Warnings (WAR)
Never miss a critical vehicle warning
Modern vehicles generate hundreds of diagnostic messages, warning lamps and system alerts.
Some require immediate action, while others simply indicate that maintenance should be planned.
The Squarell Warnings Parameter Group collects important warning information from multiple vehicle systems and converts it into one harmonised event message, allowing fleet applications to react quickly and consistently.
Instead of monitoring dozens of independent vehicle systems, applications receive one central stream of meaningful vehicle warnings.

- Real-time vehicle alerts
- Predictive maintenance
- Workshop planning
- Driver notification
- Fleet dashboards
- Vehicle availability monitoring
- Remote diagnostics
- Maintenance prioritisation
- Technical support
Key Parameters
Warning Classification
Every warning is classified according to its urgency.
Typical parameters include:
- Warning Priority
- Warning Category
- Active / Cleared Status
- Warning Source
- Event Time
- Vehicle Status
This allows applications to distinguish between informational notifications and critical warnings requiring immediate action.
Engine Warnings
Examples include:
- Low Oil Pressure
- High Coolant Temperature
- Low Coolant Level
- Engine Protection Active
- Engine Derate
- Engine Shutdown Warning
Brake & Safety Warnings
Examples include:
- Brake System Warning
- ABS Warning
- EBS Warning
- Parking Brake Warning
- Brake Wear Warning
- Stability Control Warning
Exhaust & Emission Warnings
Examples include:
- DPF Warning
- Regeneration Required
- SCR Warning
- AdBlue Low Level
- High NOx Emissions
- Emission System Fault
Tyre Warnings
Examples include:
- Low Tyre Pressure
- High Tyre Temperature
- TPMS Fault
- Rapid Pressure Loss
Electrical Warnings
Examples include:
- Low Battery Voltage
- Charging System Fault
- Alternator Warning
Driver & Operational Warnings
Examples include:
- Door Open
- Seat Belt Warning
- Driver Card Missing
- Remaining Driving Time Critical
- PTO Active
- Trailer Disconnected
The complete Parameter Group and parameter definitions are available to Squarell partners.
Integrated Warning Sources
The Warnings Parameter Group combines relevant warning information from several Squarell Parameter Groups, including:
- Tell-Tales
- DM1 Active Diagnostic Trouble Codes
- Engine Data
- Brake Data
- Truck TPMS
- Exhaust Data
- Maintenance
- Driver-related Parameter Groups
Applications therefore receive one harmonised warning interface instead of monitoring each Parameter Group individually.
The complete Parameter Group and parameter definitions are available to Squarell partners.
Visualisation
Warnings can be displayed as a prioritised event list.
Each warning includes:
- Severity
- Category
- Description
- Vehicle
- Active / Cleared
- Source System
- Recommended Action
Fleet operators can therefore immediately determine which vehicles require attention and which warnings can be scheduled for the next maintenance visit.
Business Value
The Warnings Parameter Group helps fleet operators to:
- detect critical events immediately
- reduce response times
- prevent roadside breakdowns
- improve workshop planning
- prioritise maintenance
- reduce downtime
- improve fleet safety
- simplify dashboard development
- provide one consistent warning interface across mixed fleets
Why Squarell?
Different vehicle manufacturers generate warnings in different ways.
Some warnings originate from dashboard tell-tales, others from J1939 diagnostic messages, TPMS, brake systems or exhaust aftertreatment.
Squarell combines these independent warning sources into one harmonised Parameter Group, allowing fleet applications to monitor vehicle health through a single interface instead of processing multiple OEM-specific warning systems.
