Diagnostic Trouble Codes (DTC)
Take the trouble out of troubleshooting and automate the process of reporting vehicle malfunctions.


Get Immediate Insight About Potential Maintenance Problems Using DTCs
As a fleet manager, you want to keep vehicles on the road, in optimal operating condition, for as long as possible to maximize ROI. Preventative Maintenance plans play a significant role, but what about unexpected problems that arise between regularly scheduled maintenance? That’s where Diagnostic Trouble Codes (DTCs) can help.
DTCs are codes prescribed by the Society of Automotive Engineers (SAE) to track problems detected by a vehicle's on-board computer. DTC reporting and notifications, included with the Lytx Fleet Tracking Service1, give users a real-time view of vehicle diagnostics, fuel, odometer, tire pressure, vehicle speed, and more to quickly identify and resolve maintenance issues.
How It Works
The Lytx DTC feature takes the responsibility for reporting mechanical issues off of drivers and relies on the onboard telematics system to automatically relay the DTC code to the fleet manager in real time.




DTCs, combined with a comprehensive preventative maintenance program, can keep your fleet running at optimal performance with minimal frustration. A comprehensive fleet management system like Lytx makes DTCs and preventative maintenance easier than ever by automating the process of reporting vehicle malfunctions (and reducing the risk of mistakes).
Our fleet management system automatically relays DTCs in real time, allowing you to monitor and address mechanical issues, as well as perform preventive maintenance by tracking wear and tear, while vehicles are operating.
