If you feel brave, this was released on 16 DEC 2018. They still do not know the true cause of the Blank Screens. They are collecting surveys from techs who are working on the cars to try and isolate it. But to try and 'fix' the problem, JLR is telling their techs to:

Reset Procedure:

1) IDMA Reset:
Pull Fuse 1 (15A) from the QUIESCENT CURRENT CONTROL MODULE, located Right Hand rear quarter trim panel
If this resolves the issue please, reset is complete.
If issue is still present continue with step 2

2) IMC Reset:
Pull Fuse 5 (15A) from the QUIESCENT CURRENT CONTROL MODULE, located Right Hand rear quarter trim panel
If this resolves the issue please, reset is complete.
If issue is still present continue with step 3

3) SICP Reset:
Pull Fuse 15 (15A) from the QUIESCENT CURRENT CONTROL MODULE, located Right Hand rear quarter trim panel
If this resolves the issue please, reset is complete
If issue is still present continue with step 4


4) Quick power mode cycle:
Turn Ignition off
Wait for 15 seconds
Turn Ignition On
If this resolves the issue please, reset is complete
If issue is still present continue with step 5

5) Quick sleep cycle:
Turn Ignition off
Single lock vehicle
Wait for 10 mins
Enter Vehicle
Power on vehicle. Start vehicle (Press brake pedal, Ignition on).
If this resolves the issue please, reset is complete
If issue is still present continue with step 6

6) Battery hard reset:
Remove 12V Main battery (T4) negative terminal.
Wait for 10 seconds.
Connect 12V Main battery (T4) negative terminal.
If this resolves the issue please, reset is complete.

Still nothing? Escalate.

Do you have any pictures of this module, and how the fuses are numbered? I see two boxes behind the cover that have fuses in them, neither have fuse numbers on them.

I tried pulling the 3 fuses I circled in the photo, but no luck. No luck with steps 4 and 5 either. That leaves step 6, disconnecting the negative on the 12V battery. But it's raining too hard right now so I'll try that later.

I can't find maps in either the Owner's Manual or Service Manual, just lists of fuses and fuse box locations.
Did you look at the bottom of the cover? Many cars have a map underneath the cover.

There are 5 fuse boxes. One you do NOT play with (center under bonnet).
Left and right sides under bonnet.
Under rear seat.
Right side of the cargo area.
Your owners manual shows where these are.

When I checked the owner's handbook it mentioned one loadspace fuse box, but there are two. The one in the manual doesn't list a fuse in position 15, and fuse 1 is 20AMP, so I figured it was the other box. Googling for "i-pace quiescent current control module" got https://www.ebay.co.uk/itm/JAGUAR-I-PACE-FUSE-BOX-FUSES-ELECTRICAL-SYSTEM-GENUINE-NEW-2018-C2D23644-/163121346422 as the first hit and the module in the photo matches the second module (towards the rear) in the right rear quarter panel. Counting from bottom left to right and top right to left gave me 3 15AMP fuses in spots 1, 5, and 15. Looked like a match, but didn't help, and put a warning message on the console. Traction battery failure or something like that. I'll go drive it around for a bit to see if that clears.

What is the source if this troubleshooting list? You know someone that works at Jaguar?

Jaguar Land Rover (JLR) has TOPIx as their on-line service information service. It's a subscription. I paid for a month looking for information about updates and other info. Most the information I expected to find is not there, or I can't locate it with their search function. Like the trailer hitch and wiring, how to acquire the Pathfinder tools (reprogramming), or vehicle specifications.

Thx for the info.
Have you had the touch screens go out and put the troubleshooting steps to use with any success?

Thx for the info.

When my touch screens first went out, all I had to do was a 100% charge, lock and unlock the car, then do a Slow Boot.
I get in, put on my belt, hold the brake and push the ON/OFF for a full 1 second. Now I wait for the car to boot up.
It will load the phone stuff, then music, then nav, then 4G, usually a Jaguar warning screen comes up, and I tap it.
I would not plug a phone into it until it's done booting, or put/remove a memory stick while booting.
When everything is up, then I put the car into gear.

Since I've been doing that, (often ignoring the 100% charge and 4G), I've had no black screens or sudden switch to Celsius on the temp knobs.

I'm very used to computers taking awhile to boot. You should see how long an iPhone takes to come on when it's been turned off. And after many years, they still have serious bugs in it.

Sadly, I remember when a 80486 booted too fast and you had a TURBO button you had to have OFF in order to get it to boot. Virtually instant. Lotus 1-2-3 spreadsheet was just over 0.1 megabytes. It fit on a floppy. I'm not convinced today's computers are much faster than what we had when it comes to Work Per Hour. We just have bigger programs that are not optimized.

Perhaps the reason the I-Pace boots slow is it does some things that some other cars do not.
1) Hotspot
2) Carplay and AA
3) Smart climate controls
4) Does the diagnostics BEFORE the motor is turned on, ICE does it afterwards. You don't want >400v active until you've checked it first. You can't check an ICE unless it's running.
5) 4 LCD displays: HUD, Dash, Center Top, Center Bottom.
6) Runs under Windows. Linux is far faster especially on multicore machines or machines with less ram.

I get in a drive the car like any other car. I don’t give it any extra grace or special handling and in >3400 miles it has done just fine. In the couple times there have been blank screens, they have self resolved within a minute or so of driving. I think one time they lasted for several minutes, but I made a quick stop to get a drink from the gas station and upon restarting everything was fine.

Picked up my First Edition yesterday. Drove like a dream. This morning when I went in to start it up, the center two screens didn't come on. Tried the slow start method--didn't work. It still drives fine, just the screens are out. Have tried to see if it would resolve itself about 4 times today on various drives but they've stayed off. Have it on the charger now, will top it to 100% and see if that does anything. Not really that fond of messing around with fuses, but will take it there if the problem persists.

Sorry to hear #Pseudonym, yesterday I just crossed 1000 mi on my FE. Other than a rear camera view that 'stuck' on once (even while driving forward) until I hit the home button, I've had no blackscreen issues. What TouchPro version do you have? S18C or S18D? I'm still on S18C but elsewhere in the forum owners have reported "D" installed or updated by dealer (OTA not available yet?). Otherwise, my InControl app *has* frozen up (lost connection to car) a couple times, but charging the vehicle did reset that connection.

You have seen McRat's blackscreen checklist posted in this forum, right?

I do have 18D installed. I haven't messed around with pulling fuses yet but that is next up on the agenda. Charged to 100% last night and let it sit for 16 hours, this morning the screens still were blank. Interestingly I can tell the main screen is on, with no graphics, whereas the lower climate screen is completely off. I can't adjust the climate and its apparently stuck on blast furnace hot. :(

When the center screens wouldn't come on, I couldn't adjust the climate controls, the displays in the climate control buttons didn't function, and there was no way to play any audio or use the navigation. At some point I noticed that the top screen would show a power icon and the camera, parking assist, and auto park icons, but it didn't respond to tapping except for the power icon which turned the screen off. Two days after the center screens went out they came back on shortly after I started driving. I had scheduled a service appointment, but have cancelled it now that everything seems to be back to normal. I do recall that shortly before the screens went out the system had also lost the smart profile I created. That didn't come back, and I haven't recreated a smart profile. It seems a waste of time if it's just going to disappear again anyway, and I'm not sure what settings it remembers that aren't in the "default" (dumb?) profile. The traction battery fault warning that I got after pulling the fuses is gone too now. Never did have to disconnect the 12V battery. I did push the service button on the left side of the rear view mirror until it started blinking slowly several times, with no immediate effect, no idea if it made a difference.

I agree with the waiting approach. I haven’t had any screen blanking issues since I started giving the screens a little time to boot up.

Tried steps 1-5, off to try 6. Wish me luck! My dealer claims they have no loaners and keep putting me off until they do so this is where I'm at. 6 of my first 7 days as an owner without functioning screens. :(

I ran into a blank (upper) screen today after stopping during an errand run. The climate screen was still showing and responsive though. I didn't have time to try to reset procedures, but I did do something that got the top screen to come back.

Try using the voice control to tell the car to dial an incomplete phone number. When I did that it showed the screen control dialog to let me finish the number, and instead I hit the X in the upper right of the dialog. Once I did that the upper screen came back and was normal.
