Lack of CAN message documentation is a problem for use of components in projects, but that's very different from repair. Is any more CAN documentation (than Ford has released) needed to repair a Mach-E using this drive unit?CAN is an anti-repair-rights moat that needs to get filled in with dirt by Congress.
Not personally, no. But then I don't have a Mach-E service manual. If you're seriously interested, cough up $20 USD for a one-month subscription to service documentation for this vehicle model from a third-party publisher (such as AllData), or make friends with an employee of a service business (Ford dealership or otherwise) with a subscription to full Ford service documentation, preferably direct from Ford (which published through Working...).What CAN documentation? Are you aware of any?
