ESP DTC 5026 and 6001 on LAUNCH Tool no Lights
Hello all,
US here (gas, miles, feet, lol) New to this forum with a fairly new to me 2011 ML350 4matic (not Bluetec / Diesel still learning all the differences) with about 200k miles on it. We got hit with a cold blast this past week down into the 20s-teens overnight (F), and was our first time having this SUV in cold weather, eventually realized how low the battery was after a few hard / rough starts that threw the check engine light (no lights prior to cold snap). Changed the battery (don't get me started on that), pulled out the scan tool to clear the light, I have an Amazon Launch tool w/ the MB option that lets me read / clear DTCs, after the battery change and noticed I have 2 DTCs that persist under the ESP section of the tool, a 5026 and a 6001 (descriptions given on the tool below). The ESP light is not lit up on the dash, the button on the center console appears to work fine when I push it, and car drives fine as far as I can tell regarding the ESP system. I would imagine if the system wasn't communicating with the ESP control unit I would get a light of some sort.
I don't know how long this has been active as my wife drives the car daily, and I don't check it other than service periods or if she complains about something. Is it possible that my cheapish Amazon tool isn't reading the code properly? I think I got it based on a recommendation from someone off this or another MB forum. I tried looking it up and perhaps it related to the wheel speed sensors? I did do all around brake job a few months ago, is it likely that I just messed up one of the sensors during the brake job? Any way to check which one it was or verify?
ESP DTC
5026 - No CAN Message Was Received from Control Unit
6001 - The Supply Voltage of the Control Unit Is to Low
Any thoughts appreciated.
Thanks,

Thanks,
I came across this short video that showed 6001 is to do with a burnt fuse. See it for yourself. May help you. Here's the link. Good luck.
