The Advanced Custom Report templates for Trailer Power Diagnostic Reports help identify whether a tractor or a trailer has power issues. When power is disrupted, it can impact critical safety systems like trailer anti-lock braking systems (ABS) and hampers real-time location tracking. By surfacing patterns across multiple tractors or trailers, the reports help isolate the root cause of issues that lead to recurring tractor or trailer power loss so you can plan targeted maintenance for your fleet, improve reliability, and avoid downstream operational or safety risks.
To help you identify whether a tractor or a trailer has power issues, there are two templates for the Trailer Power Diagnostic Report:
-
Trailer Power Diagnostic Report: Faulty Tractors: Identify trucks that repeatedly fail to supply power to different trailers they tow.
-
Trailer Power Diagnostic Report: Faulty Trailers: Identify trailers with power issues that fail to receive power from multiple tractors.
This templates are designed to surface patterns that indicate systemic tractor or trailer faults, such as a blown fuse or damaged power connector. Since power loss alerts alone don't reveal the root cause, this report helps maintenance teams take a more targeted approach.
You can Filter, Sort, and Group By Custom Report Fields to define what qualifies as repeated failure. For example, you can focus on tractors that pulled more than five trailers within a given time range (for example, last 30 days) and failed to provide power to at least four of them in 90% of trips.
You can also Schedule a Report to be sent at designated times, so you can manage your operations and tasks more efficiently.
