Abstract
A backup aid system () for detecting the presence of a trailer () includes a trailer connector () and a backup aid controller () that has an input () electrically coupled to the connector (). The backup aid controller () monitors a voltage level at input (). When the voltage level is above a first predetermined voltage, the controller () generates a backup warning signal. When the voltage is below a second predetermined voltage, the controller () disables the backup warning signal. Also, the system may monitor the voltage in between the first predetermined voltage and the second predetermined voltage to determine the presence of a lamp fault such as outage or corroded contacts.
