How Wireless Fleet Management Works

The Link2 emergency vehicle diagnostics module connects directly to your vehicle’s J1939 port and records vehicle data received from the CAN bus network. Information is captured and transmitted automatically to the Link2 servers and viewed through the online dashboard. Receive alerts on your mobile device when your vehicle needs attention. Link2 is compatible with all heavy duty trucks manufactured after 2001.

For each vehicle, you will need to purchase a Link2 module and Vehicle Dashboard Subscription.
