Codes C0035, C0040, C0055. It's not likely that all 3 speed sensors went bad. I checked the fuses and wiring, and all looks good. I can hear and feel the ABS motor fire at slow speed braking, so I know it's good. I just don't know where else to check.

Yep, it looks like the processor inside the ABS control module has gone out. There is no way all three sensors when out at the same time unless someone cut all of the wires.

C0035: Left Front Wheel Speed Sensor Circuit
C0040: Right Front Wheel Speed Sensor Circuit
C0055: Rear Wheel Speed Sensor Circuit

Here is how to change the ABS module out in the images below and I have included a video to show you how the job is done.

The codes will clear on their own once the repair is made. Check out the images (below). Let us know if you need anything else.

Very informative and thorough explanation. Thank you! However, I did forget to mention that I recently changed tires from p145 75 R16 to p155 75 R16 but these codes were set before with the original tires.

The system may have sent two notifications. If the light was on before the tires were installed then I would replace the ABS control module which should fix it.
