    Question CEL Hill Holder ESC Error Message

    2015 Fiat 500c 1957 Edition

    Happened last night, out of the blue... all these lights came on. It was raining hard yesterday so not sure if it is related to wire fault, sensor, or what... But wife's tells me that the check engine in the car turned on. When I get home that night and turn on the car to check, and a lot more than just the Check Light Engine came on:

    ESC
    Hill Holder Function Disabled (or something to that end)
    Check Engine Light with a message in the display of Service Engine

    I was not able to capture them as by the time I went back in to grab the phone to take a video and a few photos, the ESC and Hill Holder message would no longer appear...

    And check engine light went out not too long after that...

    I did search on the forum and found several threads but none of the threads had closure... meaning, nobody came back reporting what solved the issue and what got documented in the service documents from the dealer.

    I have a code reader for my BMW but nothing for the FIAT... will buy one today (I know these can be read at the local autozone for free, but I have been meaning to add an inexpensive OBD II reader for awhile now). And the OBD II apps that I downloaded last night, I could not make them work with the Carly OBD adapter (which works great in my BMW). Not wasting $ buying any apps if for a lot less I can buy a reader...

    Anyone that has gone through something similar? Can you share details on codes read, service write up on the fix? Parts replaced?

    I will need to schedule an appointment with the dealer to take it in... but getting on a plane and will not be able to do anything for a week... it is my wife's car and not sure if I should park the car while I am out and have her use mine...

    This was the only photos that I could take... shows the CEL only...

    Common problem. One of your wheel speed sensors has failed. The Fiat shop can use their special tool to read which one, or you can do as I did, just replace all four. If the car is still under warranty, they should find the bad one and replace it. No biggie and not hard to replace.

    I think I have this problem (Service ESC, Service Hill Holder, ETC indicator, with CEL that stays on). If it's a wheel speed sensor, what are the odds of my studio not covering it under my warranty due to the mods I have (Unichip, Neu-F rear torsion bar, El Gato front chassis braces, V2.1 air induction system)???

    I think it depends greatly on the attitude of the dealer. If they plug in to read the codes and find some unusual things, like the identification of a Unichip, they could just unplug their scanner and consider it a voided warranty. Or, they could scan and find the bad wheel sensor and replace it.

    Another thing that takes out the wheel speed sensor are failed wheel bearings. Same thing holds true I suppose: They could see the chassis brace and aftermarket goodies and claim premature wheel bearing failure because you beat on the car, voiding the warranty.

    Guess the only way to find out is roll the dice and take the car in.

    Problem is this doesn't seem to set a permanent code when this happens. For most folks it's temporary - it shows up maybe once every 3 or 4 months. In that case, unless it happens to occur while in the dealer's possession, then they will not be able to diagnose it. So the odds of getting it fixed by the dealer are very slim unless your code is sticking around.

    Why do manufacturers make cars that don't keep codes around longer? Because OBD systems are mandated for emissions and safety purposes. Once the problem is gone, there is no emissions or safety issue, so they just dump the codes pretty quickly. Why? Because then they don't have to fix what's wrong, of course. If it kept the codes around longer, they could detect a part that is on its way to failing but hasn't failed completely - and they would have to repair a lot more cars. Best just to erase the codes as soon as the problem goes away on its own, and the dealer shrugs its shoulders and says there's nothing to fix.

    I had all those lights come on mine and it was the body control module after diagnosis at the dealer

    Every so often was my experience until the last couple of weeks and now it seems to happen every other day... I also have noticed a slight "click" in my steering when I move the wheel left and right. Not sure if this has something to do with it. I have taken the Unichip off and will be taking it into the studio, however right now no CEL...

    Was there a CEL when you went in?
