Transform raw telematics data into actionable insights. Learn to map critical vehicle signals to prevent failures, optimize maintenance schedules, and reduce costly downtime.
Go beyond basic GPS tracking. A signal map allows you to use your telematics data for true condition monitoring and predictive maintenance.
A Telematics Signal Map is a documented guide that connects specific vehicle data signals to critical maintenance insights, enabling a proactive maintenance strategy.
It formalizes the process of converting raw data from vehicle sensors into a structured format for analysis. This is a foundational step for any fleet aiming to implement effective condition monitoring and leverage technologies like AI anomaly detection to predict failures before they happen.
| Failure Type | % of Total Failures | Prevention Method |
|---|---|---|
| Engine Overheat | 35% | Continuous Temp Monitoring |
| Electrical System Failure | 25% | Voltage & Amperage Alerts |
| Brake System Issues | 18% | Air Pressure & Brake Wear Signals |
| Fuel System Malfunctions | 12% | Fuel Rail Pressure Analysis |
| Hydraulic System Leaks | 10% | Fluid Level & Pressure Alarms |
A robust telematics signal map is built on three pillars: documentation, data points, and application.
A telematics signal map is most effective when it's fully integrated with your overall predictive maintenance strategy, turning data into actionable insights.
Align your signal map with other key data sources. For example, correlate engine temperature signals with your cooling system checks to predict potential overheating issues. Use vibration signals from your map to inform your vibration thresholds and track component wear. The data can also provide critical context for your fluid analysis to identify early signs of contamination. By creating these links, you build a truly predictive fleet maintenance program.
Reduction in unplanned breakdowns with predictive alerts
Faster identification of root causes for mechanical issues
Decrease in maintenance labor hours through planned service
Data-driven decisions for proactive fleet management
Engine temperature, oil pressure, RPM, load, and fault codes (DTCs) are critical for monitoring engine health and predicting failures related to lubrication and cooling.
Monitor battery voltage, alternator output, and charging cycles to predict potential battery health issues and prevent electrical failures that lead to downtime.
Track air pressure levels, brake application, and potential air leaks. This data is essential for maintaining safety and preventing DOT violations. It also links to your brake service program.
Monitor fuel consumption rates, DEF levels, and emissions fault codes to manage costs and ensure compliance with environmental regulations. This is vital for your emissions-def program.
A signal map helps avoid these common errors that can lead to missed issues and ineffective maintenance. The right process is key to reliable outcomes.
Only looking at fault codes without considering the vehicle's operating conditions (e.g., engine load, temperature).
Setting too many or too sensitive alerts, leading to "alert fatigue" where technicians ignore critical warnings.
Not refreshing the signal map as new assets or telematics systems are introduced. The map must be a living document.
Collecting vast amounts of data but failing to analyze trends or correlate signals to prevent future failures.
Successfully rolling out a new telematics signal map requires a clear, phased approach involving documentation, training, and performance monitoring.

Key questions for Maintenance Managers implementing a new telematics strategy.
A dashboard displays data, but a signal map provides the context and procedure for using that data. The map is the strategic plan that turns raw numbers into actionable maintenance tasks and alerts.
The best signals are those that relate to the most common failure modes for your fleet and asset type. Start with critical systems like the engine, brakes, and electrical system, and then expand to others based on your maintenance history and predictive models.
Involve them in the development process. Frame the signal map as a tool to simplify their work by providing clear, data-driven instructions. Emphasize the "why" behind each alert, linking it to preventing major breakdowns and improving safety. Hands-on training is crucial.
You need a robust telematics system that can collect a wide range of data, a data analytics platform to process the information, and a computerized maintenance management system (CMMS) to create and track work orders based on the alerts generated from your signal map.
