While I understand the idea, I'm not sure it'll wind up with an end result of EBB assist during flat-tow. Generally the existing standard was that systems would need to supply vacuum pressure to allow boosted operation on those systems that require it but otherwise no vehicle side boost is...
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...
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...
Just a small interjection about this. The entire lineup of the 2021 F-150 uses EBB, it’s not offered at all with vacuum assist. I’ve posted in this thread a list of vehicles with either standard or engine dependent EBB systems that also are capable of being flat towed
Also the 2022 Expedition...
PM me your VIN I’ll take a look tonight if there’s a cloud submitted DTC for it. I don’t think any of your changes should have caused this.
Edit: Sorry I forget we are in the ForScan thread. Can you see any codes that may be pertinent to this? I’d like to know the responsible module and what...
Have you thought about the 14th gen tie rods at all? I may have missed it if so but those are what’s used on the upgraded rack. On the Raptor they changed the knuckle with an F-150 Raptors with minor tooling difference but not sure of the specific differences. Basically a lot of similarities overall
Front Axle Disconnect System Operation
Principles of Operation
NOTE: Front axle disconnect is associated with open type front differential - DANA M190.
The FAD (front axle disconnect) distributes torque across the front axle halfshafts for 4WD operation when requested. It reduces the drag and...
There are two M190 variants. Both are open but one has a Front Axle Disconnect and the other does not. Unsure of what trims get what I never dig far on it. But basically the FAD is the M190’s version of the locking diff. Maybe it’s even marketed that way I don’t know for sure. With the FAD off...
