If the tyre-pressure warning has come on in your Abarth 124 Spider (2016–2020) after you’ve adjusted the pressures or changed a wheel, you reset it with the dashboard TPMS button and a short drive. This is a routine step, not a sign that anything is broken — the system simply needs to be told that the current pressures are the ones it should treat as correct.
How the System Works on the 124 Spider
The 124 Spider uses a monitoring system that watches for a tyre that has lost pressure and lights a warning on the instrument cluster. Because it works from a stored reference rather than reading an exact PSI figure for you, it needs to be re-taught whenever the correct pressures change — after topping up, after a seasonal wheel swap, or after a puncture repair. Until you store the new baseline, the light will keep reminding you that the readings no longer match what it last recorded.
When to Reset
- After checking or adjusting the tyre pressures.
- After changing one or more wheels or tyres.
Getting Ready
- Check pressures when the tyres are cold — after the car has stood a few hours or been driven less than about a mile. Warm tyres read high and will throw the baseline off.
- Set all four to the figure on the driver’s door-pillar label (a loaded/high-speed figure may also be listed).
- Don’t forget the spare if your car has a monitored one.
- Have the engine running for the reset so the button and cluster respond.
Resetting the System
- Set all four tyres to the correct cold pressures, then start the engine.
- Press and hold the TPMS ‘SET’ reset button until the TPMS warning light flashes and an audible signal sounds.
- Release the button — the procedure is registered.
- Drive for about 15 minutes above 25 km/h (15 mph) so the system calibrates.
If the Warning Stays On
- Recheck every tyre — one corner a few PSI low is enough to keep the warning lit, and it’s easy to miss by eye.
- Confirm the set procedure — the light should flash and beep when you hold the button; if it doesn’t, the reset didn’t register.
- Complete the calibration drive — a couple of short hops may not add up to enough continuous running.
- Cold mornings can pull pressures below the threshold overnight; top up and re-store rather than assuming a fault.
- After a wheel swap, the baseline moves with the new wheels — always re-store once they’re fitted and set.
- A slow puncture will keep dropping one corner; if the same tyre falls again after a day or two, have it inspected.
- Still showing with correct pressures? A sensor may have a flat battery — look up the code on autodtcs.com.
What Happens Next
Once the reset registers and you complete the calibration drive, the warning should go out and stay out for the trip. If it clears and then returns after a cold night, that’s normal pressure loss from the temperature drop — re-inflate to the label figure and store again. A light that returns quickly on a warm day points to a genuine leak rather than a calibration issue.
Frequently Asked Questions
How do I reset the tyre pressure light on an Abarth 124 Spider?
Set the pressures, then hold the TPMS set button until it flashes and beeps, and drive 15 minutes above 25 km/h.
Where is the TPMS button?
It’s the dedicated SET button for the tyre-pressure system, near the steering column/dash controls. Hold it with the ignition on until the warning light flashes and the beep confirms the reset has started. If nothing happens, check the ignition is fully on and that you’re holding the right control.
Do I need a tool?
No for a normal reset — the button and a short drive are all it takes. A workshop tool is only needed if a pressure sensor itself is replaced, since the system then has to learn the new sensor’s identity. Everyday resets after inflating or swapping wheels are a driver job.
How long is the calibration drive?
About 15 minutes at over 25 km/h after pressing the set button. Steady driving works better than stop-start town crawling, so a stretch of open road lets the system settle and confirm the corrected pressures more reliably.
Why did the light come on when nothing feels wrong?
The car compares current readings against its stored reference, so even a small, even drop across all four tyres over weeks can trip it. Cold weather is the most common trigger. Check and correct the pressures cold, then re-store the baseline — it usually clears without any repair.
Do I have to reset it if I only topped up one tyre?
Yes — set all four correctly first, then run the reset. The system works from the whole set as a baseline, so adjusting a single corner and storing that as the new reference keeps everything consistent and stops a false warning later.
If the warning came on with other lights, decode the code on autodtcs.com.
