Electronic Deployable Towbar

Post by MiCoHi » Wed Nov 27, 2019 6:22 pm

Ok, so I've fitted the above to my 2018 F-Pace today - quite easy really - pleasantly surprised at how easily the boot side trim comes out to fit the wiring and extra module, as I've never really worked on Jags, only Audis.

Anyway, I followed the instructions, put the car in service mode to avoid triggering a theft alert when I removed the battery positive connector and the loom and module went invert easily, as did the speaker and switch. I've not actually fitted the towbar armature yet as it was raining and I didn't fancy getting the bumper off in the rain, so for the time being, I've laid it in the boot and hooked it up there.

Now to the question: I know that I need to get the car hooked up to SDD and have the EDT module recognised by the car, but is is to be expected that in the meantime, there'll be sporadic failures of other functions? At the moment, I occasionally have a message flag up on the dash that there's a dipped beam fault and also that IEB is not available. ICTP also turns off randomly and then powers up again within 20-30 seconds. The car drives fine through and all lights work (bar indicators when ICTP is off).

The boot switch doesn't work to deploy the bar or retract it either, so I presume that the car's CANbus needs to learn that the EDT is actually there?

Any help greatly appreciated, including any offers of coding! If only Jaguar made their coding as openly available as VW group - I have full, genuine VCDS for doing that to my Audi.

I thought MY 18 was the new pathfinder software not SDD?

My local dealership won't install this for me because, even though I have the genuine Jaguar parts, they weren't all bought from a main dealer. So if you have any pictures you can take along the way, that would be great as I am thinking of doing this myself as well.

The dealership did however say they would be OK to hook it up and upgrade the software options for me once it was installed though.

I'll take photos for the bumper removal which should assist you. The interior boot trim is really very easy to remove - just do the following:
  • take out the boot floor panel, spare wheel if you have one and the polystyrene foam for the tools and the battery cover one (you may not have one if you've no spare).
  • Put the car into service mode using your Jaguar app - it prevents you from getting a call from the tracking centre when you disconnect the battery positive terminal
  • Remove the positive terminal (10mm socket needed)
  • Peel off the rubber seal from around the boot opening - only need to take it off from the parcel shelf level to the lower right corner so you can get the scuff plate off and the side trim. It literally just pulls off by hand
  • Remove scuff panel from around the lock hasp - there's 2 x 10mm nuts need undoing with a socket and then tug it sharply upwards and it'll come away easily
  • Remove the 2 x anchor points on the left side (mine were a bit weird - a 5mm hex key was a touch small, 6mm too big)
  • Remove the 3 x cross head plastic screws (1 revealed when you take off the scuff plate) that hold the carpet panel next to the anchor points
  • Behind the rear seat release lever, there's a T30 screw - remove it and then carefully but forcefully tug the plastic panel away - Unhook the release cable and the connector for the light there. This can then be left swinging in mid-air - no need to remove fully
  • Remove the 4 x plastic studs revealed after you've taken the previous panel out, get a flat blade driver in there and wiggle out. Do the same for the bag hooks - there's a strip along the top which pulls out first and then the hooks just pull out.
  • The entire side carpet panel then can be swung out and you'll see the area where you need to install the EDT module and cabling. There's a blank plug installed in the grey power/CAN connector which must be removed before you hook up the loom. It's all pretty slick in the way it fits, but I placed a piece of extra padding between the loom and the metal fixing for the anchor point as I didn't like how tight it was to the bare metal edge.
You can install the speaker, switch, EDT module and loom then just leave the armature ends in the wheel well and put everything back. You then just have to take off the bumper and feed the 3 x connectors for the armature through the big hole in the wheel well and hook it all up underneath the car.

I'm a little baffled by the way in which the car is randomly showing errors, but I guess this is normal as there's something new on the CAN bus which it doesn't recognise yet. I'm also a touch concerned that the armature isn't deploying when the boot switch is pressed - I'd have thought it would work regardless of coding.

Guys did you get it working? Did you buy the towbar off ebay?
I did the same thing at around the same time as you, I’ve had it professionally installed and coded by jlr however the towbar is just floppy it neither retracts nor deploys, I would greatly appreciate any guidance, brink won’t help, jlr won’t help, next step is to remove it and pass it to some electrical maintenance guys to see if they can get it working.

I've not had chance to have the car coded yet, but hopefully, I'll be doing it in the next month or so.

When you say your bar is floppy, does it actually move around? Was it floppy when you got it? My hook is firm and secure in the stowed position at present. It does sound as if the motor in your armature is defective in some way and has left the hook in neither a fully stowed or fully deployed state, which is what one of the two motors in the armature does - there are two motors, one to move the hook, the other to move the latch.

When I got it the tow bar was firm and fixed in the retract position. When the guys installed it it remained fixed in position, the switch in the boot was illuminated but did not do anything . no other errors.

After some ringing around inc Jlr independent specialist , only jlr can do the coding.
When I picked the car up from jlr they confirmed coding and calibration all done but still not working.

When I went to the car the towbar was hanging floppy. Switch in boot led flashes rapidly and when pressed very brief wurring if the motor, error bleep and that’s it.

Any pointers to a drawing or video of how a brink unit works would be really useful

All fixed in the end with no help from Jaguar or Brink at all.
One of the motors in the armature had broke, replaced. Now all works as it should

Finally fitted mine this weekend. Slightly more involved than I had bargained for - I found getting the exchaust brackets off one of those jobs that took far longer than it should have done.

Also the supplied bolts started to round off a bit before I hit the target torque, I would have expected them to be tougher. Maybe I had a socket 1mm to large? I suspect they are 18mm, but i only had a 17mm & 19mm in my socket set.

Anyway, all back together but not re-mapped the ICTP due to JLR being closed. Apart from the deploy button not working (expected by previous posts by MiCoHi) I now do not have my parking sensors working. Any thoughts if this would be fixed by the remap or do I need to get the bumber back off to check my connections? I can't seem to find a relevant fuse specifically for them to check if I have blown that.

So are JLR happy to code these things if they didn't fit them?
