[QUOTE="clevor, post: 25129, member: 6998"] After seeing all of these communication errors, I researched this and eventually found that I have a class 2 serial data buss that needs to be checked for proper operation. As I said previously, disconnection the clear connector from the tcm clears all of these codes. I now only have a U1000 that says some component is missing from the class 2 serial data buss. Which is the tcm. So, I have some diagnostic equipment coming tomorrow that I hope will help me further confirm the tcm is bad or point me in a different direction. [/QUOTE]
