On my 2015 Ram Eco-Diesel I had these warnings come on last night all at the same time. The truck runs fine, not sure what it could be. I am thing a short in the wiring or somthing got wet. The only other issues I have been having is my rear center light needs to be replaced and it is flashing not sure if this is releated or not. Any help is appricatied. Here are the warnings again

Service air suspension system
Service Trailer Brake system
Service Electronic Braking system
and the traction light came on as well.

 

Any other codes stored? Could be as simple as one failed sensor.

 

No, no other codes. I am just not sure what sensor could have failed.

 

3 of 'em are talking about the brake system..... Can you look at live data? See what wheel speed sensors are showing? Is there a fluid level sensor on the master cylinder?

 

I will see what I can to to read the live data, and I will check to if there is a fluid level sensor. Thank you for the help
