Question... How does the truck know the weight of the trailer?
I have heavy electric set for all my trailers... I am over 12k on all my trailers, my equipment trailer is over 20 and all this time I thought the trailers brakes were in need of repair... Maybe I have the problem too?
The air ride system measures the amount of pressure being exerted on the rear air bags. The system knows how much pressure is in each bag and can calculate the weight added to the truck.
Both the 1500 and 2500 (not sure if the 3500 has the rear bags yet but it will soon) that are equipped with the air ride system as this ability. The 1500 is a full four corner system and the 2500 is a rear only system. We have seen a few members @ the EcoD forum report that they have had a warning come up on the dash about being over loaded! And yes that gets logged for ever!
I do not think that the brake controller receives this data though.
