While in gear, the car shakes and the traction control warning light (red triangle with exclamation point) comes on. Shaking is during braking and acceleration. The shaking stops when traction control is manually disengaged. Most recent incident, the warning light and the ABS light illuminated and shaking came back. What is the correlation (shaking/T/C and ABS) and how is it repaired?

The shaking while acceleration related to traction control would be the computer retarding the time because it thinks it has wheel slip. Are all your tires the exact same size?Your going to need to have a full scan of all the computers and write down all the exact code number's not code descriptions. You cant use a diyer scan tool or free code read at the auto parts store. Those scan tools cant read all the computers you might even need that scan tool to diagnose the problem. There is no cookie cutter answer even if I was there with your car the first thing I would do is a full computer scan.

I'm getting 3 codes: C0035, C0045 and C0236. After reading the codes and driving, the 0035 has gone off.

The co236 is for no engine rpm readings to the abs computer. The first thing the want you to do is look at the abs live data and let the engine idle and see if there a rpm reading. If no then go to the engine live data and see if there is a rpm reading at idle. The c0045 is for one of the wheel speed sensor circuit failures it says to inspect the wires and sensors to start.I would watch the wheel speed sensor speeds while moving in the abs live data and see if any read off the rest. Like I said before you might need a scan tool to diagnose the problem.
