CAN Monitoring
CAN bus monitoring reads data directly from the vehicle's internal network, unlocking parameters that standard OBD-II cannot access. Monitor transmission status, AdBlue levels, PTO engagement, brake pad wear, and manufacturer-specific signals.
Key capabilities
What CAN Monitoring does for your fleet.
Manufacturer-Specific Parameters
Access data that vehicle manufacturers expose on the CAN bus for their specific models — fuel consumption from the ECU, AdBlue levels, PTO status, refrigeration unit state, and more.
High-Frequency Sampling
Sample CAN data at intervals down to 100ms for applications where real-time precision matters, such as live load monitoring or detailed engine performance analysis.
Custom Channel Configuration
Define which CAN channels to read and how to interpret the raw values using Fleetbooks' built-in decoder library or your own custom channel definitions.
Who uses it
CAN Monitoring is used across industries wherever fleet visibility and control matter.
Heavy Truck and HGV Fleets
Monitor tachograph integration, truck-specific fault codes, and refrigeration unit status for commercial heavy goods vehicles.
Bus and Coach Operators
Read passenger door status, HVAC system state, and real-time engine parameters for route compliance and passenger comfort management.
Construction and Utility Vehicles
Track PTO engagement, hydraulic system pressure, and body position sensors on equipment that has no standard OBD-II interface.
