CAN BUS waveform

Post by Bazgreener »

hi all,
my first use of the picoscope on a 2005 Caddy van with multiple CANBUS communication issues.
I have a constant 2.5v so would i be correct in thinking that there is a short between CAN H & CAN L? Resistance is 60ohms across the H&L so this would indicate resistors are ok?
Next step to start disconnecting modules and see if waveform corrects and if not then i have a wiring issues somewhere?

thanks in advance
Barrie
