Technical Lights on dashboard

[berlinasportiva]

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?

I’ll dig it out a bit. Good chance in ABS sensor. TPMs is based on wheel rotating speeds in Tipo. Good reader should tell you what’s what. Were are you based?

Hi, thank you for the he reply, It was the abs sensor as you thought. I had it repaired in April. I am based in hertfordshire

I have emailed them with my vin number so hopefully they will let me know

They said it is the ABS wheel sensor.

 

[julia11]

Had it checked, so the correct part was ordered. The man used a top don reader, it was saying tpms needs recalibration. He done that, light off for now.

 

[berlinasportiva]

Yes it requires recalibration after any component is changed

I spoke too soon. Just been out, 4 days and it is back

Damn, do you have MES?

No, he said he would take it to his garage to do it there. Probably easier to have mes. I did have a read about it. Worried I would brick my car

 

[julia11]

No luck.
No codes showing. Tyres done to bar not psi. Cleared, updated and reset.
Emailed a fiat specialist in Stevenage, who don't have the machine

I’m driving from Leeds to Swansea on the 8th, maybe we can catch up along the way? I’ll have MES on me

Thank you for the offer. I work in a school so am not about much

Brilliant. Thank you

I recalibrated it, it went away. I drove for a few days and it's back. Any ideas please?
I found some info through Fiat confirming my car does not have the sensors in the tyres.

Strangely..,

That error code can be related to the "Electric Handbrake"... Could this apply in your vehicle?

That’s an error with wheel speed. Can you connect to abs and show is live readings from all 4 wheels?

as far I I know hillholder is operated by abs pump so maybe that?

I have an old style handbrake

I will run it again when it is light and show the results

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

The abs wheel sensors can cause the ABS warning but not usually all the other lights. A simple charging check would be a good idea. A volt meter on the battery should show 14.4v at tickover if the charging is OK. It could be a charging problem or a poor main earth. Abs wheels sensors can become disorganised. A fault code reset might just cure it. If you can identify which wheel sensor it is it would be worth replacing the one causing the fault as they should not be too expensive. It may even respond to being disconnected and reconnected. Some cars the wheels senor will reset its self of any 'fault' goes away but my Bravo did need this fault cleared by MES software. I hope you have the cause correctly identified. (PS I dont like all these sensors playing up. Give me an old car and a spanner any day)
