It started with the ESP warning light "ABS and ESP inoperative see Oper. Manual". Then I get those codes that I posted up top and on from there. Before all this though, I got the front right wheel speed sensor implausible code and after looking at live data I could see that sensor was not...

The cost of those batteries are high so I probably won't just buy new ones without charging and testing the less than a year old ones I already have. They were around $500 for both.

The phone error has been there for quite some time. This ESP is new. I will test the batteries and ensure they are fully charged first, then clear the codes, and see what remains. Just looking for other suggestions.

No, I only get a chance to look at this car every week or two and only for a couple hours at a time, if that. Which is why I am trying to maximize my time there when I get it and already have several other avenues to go down if one doesn't pan out.

With having no CAN message from the ESP control unit, what would be the first thing to check at that connector?

In November of 2024 I replaced both the battery under the hood and in the trunk and I called the dealer to get the exact specs of the batteries and ensured that I puchased the appropriate size and type of batteries. I just can't imagine they are bad already?

One thing I did do first thing was check for 60 Ohms on the CAN pins of the N47 connector. I did what the diagnosis information says and unplugged the connector and found that pins 18 and 19 have 120 Ohms instead of 60 Ohms. I don't know if this would have anything to do with low voltage and I...

You may be on track here now that I think about it. I checked the battery voltage in the trunk and it was pretty low, even though it is almost brand new, because the car sits a lot. I never did clear the codes after finding the low voltage. So far I just hooked up a battery charger to it and...

Thank you so much for the suggestions. With Starfinder I pulled the wiring diagram and diagnosis info for the N47-5 ESP module here:

Where would you start with this report?
