System and method for testing a tractor trailer

A tractor trailer testing system, comprising:

• a housing including a seven-way tractor trailer plug port electrically connectable to a seven-way tractor trailer plug corresponding to a first circuitry of a tractor trailer, a two-pole charge port electrically connectable to a two-pole charger corresponding to a first lift gate circuitry of a tractor trailer, a single-pole charge port electrically connectable to a single-pole charger corresponding to a second lift gate circuitry of a tractor trailer, a service air line port electrically connectable to a service air line of a tractor trailer, and an emergency air line port electrically connectable to an emergency air line of a tractor trailer;
• a circuit board coupled to the seven-way tractor trailer plug port, the two-pole charge port, the single-pole charge port, the service air line port, and the emergency air line port, the circuit board to generate a first electrical signal corresponding to an electrical output of the first circuitry, a second electrical signal corresponding to an electrical output of the first lift gate circuitry, and a third electrical signal corresponding to an electrical output of the second lift gate circuitry, and the circuit board to generate a first pressure signal corresponding to a pressure output of the service air line, and a second pressure signal corresponding to a pressure output of the emergency air line;
• an electronic device including a graphic user interface comprising a plurality of meters, the plurality of meters corresponding to the first circuitry, the first lift gate circuitry, the second lift gate circuitry, the service air line, and the emergency air line, each of the plurality of meters to display the corresponding electrical signal or pressure signal of the first circuitry, the first lift gate circuitry, the second lift gate circuitry, the service air line, and the emergency air line;
• a wireless transceiver coupled to the circuit board, the wireless transceiver to transmit the electrical signal and the pressure signal generated by the circuit board wirelessly to the electronic device;
• and
• a memory to store the transmitted electrical signal and pressure signal.

A method of testing a tractor trailer, comprising:

• connecting a seven-way tractor trailer plug of a tractor trailer to a seven-way tractor trailer plug port of a housing;
• connecting a service air line of the tractor trailer to a service air line port of the housing;
• connecting an emergency air line of the tractor trailer to an emergency air line port of the housing;
• powering the tractor trailer while the seven-way tractor trailer plug, the service air line, and the emergency air line are connected to the housing;
• querying an electrical signal of the seven-way tractor trailer plug, a first pressure signal of the service air line, and a second pressure signal of the emergency air line;
• receiving the electrical signal, the first pressure signal, and the second pressure signal;
• wirelessly transmitting the electrical signal, the first pressure signal, and the second pressure to an electronic device;
• and
• displaying the electrical signal, the first pressure signal, and the second pressure signal on the electronic device.
