Method and apparatus for adjusting trailer electrical load limits

A method of determining whether a light on a trailer is illuminated from within a passenger compartment of a vehicle having an electrical connection with the trailer, the method comprising:

• determining a first light configuration associated with the trailer;
• determining an electrical load profile for a terminal in the electrical connection between the vehicle and the trailer based on the first light configuration of the trailer, wherein the electrical profile for the terminal includes at least a power requirement for the light on the trailer and the terminal associated with the power delivery therefor;
• monitoring a level of current at the terminal in the electrical connection;
• informing a user in the passenger compartment that the light is not illuminated when the level of current at the terminal is less than a threshold current level.

A device for determining whether a light on a trailer is illuminated from within a passenger compartment of a vehicle having an electrical connection with the trailer, the device comprising:

• a trailer tow module that determines a first light configuration associated with the trailer;
• a terminal in the electrical connection between the trailer and the vehicle,
• wherein said trailer tow module determines an electrical load profile for said terminal based on said first light configuration of the trailer,
• wherein the electrical profile for the terminal includes at least a power requirement for the light on the trailer and the terminal associated with the power delivery therefor
• wherein said trailer tow module monitors a level of current at said terminal in the electrical connection and
• wherein said trailer tow module informs a user in the passenger compartment that the light is not illuminated when the level of current at the terminal is less than a threshold current level.
