8 Dedicated Display Screens

The CNG/H₂ module provides additional screens for monitoring temperature-compensated fuel levels and gaseous fuel engine diagnostics.

Screen 1 — CNG Fuel Level
SCREEN 1

CNG Fuel Level

Temperature-compensated arc gauge with live tank pressure, fuel temperature, GGE remaining, and distance-to-empty in one view.

Screen 2 — Fuel Performance
SCREEN 2

Fuel Performance

Flow rate (DGE/h) plus instantaneous and average economy. ECM-sourced when available, computed when not.

Screen 3 — Vehicle Data
SCREEN 3

Vehicle Data

Live engine vitals at a glance — RPM, road speed, coolant, throttle, engine hours, odometer, battery, and ambient temp.

Screen 4 — Diagnostics
SCREEN 4

Diagnostics

MIL · STOP · WARN · PROT lamp status with a scrolling DTC list in plain English. Capture and clear faults from the dash.

Screen 5 — Fuel Pressure
SCREEN 5

Fuel Pressure

Regulator health at a glance. Tracks both tank side high-pressure and engine-side low-pressure to alert of potential regulator anomalies and failures.

Screen 6 — Driving Dynamics
SCREEN 6

Driving Dynamics

Composite driver score with five sub-categories — accel, brake, speed, fuel, idle. Rolling event counts for hard brakes, accels, and corners.

Screen 7 — Eco Mode & System
SCREEN 7

Eco Mode & System

Cummins Eco Mode and derate state at a glance. ECM- and FSCM-reported economy with computed cross-check.

Screen 8 — Trip Log
SCREEN 8

Trip Log

Two independent A/B trip counters in DGE/GGE.

Enhances OEM Cluster Capabilities

Enhances OEM Cluster Capabilities

The CNG/H₂ module is a software upgrade to any Fleet Witness unit. It unlocks capabilities that no standard telematics system and no OEM instrument cluster can match.

Temperature-Compensated Fuel Level

Uses the ideal gas law to calculate true fuel level from both pressure and temperature. Pressure-only gauges read 15–20% off in extreme weather. Fleet Witness reads within 2%.

Dual Pressure Monitoring

Regulator health at a glance. Tracks both tank side high-pressure and engine-side low-pressure to alert of potential regulator anomalies and failures.

OEM & Packager FSCM Integration

Bidirectional communication with Fuel System Control Modules. See FSCM fault codes on-screen, monitor fuel over-temperature, detect leaks between key cycles, and control Eco Mode from the gauge.

Cylinder Inspection Tracking

Tracks up to 8 CNG cylinders per FMVSS 304 and NGV2-2018 requirements. Alert states: OK → Due Soon → Overdue → Expired. Never miss a compliance deadline.

Leak Detection Between Key Cycles

Monitors pressure decay when the vehicle is off. Catches slow leaks that would never trigger a check-engine light — before they become a safety event or compliance violation.

Hydrogen Ready — Same Platform

As your fleet transitions from CNG to hydrogen, Fleet Witness transitions with it. The software is equipped to monitor gaseous fuel pressure sensors up to 350 bar (10,000 psi) with corresponding ideal gas law compensation algorithms for either fuel.
