldn't move the car, turned on and off to no avail, so disconnected battery for 5 min reconnected no fault e brake not engaged. My battery tests ok on machine but it's OLD, i know it's the prob, because im not doing any resets just disconnecting NEG term sometimes for only 30 sec fixes everything until the car sits for a few days and back to faults. Im in process of ordering bosch battery from pepboys

 

You need a module, the last moduele i did for pb was intermittent and was the module. That is a communications code and that is more than not the module itself

 

And I have one of every current type used at the ready, just for that sort of testing!

If you want to blast someone based on personal experience, you have at it. Just don't use such a broad brush and paint us all that way.

Some folks make if awfully hard for us to want to help them!

Cheers,

 

As I mentioned in my PM, here are a couple of bulletins that may be of some help.

Cheers,

 

I have spent nigh on 8 hrs calling, emailing and searching
There are many variants, men being a 2007 had the latest variant.
The cheapest older variant I could find was still £100 and this was in Germany.
The 2004 model has a very different EPB module.
I rang every main dealer whom had stock listed but in fact had none.
Seems there has been a run one these lately,
https://www.dropbox.com/s/1jalqgg6t0...%2008%2022.jpg
Is the variant I have part number:c2c39403
Thanks all for your support, keeps me going

 

Steve thanks for the TSBs
I will run through them tomorrow in the light.
Mine shows the code u01208 unable to communicate with park brake module
So I never see any c codes, last time it was working here were none stored either.
It seems when it works all is fine till it fails completely.

 

DIAGNOSIS OF DTC C1785 OR C1785-00 – EPB MOTOR OUTPUT OPEN CIRCUIT.
This fault can only be detected while the EPB motor is running. If the fault is intermittent, try
flexing any accessible wiring while the parking brake is being applied or released.
To trace an EPB motor open circuit, carry out the following process:
Note: Intermittent wiring faults may exist. When carrying out the tests
below, flex the wiring where possible to provoke intermittent faults.
1. Disconnect the EPB actuator connector from the body harness (connector CA269).
2. On the EPB actuator side of connector CA269, check resistance between the
following points:1. Pin CA269-1 and pin CA269-6 (pass value 0.1 ohms to 0.2 ohms).
-–

When I got to this section
The readings were 5.5 ohms
So it looks like the EPB motor could be HIgh resistance

 

I really do recommend scrapyards and the like & ebay. There are plenty of the cars that are ex for a variety of reasons.

If you grab JEPC, free on here, you can find which type are OK but I expect it's any that's CAN bus.

 

xjrguy,

My comments were not directed to you. I appreciate the fact that folks like you and Brutal are willing to offer valuable assistance to members here on the forum. But too many dealerships are far more interested in maximizing their income stream than they are in actually finding and fixing the root cause of a customer's problem, especially when it turns out to be a comparatively inexpensive repair. Consider the number of times it has been reported here over the years that various dealerships around the country recommended ZF transmission service or even total ZF replacement when the actual cause turned out to be a weak battery. There is absolutely no excuse for a dealership to make such a critical mistake....

 

my independent stood me down as it was booked in tomorrow but no EPB module was obtained, jaguar again causing delay.
I called cust service at head office they pulled some strings and got a module shipped to the dealer
surprising what happens when you complain.
that aside I have chosen to do it myself I ordered the motor and module from the independent in staffordshire
they will be here tomorrow,
i plan to DC test the new motor first, if the readings are the same as my motor then I reckon trying the new module first will be a safe bet,
if the tests show the new motor vastly different I may plug the new motor in and see it the faults clear.
if the do then the module or motor can be returned.
if both faulty then I shall replace both.and see what happens.

I know the EPB motor is the same but am unsure if the EPB module is the same between the Lincoln LS and the S Type?

Don't think so as I learnd in this thread the module has variations on the S Type.

Anybody know?
.

There are as many versions as years the car was available.
Unsure if the latest is ok for all models?
Main difference is auto vs manual versions.

I ordered the motor and module incase either or both are the issue on mine.
Checking the impedance on the new motor when it arrives is the first step for me.

The manual says you can remove the motor without lowering the diff, but to fit the new one requires diff to be dropped 4 inches.

With chassis number you can find the part number on JPEC easily.
The motor I ordered today is the latest one superceeding the part number I have on my 2007 model.

Any advice anyone can offer greatly accepted.

 

tbird6 - Beats me. Did the LS go to CAN bus?

From the elec guides, about VIN N13089 (*) our cars moved the "park brake module" from SCP (J1850 PWM) to CAN.

(*) 2004.5MY

 

New motor and module arrived
I DC tested new motor it show 1 ohm across power wires red/green
Which was different to the 5.5 across my existing motor.
So I plugged the new motor in and checked to see if fault warnings had cleared on the dash, they had not.
I then fitted the new module with the new motor still plugged in, connected the battery again, and checked the dashboard, all warnings and faults had gone, including on the code reader.so I set about installing the new motor, followed WSM instructions apart I did not disconnect the propshaft, bit of a fiddle but the entire job took 2.5 hrs.
I then did the EPB rest procedure.
Doing the work myself saved £200 in labour costs.
I took a few pics to ensure all went back ok.
This was relatively easy in all honesty.

Thanks to everyone who sent advice/instruction and replied to plea for help.

Regards all Tony

 

Congrats on doing it yourself. Keep us posted if your issue remains fixed....
