I know there are many forums on this problem of the Three Amigos but i am in serious need of any advice. I cannot find anything that 100% applies. This vehicle has had these lights for some time and i cannot figure out the issue and neither can a garage. Here are the faults from my IID tool:

IPC-Instrument Pack
U0102-00 - Lost communication with transfer case control module (2F)
( on 08-11-2023 17:04:26 at 122901 mi )
PAM-Parking Aid
U0001-81 - High speed CAN communication bus - Bus signal/message failure - invalid serial data received (2F)
( on 17-03-2026 14:07:11 at 6434743 mi )
PBM-Parking Brake
U0415-00 - Invalid data received from ABS control module (2B)

RLM-Suspension
U0102-00 - Lost communication with transfer case control module (2F)
( on 08-11-2023 17:04:25 at 122901 mi )
TCM-Transmission 8spd
P2159-02 - Vehicle speed sensor B - range/performance - General failure information - general signal failure (2F)

Changed Rear speed sensors as they came up with an error for rear drivers side on another scan
Traced wires as i found a break in 2 other wires and fixed another break.
Still will not clear the code.
Any suggestions welcomed

 

I propose that you need to follow the guidelines in the workshop manual. And not just guess what is the solution.
#1. Confirm electrical source = is your battery good.

This is not a yes/no question. Tell me quantitatively, what is the charge reading of the battery after sitting without running the engine or charging the battery after 12 resting hours.

If your answer consists of a response < 12.6v. Your battery is done. It must be replaced with a fully charged battery.

This is the number one popular reason for the CANN bus communications problems.

 

Thanks for the answer, I replaced the battery and after replacing had the correct levels in voltage but will check again. I also changed the Eco battery as that one also failed. The Alternator is kicking out 14.5V. I will update what i find as i check the battery voltage again.
Would this give problems with the Speed Sensor? The Three Amigos are currently lit and wondered if bad battery levels could cause that issue. The codes will not clear

 

If a module cannot activate or communicate, you will throw codes.
Happy to hear your generator (JLR terminology) is working. And as you recognize, that’s not enough. Its the battery that matters here.
This is not your dad’s old car (or mine) using distributor caps, and a collection of manual or simple electric devices that are capable of running strictly off a good generator... Electronic managed with modules devices require substantial power (voltage and current) to activate and operate correctly.

Incidentally, there is a process I follow with all modern vehicles:
1. Turn all electric components off before shutting down engine.
2. When wishing to start engine
a. DO NOT depress brake pedal and then press and release start button
b. WAIT for all dings and chimes to subside
c. DEPRESS brake, touch and release start button. Engine will start
d. WAIT for a consistent idle BEFORE powering up accessories.
I don’t experience the issues that many others do as I am mitigating the lack of power situation that others find themselves in.

Cheers!

 

The vehicle is at a relatives garage right now and they fixed my coolant leak. They traced the Wire for the speed sensor fixing the breaks. I had previously had a fuel tank communication issue and found two broken wires behind the drivers rear wheel in the large wiring harness. After fixing those they fuel gauge worked no problem. I agree this is not a "normal" vehicle. The fact my relative is unable to find the VSS problem made me wonder if i need to send to the dealer (although i hoped this would not be the case). This is my first LR and only had it one year. Is there a specific manual that is best as i have been trying to find one and having little luck for that year.

 

Well... you have a lot of reading ahead of you ;-)
PM me about the workshop manual. I have no idea why its not a sticky on this forum.

BTW, the reason many have had premature timing chain issues is that they (or the previous owner) subscribed to the idea that its ok to change the oil every 15K.
A one word response: WRONG. I change mine every 5K.
ALL other fluids and filters need to be changed at an appropriate schedule, too.

If its "new to you", I would start by changing it all.

Also, its difficult to support someone if we have no idea which particular vehicle you have. If you adjust your signature in your profile, we don't have to guess. (Though your title makes it clear in this case. I have the same vehicle)

Cheers!
