Re: Cummins ECM Master Password
Posted to HD/Fleet Forum on 10/15/2020 3 Replies


Its called a Zap-it. Whipes out the old ECM password. Similar to a fleet count for changing software. You will need a valid Cummins user ID to get this.

Might have to go to dealer if you are only on fleet level Insite. Not sure. Login to read more.
