If you have a UCM at ID3 you can use the UCM Firmware programming cable to upgrade the firmware in UCM ID1 as described here.

Please disconnect the target UCM from the Comfort bus (ie disconnect the white 4 way cable) and leave it connected only by the programing cable.The 4 way and 2 way connectors should be connected to the Targer UCM at ID1
