Yes it could be that too if there's any water ingress or moisture on the connectors.
Looking at your fault codes you do have an injector fault. Very often such faults can cause a cascade throughout the other control modules as they all depend on data from the ECM.
This might be one reason why you have the other "U" code faults. Of course the injector fault might not be directly affecting the other modules, and it is a comms issue due to water ingress that's causing these instead.
TCM is a good place to start, but I'd be looking at that injector too especially if you have "live values" available on your diagnostics. yµ (idµ - eAµ) ψ=mψ

The tray under the TCM was full of water, and the connector that sits in the tray was totally submerged in water, all cleaned with electrical cleaner, dried and WD40’d, just been for a drive both solo and with the trailer……… and so far no faults (apart from coolant level ) now where’s that parts catalogue

Well done
You need to prevent further water ingress so make certain the bonnet seal and the scuttle cover are correctly seated!yµ (idµ - eAµ) ψ=mψ

ive just changed a rear stop and tail bulb and it’s gone back into effing system failure !!!!!!!!!!!!!!!!! 😡😡😡😡😡😡😡😡
Is it possible you've forced the new bulb in the wrong way? I know they're keyed but I've seen it done..

Starting point would be to remove the offside rear light assembly and dry it out thoroughly as it is possibly still shorted at the reverse lamp. Could also try it with the assembly removed and see if there is still a problem. Maybe other side has water in it as well.

Nearside light cluster bone dry, had off side cluster off, dried with hot air gum, cleaned all wires and connectors with electrical cleaner, WD’d it all and 20+ reverses later and system failure !!

Not as many codes,
Injector 1
And a few communication codes
The TCM was quite bad, don’t know whether to bit the bullet and get a new TCM, probably won’t be able to code it with my iCarsoft !!

No further on unfortunately !!!!!
Morning all, I’ve posted recently about the little problem I’ve been having since buying a disco 3 from an auction, it was described as having a severe mis-fire, it would appear that the misfire is as a result of a totally different problem ie…… caused through a possible wiring fault of some description !, this only manifests it’s self in reverse and only if you accelerate in reverse and not let it move under its own steam, which I could live with except with the caravan hitched up I’d have to give it a bit of gas at some point.
Has anyone had a loom issue with reverse or even a broken wire ?, because there seems to be a cracking sound ( like a spark plug firing when placed on the engine to see if it’s sparking) coming from the offside bank in the engine bay ( don’t ask how we know !!!!!!)
CheersIf i fell into a barrel of tits......i'd come out sucking my thumb
if in doubt.. flat out
