The code C1 is a current sensor short or open. Have you looked at test 1,2-0 to see what the current was at the current sensor. I would look to see if the current changes when turning off center. Hopefully this will help decide is you have an open or short. It seems like you have an open. You can look for voltage at the current sensor. It should be approx 1.2v. if so you have a CPU problem. Anything above 2.5v or below.35 check wiring if nothing then a CSD failure.

Fact of the week
Brothers Adolf ("Adi") and Rudolf ("Rudi") Dassler split their shoe company after WWII due to a bitter feud, and established the rival companies of Adidas and Puma. Their personal animosity and business rivalry divided their German hometown Herzogenaurach. The town became known as "the town of bent necks" due to the intense loyalty to each brand.
