Systems, apparatuses, and methods disclosed provide for tailoring responses to fault data generated during a service event. A method includes determining that a service event for a vehicle has started based on an indication from an off-board diagnostic service tool, interrupting transmission of a fault message during a time period after the service event for the vehicle has started and before the service event for the vehicle has ended, and determining that the service event for the vehicle has ended.

Service event response tailoring

A method includes receiving registration information regarding a telematics unit and a respective control system for a plurality of equipment pieces; receiving a seed from a control system of a first equipment piece via a telematics unit of the first equipment piece based on receiving a telematics session request by the control system of the first equipment piece; authenticating the telematics unit and the control system of the first equipment piece based on information included with the seed and the registration information; generating a first encrypted key and a second encrypted key based on the authentication; providing the first key to the telematics unit for the first equipment piece; and providing the second encrypted key to the control system of the first equipment piece via the telematics unit of the first equipment piece to establish a data communication channel.

System, method, and apparatus for secure telematics communication

Systems, apparatuses, and methods for wirelessly updating electronic control unit configuration can include determining operation parameters to be changed of an electronic control unit of an equipment, and generating a write package including the operating parameters to be changed. The systems, apparatuses, and methods include transmitting the write package to the equipment. The write package causes the electronic control unit to change the operation parameters upon verifying that the operation parameters are applicable to the equipment based on values of the parameters. In response to determining that the operation parameters are not applicable to the equipment, the write package can be discarded.

Wireless ECU configuration updating

Systems, apparatuses, and methods disclosed provide for tailoring response to fault data generated during a service event. The method comprises determining fault data for a vehicle continually, determining that a service event for the vehicle has started, interrupting transmission of fault message during a time period after the service event for the vehicle has started and before the service event for the vehicle has ended, and determining that the service event for the vehicle has ended.

A method includes receiving registration information regarding a telematics unit and a control system for each equipment piece in a plurality of equipment pieces; receiving a seed from a control system via a telematics unit for a particular equipment piece in the plurality of equipment pieces responsive to reception of a telematics session request by the control system for the particular equipment piece of the plurality of equipment pieces; authenticating the telematics unit and the control system for the particular equipment piece based on information included with the seed and the registration information; generating an encrypted key responsive to the authentication; and providing the encrypted key to the control system via the telematics unit to establish a proprietary data communication channel from the control system to the processing circuit via the telematics unit for the particular equipment piece.

Systems, apparatuses, and methods disclosed provide for wirelessly updating engine control unit (ECU) configuration. The method includes determining parameters to be changed on an engine control unit of an equipment, generating a write package including the parameters to be changed, and transmitting the write package to the equipment over the air through a cloud connected application system.

Systems and methods to update the calibration data of a control system includes a calibration system. The calibration system includes a first cloud connected application system structured to communicatively couple to a second cloud connected application system, determine, via at least one of the first cloud connected application system or the second cloud connected application system, a calibration update request corresponding to a control system, generate custom calibration data including preference data based on at least one of the calibration update request or the preference data, and provide the custom calibration data during at least one of an active engine state or an inactive engine state, wherein the custom calibration data is transmitted from the second memory portion to the first memory portion in response to the inactive engine state.
