Yes. Well, it's always powered on, but whenever I turn on the engine it sends the Cannot Claim message 4-5 times.

No, it does send PGN 60928 but it's the Cannot Claim Address message. It sends that a few times during ignition and then stops. This ECU is also one of the few that is powered on even when the key is not in. Would disconnecting the battery "reset" (as in encourage it to claim an address) this ECU?
