EPB fault

[kenkar]

I have a 2005 S type 2.7 D. Yesterday handbrake would not release. In order to release we cut the power supply. Any one have any idea what caused this? Never had any such problem before.

Hi

If you search epb loads come up, this must come up every week

Most common when your battery gets low

You need to plug in with Jaguar software will tell you the exact fault

Going to be either a low battery, stiff hand brake cables, when the rubber boots perish they get wet and freeze this time of year, faulty epb motor or stiff calipers

Software will tell you exact fault, epb monitors position of parked and released, motor current, if these are not correct, then it faults, battery disconnect usually cures it, unless fault still there

Cheers Joe

Ok Thanks. Its not battery, I don't think, as its quite new. Calipers have new slider pins. Could it be brake module?

Hi

Caliper hand brake cable arm can go stiff putting extra load on epb motor, slider pins are for foot brake mainly, modules can go, but if it's working it not usually this and the module may need reprogramming to the can if a new one is fitted, best way is to get Jaguar software plugged in and it will tell you the exact fault,  saves any quess work, which ends up cost more in the long run, cheers

My battery is less than a year old.  Last Saturday I had "Parkbrake Fault" come up on the message centre.  It was very cold, and a quick check showed that the battery was needing a charge .  Did the usual routine  --  disconnecting the battery, and after connecting it following again the usual routine. Charged up the battery - every thing works.

When it is very cold and the battery is low EPB will tell you it os stuck on.

First time Jag owner.

I have recently bought a S Type 2007 diesel Automatic 2.7. Every few weeks it says it has a handbrake fault and the brake stays on in drive.

When I remove F20 ( electric park brake + some other things) for a few seconds then replaceit the fault goes away.

Has anyone any idea why this is happening ?

Sound like the same thing

Welcome to the club, Ian.

I have the same car as you and used to have the same fault.

The way to release it is fairly simple, but a nuisance.

You must disconnect the battery, making sure you have the radio code handy and the ignition key in your pocket.

Reconnect the battery after a couple of minutes, and the alarm will go off.  Switch off alarm and then start the car and following the instructions on the message centre [[Apply footbrake and handbrake simultaneously]

You will have to put in the radio code and reset your settings -- sounds, windows etc.

Just one thing  --  it happens to me when it is cold and the battery is a bit low.  If the battery is fully charged it never happens.

Regards,

Peter.
