Car Fault 1525
CAN channel 2 did not receive a message for 60 seconds.
When I run a DCN command is shows no data received from the CN0: CNA_COP1 board or the CN:1 CONTRLR1 board. Then when I run a TECCV it displays that all the ports on CN0 and CN1 failed to respond. I have no communication from the CAN board in the controller to the CAN board in the COP. I verified power on both these boards and reset them. Tried a TECC command to re-teach and verify but no luck. They are just flat out not talking to each other. The prints are only getting me so far, unfortunately I do not have a TAC50 controller Manuel, learning how this thing communicates on the fly.
How can I locate what is causing this? And or how can I determine if one of these boards is bad?
Any help would very much be appreciated, thank you.
