The various available device modes are:


OBDII Device modes:

  • OBDII mixed mode: This is the default mode present in the device. This mode allows the device to interact with the ECU of the vehicle and access the vehicle information such as odometer, seat-belt, diagnostics, etc.


  • OBDII listen mode: The listen mode is a mode where the device doesn’t interact with the ECM directly to access the vehicle information, it will only be able to access the information provided by the vehicle. 


Note: This mode can be activated for vehicles that have on-board diagnostics systems like Onstar, Applus, ATEEL etc present in the vehicle which runs timely diagnostics checks to monitor the vehicle health.



JBUS Device modes:

  • JBUS mixed mode: This is the default mode present in the device. This mode allows the device to interact with the ECU of the vehicle and access the vehicle information such as odometer, diagnostics, etc.



HardWired device modes:

  • 2-wire: The hardwired 2-wire solution uses 2-wires (power and ground) and relies on the vehicle movement to detect trip start and trip end. Our 2-wire hardwired solution supports idling for about 5 minutes. 


  • 3-wire:  A 3-wire solution uses 3-wires (power, ground and ignition line) and supports better trip detection as the third wire is connected to the ignition line of the vehicle. It can also support Idling for longer duration as opposed to the 2-wire connection.


Non-OBD mode: Certain vehicles have installed equipment like wheelchair lifts that don't allow the usability of the equipment when the devices are plugged in. The device can be configured to operate in the non-OBD mode that terminates the communication with the ECM and allows the equipment to function properly.
