We have an IMS computer on site but it it stopped communicating at the same time as the shutdown. It will communicate with the other 2 cars no issue. CPU board light is on solid green DSP indication light also on solid green. No blinking. Any suggestions? Things to check? Last edited by GatorSK1N; 02/17/24 12:19 AM.
