I'm going to check the FAQs and hope this is a common problem, but my girlfriend's 2005 S Type was in the garage at the hospital all night where she works and it was the first freeze (25 degrees) we've had all year in Texas. I don't know if that has anything to do with this or not, but I thought I'd throw it in.

When she got in the car the electric parking brake would not disengage. The screen on the panel said something about 'engage foot and parking brake' but she could not drive the car. Someone came by from roadside assistance, hooked a computer up and released the brake. Now the brake no longer works, and it says this message on the gauge cluster, and beeps like mad anywhere you drive as it believes the parking brake is engaged all of the time.

I'm assuming this is probably some sort of solenoid which interacts between the electric switch and the hydraulic brake system, or maybe something as simple as a faulty microswitch.

Can anyone assist here? I can certainly replace the part, bleed the brake system, etc as necessary, I'm just not at all familiar with this brand (it's a great car, but I grew up with BMWs!)

Thanks for any assistance! If someone can REALLY help me out I'll shoot some PayPal cash their way!

Well, I'm not an expert on this but here is something you can try that might work. Disconnect the battery for a while and when you reconnect it you should have to recallibrate the parking brake. That might do it, or you battery could be on the way out. I know with mine, when the battery gets low and needs a charge in the winter, the park brake won't go on (opposite of your problem). But with a fresh charge it works fine.

 

The reset procedure is listed here. https://www.jaguarforums.com/m_75851/tm.htm
I replied to a previous thread.
Hope it helps.

 

Thanks a million guys! I'll give it a shot!

 

where are you in Texas? and the battery reset probobly is not going to work on you problem, the most common failure is the park brake motor, and it above the differential and a pain to replace even on a lift. when the motor fails the Park brake module knows and beeps for along time to get your attention(like you dont notice already)

 

Jaguar has been laid up for 4 weeks
Today on its first drive again
I have got the following:
Park brake fault message
Cruise not available

The hand brake is not working now,
I tried disconnecting the battery for a short while, this made no difference.
Performance is not affected.
Whilst the car was parked, the handbrake was left off,
All appeared ok for the first 10 miles of the drive then the park brake fault message popped up and the cruise message soon afterwards.

Can anyone give me some pointers, before I have to head off to the dealers to lose a wad of ££
Thanks in advance

 

Vehicle most likely needs park brake motor if hard reset and calibration does not fix it.
Common problem.

 

Or it's a low/duff battery.

 

Just thinking back on 2 cars i worked on with park brake faults. They did have bad batteries and that was the problem. Sometimes the park brake would lock up. Have battery tested.

 

Thanks for taking time to reply I will check battery first.

 

+1 on battery. Give it a long charge but replace if that doesn't work.

 

Charged Battery fully
and normal service has resumed
Thanks you all for replying.

 

Well that didn't last to long (
So I suspect the battery is shot!
As when I put the charger back on it was taking full charge again after going nowhere.
I will charge it so I can move it as the park brake is now locked on.

 

If you can get it charged enough you can then release the EPB by switching to ign II (or starting engine, if it will) and pressing paddle. You can prevent it reapplying by holding the paddle down as you remove the key.

 

If a battery doesn't mend it, please heed Brutal's question above: I'll go a step further: if u are closer to the Houston area than DFW, contact Brutal, closer go DFW? Motorcarman! I've had good luck w/ Autobahn Jag in FtW but mostly use parts, rarely svc and then only b4 finding Motorcarman.

 

new battery same issue
unlocked parking brake with 12v onto the control wire on the EPB plug after taking it]
out of the Module
so at least I can move it

 

I'm guessing Somerset is the one over here (England) LOL

 

PARK BRAKE FAULT light problem happened to me 2 years ago. I had to keep turning on the ignition until the light would go out and release my shift stick locked into the PARK position. I read many mechanic replies on a couple different Jaguar forums and started worrying about the $$ this troubleshooting repair process would cost me. But then, one very brilliant mechanic offered the easiest fix to try first.....AND IT WORKED PERFECTLY!! Here is the FIX:
The sensor switch for the PARK BRAKE FAULT light was designed ONLY TO OPERATE AT FULL BATTERY POWER of 12 watts. I often leave my 2005 S-Type covered in a parking location for weeks at time to help preserve its life and beauty. BUT....when I checked my 12 volt car battery with a charger unit with digital meters on it, I saw my car only had 11.2 volts stored up. So...I charged it up for about 2 hours (time will vary depending on your charging unit). Then, with the battery fully charged, the car began starting perfectly every time. 4 months later, the same error light showed up on my instrument panel, and I charged up the battery again: SUCCESS! When I realized I had been using the original 2005 battery that came with the new car - and it was now 2016 - it was time to buy a brand new battery! And I've never had the problem since. I also drive my car a little more often just to keep fluids flowing and the battery charging! I have since heard from other Jag folks that there are a few other auto sensor switches in the car that are extremely fussy about demanding a full 12 volt battery to operate correctly.

 

Jesus this is a old thread i replied to 9 years ago. Always make sure your battery is good. Now the biggest issue that the cars are no longer anywhere close to new

 

This is the first thread I found regarding my current park brake fault issue. I replaced my battery last year to resolve an unrelated issue. The new battery didn't solve the problem, but my battery was very old and needed replacing anyway

My problems with the park brake are seasonal, which is a clue...
