The SmartCONNECT Module has four methods of communication with the ES-Key™ and J1939 CAN networks on your vehicle. Local wireless, wireless over the internet, LAN and USB connections allow you to perform all ES-Key™ Professional software functions as well as run chassis diagnostics for the engine, transmission and ABS systems. Class1 engineers designed the SmartCONNECT Module to be backward compatible with any existing ES-Key™ system so that current ES-Key customers can take advantage of the newly available connectivity options.

With SmartCONNECT there are no physical connection requirements. A user can simply log on to the vehicle using a wireless connection locally or over the internet. It allows real time bi-directional communication with the vehicle. Not only can you receive all ES-Key™ electrical system data and chassis related CAN messages, you can send CAN messages to the vehicle as well. It gives you the ability to upload or download ES-Key™ program files and perform all other diagnostics that were formerly featured in the “dial up” modem.


SmartCONNECT allows up to 4 home networks to be set up to ensure smooth communication to and from the vehicle is never too far away. It can be used in conjunction with a property conjured cellular “hot spot” to maintain connectivity (in areas of good coverage). When wireless is unavailable SmartCONNECT is there. With its USB and LAN connections you always have a way to connect.
