Systems, methods, and apparatus for improving bus latency are described. A data communication method includes receiving a trigger actuation command from a bus master coupled to the serial bus, determining that a sequence is being executed in the slave device, and providing a trigger actuation signal corresponding to the trigger actuation command when execution of the sequence has been completed. A sequence initiation command may be received before the trigger actuation command, and the sequence may be initiated in response to the sequence initiation command. The trigger actuation command may be queued in a first queue, the sequence initiation command in may be queued in a second queue. Trigger actuation commands in the first queue may be associated with sequence initiation commands in the second queue. The sequence may be initiated in response to a sequence initiation command associated with the trigger actuation command corresponding to the trigger actuation signal.

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.

Embodiments relate to a controller operable to transmit digital data messages to a receiver via a communication link having at least a first and a second transmission path, the controller comprising a first signal terminal the first transmission path and a second signal terminal for the second transmission path.
