A clearer view of the whole fleet.
A developing method for preserving fleet diagnostic baselines, monitoring changes and giving repair facilities the history they need instead of starting from zero.
Give the next technician a better starting point.
An ATD-style fleet baseline organizes DTCs, freeze-frame data, relevant sensor readings and system test results. When the truck reaches a shop, the receiving technician can see what was observed before the visit.
Truck, trailer and adapter tests are documented separately, reducing the risk of confusing one unit's fault with another. When practical, the repair outcome becomes part of the next baseline comparison.
The facts a service bay can use
- Vehicle ID, mileage and operating hours
- Owner/driver concern and symptom timeline
- Module DTCs and selected freeze-frame records
- Condition-specific test results, with source and time
- Truck/trailer/adapter isolation and open questions
Proposed workflow, not a manufacturer-approved product or certified inspection program.

Make maintenance records useful while the vehicle is still in service.
When records are scattered, every breakdown becomes a fresh mystery. ATD's fleet concept aims to help owners see what happened, what was checked, and which asset needs attention next.
Vehicle & trailer records
Consistent identities, photos, connector types, inspection notes and maintenance history.
Battery & tire tracking
Trend measurements and identify developing concerns rather than collecting disconnected readings.
Driver-to-owner reporting
Practical defect reporting linked to a truck, trailer and repair follow-up.
