    Intermittent psychedelic dash experience + runs rough + other random issues

    2014 Fiat 500 Pop, auto, 73k miles.

    I inherited this car in a divorce; she was my ex-husband's. That not withstanding, I've attempted to give her the love and care that any abandoned vehicle (and car loan) deserves. She's had her slew of abuse at others' hands, so I try to be gentle with her.

    Anyway, story of my life aside, here's the timeline of what the car has been doing. I love a disco party as much as the next gal, but there's something about it happening when you're on your way to work that just sucks the fun out of it completely.


    Late Nov 2019: it's a 50F day, sunny, and I'm on my last errand. I go to start her, and the dash lights up like a psychedelic christmas tree, and the engine is -- wheezing? It's like she's revving yet the tac isn't moving. I am getting transmission errors and engine errors, so I shut it off immediately. Two restarts later, she's drivable but running rough. She threw code P0659 "Accuator supply voltage circuit high", which went away after having it read at the autoparts store.

    After several days, I am lulled into a sense of false security as she seems to be running okay again.


    Dec 2019: she did it again, 20F day, and snowing heavily. Process is exactly the same as before, except that before I can get the code read again, she's already cleared it.

    I am again puzzled by her behavior, but she begins behaving again.


    Feb 2020: ... aaaaand she does it again. Threw code P0659 again. This time, add in that now my back hatch won't open with the fob (so, you know, AT ALL). Still hasn't righted itself.

    A few days later:
    snowing again, 20F outside. This time, I get the dash warning light with the red thunderbolt -- you know, the one for the electronic throttle control? The car isn't running any rougher than usual, though. Her check engine light stays on, as does the red thunderbolt, but only a couple of restarts. I didn't even get a chance to get the code read before it cleared. She's been just chilling out since then.

    Where's she at now?
    - still no rear hatch, but the front doors are responsive to both fobs
    - seems to be running smoothly again
    - no check engine light
    - no red thunderbolt
    - no disco dash party

    Things I know:
    - battery tested "fine" recently (battery was replaced at 35k miles in 2017)
    - had the oil changed last month, and everything superficially was A-OK according to those dudes
    - I did the spark plugs last at 53k miles (did them myself); no issues then
    - car appears to be in good mechanical condition otherwise (no oil leak or loss, runs okay other than these times I've described, although sometimes I get this fun "ticking" sound that is new -- not knocking, not coming from the compressor, just a tick-tick-tick I can hear inside the cabin)
    - she seemed to be having a low power/shifting hard issue, but since I upped her octanes (see below), this seems resolved

    Things I plan to do:
    - tonight, I'm going to try a reset of the system (pull battery, do the reset sequence); hoping this fixes the back hatch as that's crazy annoying
    - change the spark plugs in a couple weeks
    - maybe try to clean the battery connection?
    - we're rapidly at the limit of what I'm capabale of doing on my own without a lighted garage but suggestions are welcome

    Things I wonder:
    - I have been running only 91 or 93 octane since this started on the off-chance that it's somehow tied to the quality of the fuel. I just moved to Iowa where they put 10% ethanol in the low and mid grade fuels, so I switched after the first incident just in case she was intolerant of the EtOH. Could bad gas cause a misfire? If so, why does she keep misfiring?

    I would love ideas. I have videos and pictures but I don't know how to post them. I'm not completely helpless when it comes to cars, but I'm broke, friendless, and really need this car to work. As of this second, I don't feel I'm about to get stranded -- but I am a realist and understand that could change at any moment. Like today.

    I am sorry your car is having problems. Here's the little I found and where I'd start... not a lot to go on.

    The official code listing is comment #48, at http://www.fiat500usaforum.com/showt...ighlight=P0659

    Reading a bit further (other sites), this can be a short in the wiring. Since the hatch stopped working, I'd look at the hatch wiring harness. The wiring harness is at the left side near the hatch hinge. It is possible the harness plug popped out of the hatch or body and a wire has been cut by the sharp edges, shorting out. Try unlocking both front doors. If the hatch still won't unlatch, there are ways to manually pop the hatch. (The harness fail is common to models earlier than yours, but no reason it couldn't happen on any Fiat.)

    For posting pictures, you can use the "Insert Image" icon, then upload from your computer.

    I'm hoping our experts know more about this problem.

    It’s as simple as this.... You need a new car battery. The dash board will light up like crazy. You can’t lock the doors, or open the rear hatch. The immobilizer will kick in. The car will run really rough. May not even start. If it’s a automatic transmission, you might no be able to take the shifter, out of park. Check the voltage on you battery with a volt meter. Should be 12.4 volts or more. With the engine not running.

    This happen to me my last day at work. Years ago. Fiat provided a tow to the dealership, for a free new battery.

    Sorry you're having issues. Here's the P0659 code definition from a previous post. First step when you are having issues is to make sure you have a stable charging system. The only way to check this is to have it tested. Be wary of having your car tested at a retail parts store as many of those folks don't have any training or diagnostic skills. They'll run a simple test, but really aren't paid to be technicians and do in-depth diagnoses,

    You need to have hard numbers as "fine' is a subjective term. The battery needs to be load tested and so does the charging system. Note, sometimes the person running the load test on the battery will do it once and proclaim it "fine" but have them do it again and take note of the measurement. The battery may be OK for that first test, but then could fail on the second test. The battery would need to be charged up and then tested or replaced if it fails after a full charge. Many parts stores will charge the battery for free.

    As you can see in the post below, connections and grounds, in particular, could be an issue. Battery connections need to be clean and tight including ground connections. Cleaning connections, testing and charging the battery are things that aren't too difficult to do and may fix your issue. Even if it doesn't, you will be in a good position for further diagnosing as you can't go further without actually knowing that the battery and the charging system is working the properly.

    The Powertrain Control Module (PCM) detects that the internal actuator supply voltage is high for 0.05 seconds.


    Default Actions:
    ETC light will flash.
    MIL light will illuminate.




    Possible Causes:
    PCM POWERS AND GROUNDS
    POWERTRAIN CONTROL MODULE (PCM)


    NOTE:
    Diagnose and repair any charging system or battery voltage DTCs before continuing with this procedure.
    The link below goes to an article that shows me removing the battery tray to get to the ground connections. Note, it is on an Abarth model, but should be similar to the Pop.

    Good luck and let us know how you make out.

    Thanks for all the helpful info, everyone.

    As of this moment, I've replaced the battery. Waiting to see if that fixes it. I have since learned that the engine "hunting" issue is a long-standing issue of this car. My ex (who had the car while I was out of town on business traveling frequently) apparently had it seen back when it was under warranty. They never did anything other than a reset.

    It's also unclear as to whether the battery was actually replaced at 35k. The same ex told me they did but records say otherwise. So, maybe it was just a super old battery? We'll see. I'll update after a while

    Just to put your mind at ease, one of my Fiats gets over to Iowa City now and then and I buy gas there and in Wisconsin and Illinois. Your 500 is engineered to take any kind of gas sold in Iowa. Ethanol (10 percent and 15 percent) is not a concern unless you are storing the car over long periods, say for more than 6 months. I've run and stored my three Fiats with E15 over the winter with no problems, but ethanol blends deteriorate more in storage than non-ethanol fuels so if Im putting some thing into storage I generally prefer non-ethanol fuel.

    Sorry you're having problems. I have nothing to add other than my back hatch also has lately and only on occasion refused to open for me. So keeping an eye on this thread...

    if you are having hatch lock/unlock problems, probably 90 percent of the time you will have broken wires back there. You will need one of these:

    https://rover.ebay.com/rover/0/0/0?m...2F143426884953

    If you've worked with a wire terminal crimping pliers then you won't have any problem with this job. I used one of these a few years ago on one of my Fiats and on the second Fiat I decided to buy some wire and make my own. The kit is much easier. If you make your own, as I did, you can't use standard auto wire, you need to use wire with more copper strands for better flexibility. The bigger issue is ordering all the different sizes you need and you'll usually find only American Wire Gauge (AWG) sizing so it gets very tricky to order exactly what you need. You can't undersize any of the wires or they could melt under load and the fuse for the overloaded circuit would not blow. The kit I linked to above uses that special wire and has all the correct (Metric, not AWG) sizes. All you need is a halfway decent crimping pliers, maybe $10-20. Or buy the harness on eBay and take it to any shop for installation. They shouldn't charge more than 1-2 hours labor. I think I did mine in under an hour.

    YES! I checked yesterday. You are so right; this is the issue. It all looks very sketchy in there:

    IMG_5333.jpg

    there 3 if not 4 more wires that I can see that are ready to fail...

    After spending close to 1K on the wheel bearings and with everything else going on right now, I'm tempted to try this myself. From everything I read and watched online, it's a matter of unplugging the battery, removing the trunk door panel, halfway decent crimping pliers, electrical tape, and patience.

    I've got lotsa time...
