CAN Crocodile
Six contactless readers that clamp onto a vehicle's data bus without cutting a single wire. Read engine, transmission, and fuel parameters straight from CAN J1939, J1708, ISObus, or FMS — without voiding the OEM warranty, without leaving install marks, without going near the harness with a knife.
It clamps. It reads. It leaves no trace.
A direct CAN connection means stripping the wire, soldering or splicing, and creating an electrical contact the ECU may flag — sometimes triggering service mode and voiding the warranty. CAN Crocodile reads the bus via electromagnetic coupling. The ECU never knows it's there.
- Locate the bus pair— CAN H and CAN L on J1939, J1708, or whichever bus you're reading from. The vehicle's data sheet shows where; on most trucks it's behind the dash or under the chassis.
- Clamp the Crocodile around the wire pair— no stripping, no cutting. The integrated ferrite picks up the bus signal by magnetic coupling.
- Wire to your telematics gateway— CAN output (for forwarding to the gateway's CAN port) or RS-485 (for the gateway's serial input).
- Configure decoding on the gateway— your platform handles the SPN/PGN decoding using its J1939/71 high-level protocol support. Crocodile just delivers the raw bus.
CAN Crocodile · clamp installation — no wire modifications required
Six Crocodiles. Pick the one that matches your bus.
The right Crocodile depends on which bus you're reading and how dense the harness is. Use the filter to narrow down, or scan the six cards directly.
CANCrocodile
The original. The workhorse for heavy commercial vehicles.
CANCrocodile Mini
Smaller, lower power, lower message-loss rate than the classic.
CANCrocoLITE
Board-level reader for cars and light commercial — fits dense wire harnesses.
1708Crocodile
For older heavy vehicles on the J1708 standard — also reads RS-485 signals.
NozzleCrocodile
Reads injector control pulses on petrol cars — fuel consumption without CAN.
FMSCrocodile
Filtered FMS gateway — only fleet-management messages, derived "Trip Fuel Used."
The whole family, side by side.
Feeds any GPS / telematics gateway with a CAN, RS-485, or pulse input.
Certified telematics platforms
Crocodile outputs raw bus data; your gateway's platform handles the decoding via standard J1939 / J1708 high-level protocols.
