Fuel Cut Off Unavailable

So I was driving my fiat and all of a sudden the warning lights on the dash board came on and it was flashing “fuel cut off unavailable” and “stop start unavailable”. The mileage is also flashing..


I have read that my car thinks it has had an accident but I haven’t. I have tried the reset in the manual to no available and have tried disconnecting and reconnecting the battery. Any other ideas?

Thanks

Hello and welcome to the forum.

These are the classic symptoms of the all too common hatch wiring fault.

Check the wiring loom carefully where it enters the rear hatch; you'll need to peel back the rubber grommet to do this, and may have to unwrap some tape from the loom. I'd strongly recommend disconnecting the battery before doing this, but you'll need to unlatch (but not lift) the rear hatch first, or use the manual release. Inspecting the wiring with the battery connected could lead to further damage to critical electronic components.

Odds are you'll find some broken wires and/or damaged insulation.

Report back and tell us what you find, and we'll take it from there.

Could also be a knackered battery. Charge it up overnight and see if it clears.

Hi i have the exact same problem, i have booked it in to a fiat dealer for next Monday is it i have managed to do 15 miles so far is it still okay to drive. As the message says "fuel cut off unavailable" i believe that the switch is unavailable and that fuel actually hasn't been cut off?

Hi, sorry to hear that! I think it is fine to drive but there is no guarantee that the air bag will not go off so use with caution! Mine has now been fixed - it was the airbag control unit which needed replacing. It took the garage almost 2 weeks to find out what it was so maybe worth telling them to check it.

Re: Fuel Cut Off Unavailable

The message means that should you have a crash the fuel cut off won’t engage which is a safety feature which cuts off the fuel supply. This does not affect the driving of the car and won’t set off an airbag.

You can pick up one on eBay for £95.

Re: Fuel Cut Off Unavailable

Dont know if its coincidental or not but earlier in the day my daughters DRL stopped working NSF.

I replaced it but there appeared to be a loose connection on the multiplug or in the connector that clips onto the lamp.

Could it have spiked the CAN or am i overthinking it??

Yes, you’re overthinking. Nothing to do with the Airbag module. You can get good ones on eBay for £95. It will just need a proxy alignment to stop the flashing mileage once fitted. If anyone in here is nearby there are plenty of us that will do it for free. I believe fiat charge over £100.
