Abstract
A method for performing vehicle remote diagnosis is provided. A diagnostic device sends a first controller area network (CAN) bus message to a device connector. The device connector encapsulates the first CAN bus message received into a first data packet and sends the first data packet to a vehicle connector through remote communication. The vehicle connector decapsulates the first data packet into the first CAN bus message and sends the first CAN bus message to a target vehicle. The vehicle connector receives second CAN bus messages and filters the second CAN bus messages to obtain a CAN bus diagnostic message, and the second CAN bus messages are sent by the target vehicle in response to the first CAN bus message. The vehicle connector encapsulates the CAN bus diagnostic message into a second data packet and sends the second data packet to the device connector.
