    Check Stop Lights Message on Panel.

    Condition: The subject message appears at start time, turns off, and the stop light icon (bar with two lights hanging down) remains.

    All three stop lights do not light up when brake is applied. Checked right brake lamp off the car and that works. Assumed at this point that problem is probably not the bulbs (all three are not lighting).

    Checked the only two fuses that mention "stop light", F37 (Stop light switch, Instrument panel node) and F51 (Stop light, radio sw, climate control, clutch, rev gear, parking sensor, rear cam, sunroof) and they are not blown.

    Need help and advice at this point. There must be a brake switch somewhere? Hydraulic or mechanical? Somewhere near master cylinder? Pedal?

    Thanks in advance,
    Bob

    Bob, it's a mechanical switch down at the pedal cluster under the dash. Just replaced one on my non-L 500 Sport. $2.33 at RockAuto for an original Mopar switch, about $9 at my great local dealer and in stock.

    Mine started to act up in cold weather and I think it was the contact grease getting thick and dirty. I did an autopsy of the old one. There are two sets of contacts - one for the brake lights and I think the other manages cruise control cutout and Electronic Stability Control. My brake lights were working fine but my stability control (ESC) warning lamp was coming on and my AlfaOBD scan software pointed me to the brake pedal switch.

    Anyway, no tools required - it just twists out. There are some instructions here on the regular 500 forum posted by the site administrator. The switch is self adjusting so you need to be sure that you are not pressing the brake pedal while you are twisting the new switch into place.

    Hope this helps!

    Paul

    Thanks Paul. Have not had a chance to work on it some more, but am intrigued by your symptoms and the pinpointing of the brake switch by Alfaobd.

    Adding to my symptoms after reading yours,
    1) ESC seems to kick in if I brake while negotiating a sharp curve (I now think that the outside wheel is pulse braked as it would be rolling more than the inside wheel, all without a "brake applied" signal from the switch).
    2) Last time I did the same maneuver, I got the ESC and Hill Holding unavailable warning messages non stop. I had to restart to clear the messages.

    Anyway, back to the "Check Stop Lights" warning message (happens everytime on startup), I do not get any detected trouble codes (DTC) on my OBD adapter (OBD MX) using Alfaobd Demo or the OBDLINK app that came with the adapter. May I ask the specifics on how your Alfaobd pointed to the brake switch? Was it a DTC? Did you have to go to the BCM (Body Computer) section?

    It would be nice to get a definitive brake switch OBD diagnosis instead of my futzing around the problem.

    Thanks Paul,
    Bob

    Bobby, yes, I also received The Hill holder message, and yes, it required a restart to clear but after some time (probably less than 25 brake pedal applications) of city driving the messages would return.

    I wish I had some screen shots from my AlfaOBD (full version) but I seem to remember that the code was in the BCM as intermittent. I also use VCDS on my VWs so I could be confusing the terminology a bit as I've been using VCDS/VAGCOM for almost 20 years and I'm new to AlfaOBD.

    I remember thinking (before I checked with AlfaOBD) that probably one of my ABS sensors/rings was bad or rusty because I figured that would affect stability control. Also, keep in mind that while I own a 2014 500L, this troubleshooting occurred on my 2012 500 Sport. I did check the parts photos online and it appears that the L and the regular 500 use the same pedal cluster brake light switches. And I've driven hundreds of miles now with the new switch and no more ESC/Hill holder unavailable messages.

    I'll be curious to see if you trace it to the pedal switch.

    Paul
