Kvaser Leaf Light CAN BUS Simulator problems
The termination is not correct
The termination resistors' values are too low. They should be 120 ohm, not 60 ohm (for a total ohmic resistance of 60 ohm - if you measure between CAN-H and CAN-L with a multimeter with all power off you should get 60 ohm. At the moment you would measure 30 ohm).
Lonely CAN bus device
If &quot;Fiat Stilo instrument cluster&quot; only contains a single device, it is important that the CAN adapter is participating on the CAN bus (for example, setting the ACK bit). In CANKing this is done by setting Driver Mode to Normal (not Silent):

However, as this is the default setting, it is probably already set to Normal. If the actual Kvaser adapter does not support silent mode then the setting does not matter if the version of CANking is sufficiently new, version 5.0 or later (2009-06-09).
