Good afternoon,

After 6month standing still I started the Fiat and warning light traction control/ASR did come up. See attachment. Nr 21.What can be the cause? Engine runs fine stationary.

Questions for you.
Was the battery connected during the 6 months?
Did you turn the ignition on and observe the dial prior to starting?
Did the vehicle start promptly?
Any other lights come on after starting or staying on?
Have you let the engine warm up and if so have you switched off and restarted?
What was the outside temperature?
Did the yellow 29 come on?

Ok. My 2008 500 with outside air about freezing runs through ASR and hill start not available among others. After starting nr 29 remains on.

Car drives normally. When the engine oil temp reaches mid point if I turn off and same restart steps all is normal and no warning messages or triangle.

So maybe just an old vehicle left standing in the cold needs a patient turn back to life.

You could disconnect the battery, have a café and restart, making sure you pause between ignition on and start

Regards.

Thanks for swift reply.
Battery was disconnected for 6month. Car started without any problem. Did not mention alarm light before starting. No other lights.engine run for 50min, light still on. Not stopped and restarted. Will start again next week and see what happens and leave a message.Outside temp about 8 degrees Celsius. No nr 29 or other warning.

🌄 Good morning,

Could be that light came on after I moved the car out of garage. But not sure. Car does not have abs as far as I know.

You may have noted I go to bed early, but get up fairly early also, so Good Morning to you also.:)
I may be wrong , but was going by your mention of attachment 21 which appears to show a picture of a skidding wheel?
If it has ABS there will be a metal box under the bonnet with several brake pipes going into it and also a large wiring plug a bit like a car's ECU .
Also behind the brake disc on the suspension there will be a wire going into a sensor near the brake disc on each wheel. Note, not a brake pad wear indicator.
What it shows is if one wheel is turning at a different speed to the other three and reacts to it. If it was just one wheel locked/seized as you moved off and then freed or if one wheel spun as you pulled away, then often after a mile it will reset as normal which is OK.
However if it stays with the warning light on it can be be rust or a damaged rotor or sensor on one wheel causing the reading to the ABS computer bringing the light on. I did have a customer with an Audi A4 which had been standing for several months and when he pulled away the ABS light came on, it was due to rust around the rear brake disc that had given a false reading to the sensor on that wheel which triggered the ABS light. After cleaning it was fine.:)
You can check all the brakes and it may not be obvious, that is why a diagnostic tool is useful as it can show exactly which wheel the fault is at.

I have the feeling that ABS was fitted as standard to the x250 (2006 onwards) models. Certainly the Fiat Training Manual mentions a Bosch 8.0 system, without any suggestion that it was optional.

Anti wheel spin (ASR) and Anti lock brake (ABS) are different. See above 8 and 21 😊.

ASR can be turned off which means more fun or bum clenching 😅. My 500 has a dashboard button as standard.

I would be happy to be corrected, but in my understanding ASR is implemented via an ABS fitted with extra valves for the specific purpose.

As you say.
ASR in a car stands for Anti-Slip Regulation, a traction control system that prevents drive wheels from spinning during acceleration on slippery surfaces like rain, snow, or loose ground, enhancing safety and stability by reducing engine power or applying brakes to slipping wheels. It works with the ABS sensors to detect wheel spin and ensure smooth starts and better grip, reducing tyre wear and improving performance in challenging conditions

It looks like this symbol was phased out at some point in the x250 history, I have its inactive remnants on my dashboard (2013), but it is not in the manual, having apparently been superseded by symbol 28 which also covers hill assist and ESC but not ABS (symbol 8). It might be for a specific subsystem on your model but I have no further clue.

Checking my car. Sitting outside 2c.

OBD connected no faults recorded.

Started ASR not available message. ASR led on.

Let engine temp rise to one below 3 o'clock.

Turned off, wait a tad and restarted. No warning triangle, ASR led off and no faults recorded.

So, for my thoughts nothing wrong with ABS and cold ASR fault is age and temperature.

Goede de morning all who did respond,

While switching contact on, not starting, light was on. After starting light when off. Drove voor about half an hour with no problem. Pushing the ASR button on the dashboard light went on again. So, I think, sensors and ASR system is working fine. And yes indeed the car does have abs. It stupid that after 7 years of ownership still. It not know which alarms, which sensors etc. prefer a simple analogue car. Hope for the best now. Thanks again.

Pressing the asr button turns asr off , when asr off the warning light comes on to tell you asr is off.
