Methods, systems, and devices for simulating a connection between a vehicle connector and an accessory system

A connection simulator system for simulating a connection between a vehicle and an accessory system, comprising:

• a controller area network (CAN) bus connector configured to connect with the accessory system;
• an electronic control unit (ECU) electrically connected to the CAN bus connector and including:
• a plurality of transceivers configured to transmit and receive CAN signals, and one or more microprocessors (MCUs) electrically connected to the plurality of transceivers and configured to:
• transmit, via one or more transceivers of the plurality of transceivers, CAN signals simulating communication with and/or from the accessory system,
• receive, via another one or more transceivers of the plurality of transceivers, the CAN signals simulating communication with and/or from the accessory system, and
• transmit, via the one or more transceivers of the plurality of transceivers, the received CAN signals simulating communication with and/or from the accessory system to the one or more transceivers and to the another one or more transceivers;
• and
• a void seal, when attached to the CAN bus connector prevents the accessory system from being connected to the CAN bus connector, and when detached from the CAN bus connector, the one or more MCUs stop transmitting the CAN signals simulating communication with and/or from the accessory system.

A connection simulator system for simulating a connection between a vehicle and an accessory system, comprising:

• a vehicle bus connector configured to connect with the accessory system;
• a plurality of transceivers including a transceiver and a simulator transceiver, the plurality of transceivers configured to transmit and receive signals;
• one or more microprocessors (MCUs) electrically connected to the vehicle bus connector and the plurality of transceivers and configured to:
• transmit, via the simulator transceiver, signals simulating communication with and/or from the accessory system,
• receive, via the simulator transceiver, the signals simulating communication with and/or from the accessory system;
• and
• a void seal, when attached to the vehicle bus connector prevents the accessory system from being connected to the vehicle bus connector, and when detached from the vehicle bus connector, the one or more MCUs stop transmitting and receiving the signals simulating communication with and/or from the accessory system and enable or start transmitting and receiving signals, via the transceiver, to and/or from the accessory system.
