The Link Polaris RZR XP900 ECU does not receive any information over the CAN bus, it does however transmit information to other devices on the CAN bus (CAN 2).
It also has a CAN bus (CAN 1) that can be used to support aftermarket CAN devices, this CAN bus is pinned out to the expansion connector as shown below.
