Noregon’s Director of Product Development, Scott Bolt, presented at ATA’s Technology & Maintenance Council (TMC) Fall Meeting in Raleigh, NC. Bolt joined the slate of educational sessions for trucking equipment managers, as well as a host of activities geared for truck technicians to advance their knowledge and skills.

Bolt brought his distinguished engineering career, decades of industry knowledge, and tenure on SAE protocol committees to address ethernet-based protocol, known as DoIP (Diagnostics over the Internet and pronounced “Do ‘I’ P”) which is already implemented in the automotive industry and being phased into light, medium, and heavy-duty vehicle technology.

DoIP supports communication between on-board and off-board diagnostic systems of a vehicle and enhances diagnostics related communication between external test equipment and ECUs using IP, TCP and UDP. Its adoption is important as the industry moves toward autonomous, self-driving vehicles, because more ECUs will ‘talk,’ necessitating communication bridges be wider and more open, or free of interference.

Replacing CAN with DoIP enables higher bandwidth, which means quicker reflash times. ECU re-programming, remote & on-board diagnostics will continue to demand a faster data transfer rate. As Bolt says, “Technicians won’t have time to grab a soda during a reflash – it will be virtually instantaneous – like 200 times faster!” Additionally, the standardized data format in DoIP makes the data less prone to error and ideal for diagnostic services. For example, telematics-based ELDs, as they become more standard for vital engine data and predictive maintenance, will perform better on a DoIP network architecture.

While providing quicker and more reliable data, DoIP makes it easier to fetch diagnostic data remotely to monitor driver safety and vehicle health without requiring physical access to the vehicle. For example, live data around driver behavior patterns, temperature sensors or regulated emissions standards can help improve maintenance and repair decisions. With DoIP, a stranded driver can download a patch (the ECU communicates with the OEM site) retrieve a DTC, and the driver can possibly clear faults or make a correction until the vehicle can be serviced at a shop. And as with all cloud based information exchange, security and retooling around this protocol will continue to be researched and implemented.

What does this mean for a technician? Changes will include more security features built into the network and gateways. Those changes will require new, next-generation adapters, new software and twisted pair cable. Though 9-pin adapters will still be used, DoIP requires 5-disc pins and OEMs will decide how the pairing of two possible pin configurations will work.

As a thought leader in the industry, Noregon stays ahead of the curve with market research, data analytics and a voice-of-the-customer-driven Product Development team to educate and support technicians impacted by architecture and protocol changes affecting technicians. Be sure to keep an eye out as Noregon experts discuss these and other initiatives at various meetings, trade events, webinars, and other opportunities.
