I have a 32-bit TAC50-04 giving me Local CAN issues. It is reporting Drive Comm Loss and a 1508 Brake failed to echo over CAN fault. Changed the Brake board still the same issue. Measured voltage on LCH & LCL and it was good. Is the resistance also supposed to be 60 ohms for the Local CAN or is it different? Have double checked all the wiring and connections. There is no battery, this is not a Synergy. What else communicates over Local CAN beside the Brake, Drive & CPUA? Would you try the CPUA next to replace? Appreciate any help. Thanks
