I have owned a 2017 F-Pace 35T for 3 years without any issues. I decided to list it for sale and Voila! The entire dashboard lit up.
The traction control light is permanently on and the car keeps cycling through the following messages: APSC not available, Stability Control not available, Emergency brake assist not available.

A search of the forums suggested the battery may be the issue as the car heavily relies on the battery. Replaced my battery which was the original but the warnings remained.

I had a local shop use their scan tool (Snap On Solus Legend) and it came back with code C1A96-64 - Brake Lamp Switch Circuit - Signal Plausibility Failure. Shop suggested Brake Lamp switch... cheap enough I picked one up for Jaguar and replaced it and cleared the codes. 30 minutes later the faults returned.

I went back and rescanned at the shop and now the car shows 2 codes: C1A96-64 - Brake Lamp Switch Circuit and a U0001-81 - High Speed CAN communication Bus.

The forums have attributed these warning lights to either a weak battery OR an ABS wheel speed sensor. Before I throw more money at parts or take it to Jaguar for an expensive diagnostic. I'm seeking advice on how to proceed and what these codes generally end up being when scanned.

I'd like to fix the fault before selling. Appreciate all insight.

 

Unplug the wheel speed sensors one at a time and see what codes it triggers as each one is disconnected. I would suggest investing in cheap ODBII dongle and Torque pro or similar so you can read the codes instead of going someplace.
Also if you don't want to do that go to Autozone or similar and have them run their scan tool. Might show different results.
