I hope so this is what I was told by service manager and it made me feel good to get some type of acknowledgment of any kind honestly and I thought initially it was 45 mins but after doing my own testing it timed out about 15 mins

I hear that on the engine brake im more worried about putting the excessive wear on the tow bars and the event of break away and the reserve air in the af 1 not stopping in emergencyI am not sure how long mine goes each time. What I do it cycle the door locks before big down grade and before entering into serious traffic. I find that my engine braking does about 90 percent of the work. The engine brake does not activate the AF1 as there is not change in air pressure.
Just a habit when using the ReadyBrake on another vehicle...I have a Spark as a tow car for my Sprinter, and on that car the battery has to be disconnected because if it isn't owners have reported that the brakes suddenly apply on their own (so Ford is not alone in unexpected flat tow issues that do not coincide with what the manual indicates is supposed to happen). As originally pointed out in this post, the EBB is already apparently an issue...so my thinking is if I can get a vehicle in the exact state I need it sans battery, there should technically be less change of an electronic issue. I am sure as time goes on someone will figure the unknowns out, but just looking to simplify if possible.Why would you disconnect the battery when the flat towing procedure in the manual doesn’t require that step? I’m asking because I’m genuinely curious why you think that’s necessary.
Fob in one hand, cell phone in the other and I’ll let the dog steer. That should be safe, right???Agreed, those are also very serious issues. The ratio of pull to push on the tow bar certainly leans toward more pull than push. Keep in mind the app requires cell service so I would also keep the fob handy.
That makes sense of you want to start towing woth the EBB off, assuming it’ll stay in flat tow mode with the battery disconnected as you indicated in your earlier post.Just a habit when using the ReadyBrake on another vehicle...I have a Spark as a tow car for my Sprinter, and on that car the battery has to be disconnected because if it isn't owners have reported that the brakes suddenly apply on their own (so Ford is not alone in unexpected flat tow issues that do not coincide with what the manual indicates is supposed to happen).

It is not intended for the system to lose battery power. By design a loss of power can re-engage the transfer case unexpectedly and cause abrupt mechanical failures. Officially Ford will never recommend disconnecting the battery when flat-tow operations are being performed. It’s explicitly stated to avoid doing this as well.That makes sense of you want to start towing woth the EBB off, assuming it’ll stay in flat tow mode with the battery disconnected as you indicated in your earlier post.
The BMS and shutdown of EBB are not exactly related. BMS is more for intentionally live use systems like using your radio while the vehicle is off or generator failure while the vehicle is running. Not dismissing that there is an issue with the timeout delay for EBB just it’s not wholly tied together. As far as I’m aware there’s no load shed programming that would even intentionally take the EBB out of service.Tell the battery management system that lol
As I learn more about what I know about this EBB issue I agree the ebb time out is not coming from the BMS. The EBB is in the same unit as the ABS so I'm thinking the shutdown timer is either in the ABS module are maybe there is a EBB module.The BMS and shutdown of EBB are not exactly related.
