You are making a rookie mistake when viewing the CAN waveforms on a scope.
The grounds (arrows 1 and 2) should both be aligned.
CANH will automatically sit on the top, and CANL on the bottom.
Then, and only then will you see if you meet the CANBus voltage requirements for recessive and dominant states. Which include not only min and max voltage values, but the differential values too.
Google CANBus for the valid voltage value range.
Use the automatic measurements correctly too.........Use Ch1 max, Ch1 min, Ch2 max and Ch2 min. Remove any RMS measurements....those are meaningless.
