Four types of telemetry data that apply to maintenance operations: Location Usage Parameter Measures Diagnostic Trouble Codes Using Telemetry Data in Maintenance

Location Data Locate units last know location Direct field services to breakdown site In case of accident, direct emergency personnel to site Use by field service crews to locate remotely positioned vehicles Assign vehicles to nearest shop Update vehicle’s assigned maintenance location for service scheduling Most commonly used in trucking industry

Meter/Usage Data Distance GPS-Based Engine Computer Based Engine Hours Engine Computer Engine On – Off Fuel Consumption Amount consumed Fuel Percentage in Tank Idle Time

Maintenance Scheduling Most maintenance schedules driven by usage and/or time Frequent usage updates improve reliability of data for forecasting service Fuel consumption can also be used to supplement meter usage Idle can be used to vehicles that may require alternative schedule criteria Frequent usage updates also useful in justify vehicle need

Vehicle Parameter Measures Oil Pressure Engine Temperature Battery Capacity Alternator Output Fluid Levels RPM Speed Tire Pressure Seeking extreme outliers Vehicle Parameters

Use actual condition of the vehicle and real-time monitoring of systems to drive maintenance needs Vehicle specific service plans Extend service intervals until actually needed Real-time monitoring can spot breakdowns before they happen Objective is to establish thresholds for normal use Seek extreme outliers by evaluating measures against thresholds Condition Based Maintenance

Vehicles own health monitoring DTCs: Fault Code Occurrence Status Automatically alert maintenance planners to potential issues Faults trigger work requests Schedule vehicle for service Diagnostic Trouble Codes
