Technical Lights on dashboard

[julia11]

2 days ago while driving home, low tyre pressure flashed up, then abs unavailable, hill stop unavailable, esc unavailable, low pressure unavailable.
When I got home I checked with OBD2 reader it is showing no fault codes.
It shows - abs unavailable, hill stop unavailable, esc unavailable, low tyre pressure unavailable when ever I start the car.
Does anybody have any ideas please?

Is your OBD engine only..? P codes

Likely codes are BODY : B, C and U

Generally those codes could be triggered by one faulty item..

Brake / clutch switches..

Is your tyre monitoring read via ABS /wheel speed?

I see you have posted about Dash Cam and other Electrical loads,

Maybe its a CANBUS thing? , depending how you have powered and "Additions"

I hadn't got round to hard wiring luckily, I just use cigar lighter to power it when I drive

It could be that the battery needs replacing, especially if it's more than 5 years old. The battery on my 2018 Tipo was replaced under warranty at just under 2 years old & has been fine since, but low battery voltage can trigger all sorts of warnings on the dashboard, effectively because the cars computer can't check all the different systems because there's insufficient battery power.

I had the battery replaced a couple of months ago by the AA, but it could have broken

Hmm, it could be a faulty or not powerful enough battery - the diesels take a lot of power to get going. Otherwise I'd be looking at things associated with the battery, like connections, the earth strap (they can come loose or begin to corrode on other Italian cars) & the alternator. It won't be all those warning areas that are faulty at the same time, in case that's stating the obvious. My money's on battery/charging circuit - seems very curious that the car's begun showing errors shortly after a replacement battery.

Thank you

You need to connect to the ABS unit and do normal diagnostics. I think..

My Bravo did this then the battery failed gterminally a few days later. Try another battery if you can and see if it makes a difference. Or charge your and see if it changes.

Update - checked using a garage obd reader and it is showing a wheel sensor, so
