Abstract

A method for remotely accessing at least one of at least one CAN node arrangement of a CAN bus arrangement associated with the vehicle during vehicle operation, the CAN bus arrangement being associated with a CAN gateway arrangement for coupling to an external network, inn which the method includes the steps of communicating an initialization control message from the CAN gateway arrangement to the at least one CAN node arrangement using the CAN bus arrangement, the initialization control message including a CAN node arrangement identifier code, comparing the CAN node arrangement identifier code with a unique CAN node arrangement identifier code stored at each of the at least one CAN node arrangement for determining a selected CAN node arrangement based on the CAN node arrangement identifier code and the unique CAN node arrangement identifier code, processing the initialization control message using the selected CAN node arrangement, communicating a data addressing message from the CAN gateway arrangement to the selected CAN node arrangement, the data addressing message including at least one memory address of the data to be at least one of accessed, controlled and retrieved, commun…
