2018 Ford Mustang Ecoboost Restraint system and Traction control codes

[Brian.Sestokas]

I have been having lights on the dash for ABS, Traction Control, the Restraint system, and Service Stabilitrack. I was reading that most of the time when all three of these problems are together it's a bad hub or thrust washer. Today I replaced all 4 hubs and the 2 axle thrust washers. The Passenger-Side rear thrust washer was split and the Driver-Side front hub had a bad wheel bearing. After getting them all replaced the ABS dash light went off but I still have the Restraint System failure, Stabilitrack service indicator, and Traction Control lights on the dash. When I press the traction control button it will indicate on the dash that it is off or turned back on, which leads me to believe the dash light is being caused from another system. When I ran ForsCan to check for codes I had the below results. Any help would be greatly appreciated as this is my daily driver and I cannot afford to be out of it for 3 weeks which is the dealer lead time in my area.

Ignore the ABS/traction control codes for now as those are linked to the missing RCM (Restraint Control Module), Check the fuse for the RCM as it’s not communicating at all on the bus, has anything been added under the seats lately that would of been drilled into the floor and hit a wire?

[Brian.Sestokas]

The Car is completely stock outside of replacing Rims. I did have a leaking windshield that waterlogged the BCM and required it to be replaced. I have been chasing these faults for the last 6 months since the Dealer replaced the BCM and the Windshield. They could not figure out what was causing the RCM to not communicate.

[ifrythings]

Did they replace any of the connectors or pins in the connectors or just slapped a new BCM in it? I would pull all the connectors on the BCM and check for green/white corrosion, more then likely the RCM power wire isn’t getting power from the BCM.

[Brian.Sestokas]

The dealership did not mention anything about replacing connectors. I have briefly looked at all of the connectors and didn't see any corrosion. But I also cannot find a wiring diagram for the BCM that labels what is in each connector and what pins are for what. All I found was for the entire car but didn't have connector labels.

[Brian.Sestokas]

I just removed both seats and rechecked all of the BCM connectors, including the connections under the passenger seat. I did not see any corrosion on any of the connectors. Put everything back together, and still have the communication loss with the ABS and Restraint systems. I know it's not the BCM as that is new, but maybe I need to check the Restraint Module next. The only videos I can find of getting to this module are from the 2015 model GT and it's under the center console armrest storage. The dealer told me it's behind the dash. As we know, the dealers in my area are not very goo,d and I was wondering if anyone has replaced or seen where this is on a 2018 S550 model.

[DAN1000]

Id be looking at C2280E at the bcm.
Specifically the ENS circuit
Pins are very small & you may need to remove the connector lock to see the pins
The RCM is almost directly under the center console storage bin
