The Crocodile contactless data reader enables the retrieval of vehicle operation data without disrupting the integrity of the vehicle’s electronic systems.
Tasks solved
Engine hours monitoring (CAN)
Fuel consumption monitoring (CAN)
Remote engine diagnostics using DTC (CAN)CANCrocodile is designed for safe, contactless data reading from a vehicle’s CAN bus. It is used in vehicle telematics and GPS tracking systems to capture key operational parameters such as speed, RPM, oil pressure and temperature, fuel volume, consumption, and more.
Data is read without any direct electrical connection or damage to the CAN wires. Operating in “listen-only” mode, the CANCrocodile does not alter original J1939 messages or send signals to the CAN bus, ensuring the integrity of the vehicle’s data communication.
