Bravo T-jet empty battery error messages

[thom81]

Hi,
I forgot the lights on for a few months and when I got back to the car the battery had drained. I revived the battery with a couple of hours of direct 12 volts from a converter and finkshed the charge with a smart charger. The battery was almost new and I'm pretty sure I didn't damage it.
But now I get these errors:
ASR unavailable
ESP, EBD, ABS and hill holder not working
I bought an ELM327 dongle and did a scan with the Android app Torque Pro, but didn't get any error codes out.
What could be wrong? What should I do?
I'm only a hobbyist with car mechanics and electronics, but I'd like to do as much by myself as I can.
Thanks.

I would begin with replacing the battery. The old one may have insufficient efficiency.

Hi, and welcome,
it could be the battery if left "flat" / discharged for many days

worth connecting a ( good) borrowed battery..

does your Bravo have stop/start..?


if so you will need a similar battery.. ( more expensive to buy..!!)

Did you start the engine? If no, then you should start it, and errors should dissapear after minute or two. That is normal error, when the battery is completly dead or when you disconect the main power cables.

Hi, and thanks for your replies.
After charging the battery I had to move the car and drove it for about an hour.
I also tried to hard reset the ECU by disconnecting the battery for an hour after driving. And I've checked the relays and fuses. I'll try connecting another battery next.

As I said, errors should dissapear after car is started. I just cant remember is it needed to turn the steering wheel full left and right couple of times when car is started and stationary. But it cant hurt to do it anyway.
And chek this thread... https://www.fiatforum.com/bravo/283797-esp-asr-hillhold-unavailable.html

No luck yet finding a fix. I haven't tried replacing the battery yet.
I noticed a screech noise from the back brakes. Like the brake pads were about to wear out, but they're new.
Could a stiff caliber be causing this trouble?

I tried with another battery. No luck.

This is the list of the error messages I get:

Hill holder unavailable
ASB unavailable
EBD failure
ESP unavailable

and

ASR is stuck on off

and some light is giving me an error though there's nothing wrong with it.

What next?

I had to take it to a shop and they told me that the ABS unit has an corroded connector and that they have to replace the unit. They told me their shop price for it and that I'd likely get it anywhere cheaper.

Can someone tell me specifics about what and where to buy? How can I best save?

I'll get some pictures of the corroded part later.

Eventually it took only one photo of the ABS-pump to Google for the part. It was easy to find it on Ebay with the serial number. I ended up paying 95€ including postage for a used pump.
The pump is fitted but the problem persists. There's a faulty relay along the ABS-system and the shop doesn't yet know where.
