Hi all,

i was just wondering if there was a way to reset the service light?
i had my service done at a non fiat garage and the light is still on.

many thanks

If it's the same as the normal 500 you turn the ignition without starting the car, press the accelerator to the floor 3 times within 10 seconds then turn the ignition off.

Then start the car and see if that sorted it

You need MultiECUscan software, a PC laptop and some cables. Search for MES or MultiECUscan for more info, lots of threads on this.

Or, tell us where you are and see if anyone nearby with MES is willing to help.

If you’re anywhere near j4 of the m25 or fancy a journey I’ll be happy to do it for you. I’ve done diagnostics for a few people on the forum.

I'll 'see' your J4 M25, and raise you J13, 14, 15, 16 M4.
(Could even stretch to J17 or J18 at the right times.)

Is it the green cable that's the key one?

I've got the MultiECUscan software and a regular black cable for when my Stilo's EGR was throwing some errors... I remember I couldn't reset my service light but then it was my first go using it and I was more interested in the EGR fault, so didn't spend too much time on it. It'd be good to get rid of the "Service Due" message, if I can do it with the regular black cable.

I think the basic cable will do service reset. If not, MES will tell you when to connect the alternative.

Just the basic ELM / OBDLINK an not adapter cable required:

"Service Interval Reset (334) |INFO|DTC|PRM|ADJ| ELM"

accelerator to the floor 3 times within 10 seconds didn't work for me on 2015 500X 1.4L multiair. Any other suggestions not requiring MultiECU?

I also tried this without success:

And this:
1. In key-on: press accelerator pedal at 100%, remain inthis condition for more than 30 seconds.
2. After this time, always with accelerator pedal downto 100%, press the brake pedal for at least 7 times.
3. Release the pedals.4. Key-off and wait for Power latch

Well even if one finds a method of resetting the Service then you also need to reset the Oil Change. The Oil Change Reset initialises the MultiAir/UniAir system operational parameters. The Multi/Uni Air system learns over time, mileage and oil degradation to adapt for optimum performance.

I've done around 1000km and service light has gone off. I have another 2000km before I'm back home and can connect MultiECU. Bit odd.

I wonder if it's given up warning you, since you're obviously ignoring it.. a bit like the "Shift^" light on the dash.
