I hooked up my fast tool to car station ..I had no response from device I unplugged all connections to CLC besides the top connector and still had no response from device. I replaced CLC and selector board and still have no response from device. I did power off and reboot each time I unplugged connectors. I hooked up service tool to nearby dmc to make sure service tool is good. Car runs on inspection. What is the TC ? Traveling cable ? This all happened after piston seals where replaced
