Fluid ELD
Bluetooth engine diagnostics reader for ELD, sends data to any device.

Fluid ELD Bluetooth

Plugs into the J1939 or J1708 Jbus connector and sends via Bluetooth BLE4.1 to any device the engine diagnostics data required by FMCSA for Electronic HOS compliance
including: Odometer, Engine Hours, Engine ON / OFF.

Sends periodic engine diagnostic codes as they appear that can be displayed on the device for the driver and can be forwarded by the device to the fleet management server via the cellular data plan of the device. Able to monitor simultaneously or separately the J1939 and J1708 protocols.

Easily plugged into the Jbus port via a J1708 (6pin), J1939 (9pin) or J1708/J1939 (9pin) dual pass-through connector or can be hard-wired in place. On top of the FMCSA requirements,  you can also send additional engine data such as: fuel level, fuel consumption and major engine diagnostic codes to be processed by a 3rd party application on any device and forwarded by the device to the fleet management server.
