Live Diagnostics is a vehicle rental telematics capability that provides real-time visibility into vehicle health, automatically detecting faults, usage anomalies and maintenance triggers as they occur.
By identifying issues early and prioritising servicing based on actual condition and usage, RentalMatics helps operators reduce downtime, lower fleet costs and keep more vehicles earning, without manual checks or guesswork
Our live vehicle diagnostics gives you real-time visibility into the health of every vehicle in your fleet. From engine warnings and battery issues to mileage thresholds and service intervals, RentalMatics helps you move from reactive maintenance to proactive control. No guesswork. No missed warnings. No avoidable downtime. This allows your teams to spot problems early, act faster and keep vehicles earning.
Most rental operators only discover vehicle issues when it’s too late: at check-in, on the vehicle parking lot, or worse, when a customer breaks down. Live Diagnostics changes that. With continuous data flowing directly from your vehicles, your team can detect issues early, prioritise maintenance intelligently, and keep vehicles rentable for longer. The result? Fewer surprises, lower costs and more vehicles earning revenue every day.
This isn’t just vehicle health monitoring. It’s profit protection at vehicle level.
Margins are tighter, fleets are bigger, and customer expectations keep rising. Manual checks and calendar-based servicing simply don’t scale anymore. Live Diagnostics helps you reduce unplanned downtime, avoid unnecessary workshop visits, extend vehicle life, and protect utilisation and revenue – all while stripping manual effort out of day-to-day operations and giving your teams time back to focus on higher-value work.

Having your vehicles live tracked 24/7 and every journey they take traced by RentalMatics also means you can blend this live data with your rental system and bespoke Geo-fences. This blending of data results in the creation of several fundamentally important dashboards that automatically monitor for issues with vehicles, return times, and other core operational processes.
Our ‘Live Fleet Check’ dashboard and ‘Check-In Dashboard for Vehicle Returns’ create actions for your teams that generate revenue, improve productivity and streamline operational processes.
Live Diagnostics directly supports revenue performance and cost control by reducing breakdowns, refunds, callouts and reputational damage. Smarter, condition-based servicing lowers maintenance costs, while higher vehicle availability delivers more rental days per vehicle.
At the same time, automation removes manual effort from maintenance workflows, freeing teams to focus on higher-value work. Small issues caught early prevent expensive problems later, protecting both margins and operational momentum.
