2015 LR4 - Mice, Maine Winter and ABS Issues Galore!
Working a handful of issues on a 2015 LR4 and hitting a bit of a wall.
Interested in some POVs from the group here on what may be next best course of action.
Batteries have been replaced (using GAP IID tool interface), parking brake was "stuck", released with manual cable, now functions as should.
My brain is taking me down a path to evaluated the wiring (possible mouse chews over the winter while in storage here in Maine, lots of poo and urine in the lower cavity of the main battery box).
Plan to check power to ABS module with test probe and establish clear / clean grounds for ABS module in wheel arch etc... where else would you start?

It looks like a battery issue to me even though you have replaced it with a new one. Check carefully all the
battery connections and clear all the faults via GAP.
Most of the faults listed are likely a cascade/historical, run the car and see what faults comes back.yµ (idµ - eAµ) ψ=mψ

All are locked down tight. Still won't clear. Thinking we should investigate the grounding posts for the ABM module under the wheel arch covers...

What is the cold, resting voltage reading from the battery? For example, if it reads 12.4v as opposed to 12.6v, the battery contains less than 50% of designed capacity.2015 LR4 HSE Lux Aintree Green

With the battery voltage at or above 12,6v (but no lower) turn ign on and don't start the engine. Connect to GAP then read and clear the stored codes. If they will not clear check the battery connection to the BJB is tight.
If still the codes will not clear connect a battery charger for 30 min then try the same procedure above.
If that doesn't improve the situation then it may be time to look at the wiring/plug connectors to the TCM in the ECU box behind the battery.yµ (idµ - eAµ) ψ=mψ
