CANBUS problem - no data received - led not blink

Hello,
I’m interfacing to a one canbus of my car running at 125kBaud and am just using the sample read program with the speed changed to 125.
I’m not getting data and the red led (rx) blink very slightly; you can only see in the dark…

On the other bus that work to 500K (diagnostic), the red led blink regularly

I use CanBus shield v.1.0 + arduino one

Any ideas?

Remove R3 or cut the jumper. See here: viewtopic.php?p=18878#p18878
