An apparatus and methods for testing a trailer light system including a trailer connector for coupling a first voltage to a first trailer light and a second voltage to a second trailer light, a transmission state detector for determining a vehicle transmission state, and a trailer interface module for detecting an electrical connection to a trailer at the trailer connection, and for applying the first voltage to the trailer connector and the second voltage to the trailer connector in response to the detection of the electrical connection and the vehicle transmission state being in a park state.

Trailer light testing system

The present application generally relates to a method and apparatus for application of a park hold assist system in a motor vehicle. In particular, the system is operative to receive an activation signal and to determine that the vehicle is in a park hold assist condition, such as inclined road surface, attached trailer or wheel rotation while transmission is in the park position. The system is operative to apply the hydraulic brakes in response to this condition thereby engaging a brake mechanism on all wheels.
