Were you working on the brakes or tires/wheels? No
Were you exploring control modules with an OBD device? No, chassis control error occurred on dash unexpectedly and then I pulled error code with an OBD code reader.
Did you hit a curb or big pothole? No, don't think so.
Original or replacement battery? Original LI battery was replaced 3 years ago.
Take a look under the car and search for the wheel acceleration sensor. It is likely on the knuckle or lower control arm. Maybe it came loose or the cab is cut/chafed?
Have you tried clearing the code to see if it returns?
Digging around it seems there is a body acceleration sensor, inside the engine bay on the shock towers/wheel house. Not sure if the wheel acceleration sensor and body acceleration sensors are the same or not.
A PASM diagram showing the sensors and actuators would help but I don’t have one.
My cars have had lots of issues with rodent damage over the last few years. I will take the wheel off tomorrow and inspect for any obvious damage.
I tried but was unable to clear the code. The PASM controls on the center console are inactive now and I assume ABS is not working since I think the speed sensor is also an ABS sensor.
I'll make a best effort to fix it myself before taking to a shop.
The circled wires in harness under the hood near right firewall were damaged, see post-repair photo below. I didn’t take before-repair photos but several wires were broken and/or chewed.
I didn’t ask my indie shop about the exact details of the repair but error light is off and car is good now 😁.
