Have the dreaded Parking Brake not releasing again, Had this last year and it turned out to be low battery, after recharging, it released itself. I later changed the Battery for new one, as didn’t want it happening again. Well. its back again! Have tried all the tips I can find for releasing this. When I run + & - to the Green and Red fat cables it did make a noise like it was moving for 5 seconds, but it still didn’t release. have tried this again and again, but hasn’t made any noise at all. so not moving.
I have changed the module with one the exactly the same. Still no movement.
Have ( 4 ) codes which I clear each time I try and release Park Brake. All code’s to do with Park Brake.
(1) C1094 Parking brake apply switch – circuit failure.
(2) C1782 Parking brake release switch – circuit failure.
(3) C1803 Motor disengage full travel distance not reached upon release.
(4) C1D16 High power battery feed.
Would love it to release, just cant see what I’m doing wrong. If Its not going to release can I disconnect it at the rear wheels!
Thanks

 

It sounds like the actuator may have failed internally. Take a look at this thread from a certain unnamed forum:

https://www.jaguarforum.com/threads/...e-motor.82964/

Navigation within the thread is a little irritating. Above the first picture, click on "See More" and then multiple pictures will be displayed. That shows how to remove the actuator. We still don't know if that is warranted just yet, but the pics will show the general location, etc.

Within that same thread, scroll down to post #6, showing a rusty gear. Click on the pic, and others will be displayed showing the carnage inside a failed actuator.

Should you pull the actuator just yet to look inside? Tough call. If the cables are easier to remove, I'd start by inspecting them first. I'd also inspect the outside of the actuator for general condition. If you see external corrosion, there's a good chance road salt got inside and tore up the internals. I'd also look for rust stains where the actuator gearbox halves are joined. If you see rust streaks at the seam, that would indicate a failed gasket and rust inside.
