Still having LCH/LCL Issues with this car. Just replaced CPUA with brand new board and have swapped out brake board. Local CAN is reading about 45 ohms. Would the drive board possibly be causing this even though the Brake Board is also reporting Comm loss? Thought for sure it was CPUA. Is the LCH/LCL voltage supposed to be about 2.5/2.4 VDC like the other CAN channels? Any chance the IOC can cause this? Jumpers all check good on IOC and CPUA.

Also car will run for 10 - 20 minutes before faulting out with CAN CH 1 faults. Faults are 701, 1507, 1508 & 1515.

Appreciate any insight on this. Customer is getting upset.
