Service Suspension System
 

I am getting the codes
RSS:
C0640 current
C0635 current
C0710 current

these codes are all occuring after recently replacing the EBTCM. Replacing the EBTCM got rid of the previous ABS codes that I had and replacing the CVRTD fuse got rid of "speed limited to 90", however now the RSS codes appeared. what could be a possible solution to this problem. Ive seen some posts speak of the steering wheel speed sensor or the ignition switch. any input would be greatly appreciated. I also have a replacement CVRSS module but that seems to not affect any of the current codes.

what were the original codes
it almost sounds like the sensor at the bottom of the steering column
here r a list of code meanings
