SPN 5443. Engine coolant 119 °C. Engine bay ambient 71 °C. The DTC fired five seconds before the warning lamp.

Vehicle CAN bus is the richest signal stream on a fleet — and the hardest to make useful. iMatrix decodes J1939, CANopen, and raw CAN at the edge with FC-501, generates DBC databases with Wayne AI, and correlates every fault with the cabin and cargo conditions around it.

Decode at the edge. Decide in the cloud.

🔌

Dual CAN at the gateway

Two physical CAN ports on FC-501 — read OEM J1939 traffic and your own CANopen network simultaneously without contention.

🧠

DBC-driven decode

Upload a DBC file; iMatrix CAN Management auto-generates the embedded code so the gateway publishes signals — not raw frames — to the cloud.

🌡

Ambient correlation

NEO-1 and Sentry-1 add cabin temperature, humidity, and door state alongside CAN signals. "Was the engine bay 60 °C when this DTC fired?" — answered.

FC-501 is the CAN engine. NEO-1 and Sentry-1 are the witnesses.

CAN tells you what the vehicle thinks is happening. Environmental sensors tell you what was happening around it. Together, they explain the events that look anomalous on the bus alone.

DBC in. Production firmware out. Decoded signals in the cloud.

The painful part of CAN integration is the embedded code that converts raw frames into signals. Wayne AI generates it — and iMatrix Cloud knows how to display every field automatically.

1 · Author a DBC

Use the iMatrix DBC editor (or import an OEM-supplied .dbc). Wayne AI suggests signal mappings from prior fleets and auto-flags physical-range conflicts before deployment.

2 · FC-501 decodes at the edge

Embedded firmware compiled from the DBC runs on FC-501. Only decoded, named signals are uplinked — keeping cellular usage low and the cloud schema clean.

3 · Cloud correlates with environment

NEO-1 and Sentry-1 events arrive on the same timeline. "DTC + bay temperature + hood-open" becomes a single root-cause record instead of three disconnected logs.

4 · Wayne AI flags anomalies

340× faster than manual analysis. Wayne surfaces failure modes — "low fuel pressure clusters with high ambient temp on this engine model" — without you writing the query.

Wherever CAN matters more than GPS.

🚛

Class 7/8 J1939

Engine, transmission, after-treatment SPNs decoded live. DTC alerts fire to the maintenance queue with ambient context.

🚜

Off-highway CANopen

Construction, agriculture, mining. iMatrix decodes proprietary OEM DBCs — no source code from the OEM required.

🔋

EV BMS over CAN

Battery pack SOC, cell voltages, and thermal events. NEO-1 inside the pack adds independent ambient verification.
