NEXIQ First-Link™ is an application that provides important features to the drivers and service technicians of commercial vehicles and equipment. These features help the driver connect the mobile device to the diagnostic port; they also monitor the vehicle's health status and increase the vehicle's uptime. If a Check Engine Light is illuminated, the application assists the driver to understand the cause so that he can seek assistance (i.e., service and repair), if needed. Service technicians can utilize the information gathered by the application to aid in vehicle service and repair.

Features include:

• Faults – Active and Inactive fault codes present at the time of connection are displayed.
• Vehicle Specs – Vehicle information including VIN, ECU software and hardware information is displayed.
• Life / Trip – Displays trip-specific information related to fuel usage, miles, maximum speed, cruise control speed, hours of operation, etc.
• Parameters – Displays parameters specific to the modules on the vehicle (e.g., engine, transmission, etc.)
• Report – Generates a session-specific report containing vehicle information (i.e., faults, vehicle specs, parameters, and life/trip information); can be uploaded to the cloud, emailed, etc.
• Sharing - Enables the driver to share vehicle information gathered to dispatch, service providers, etc.
• OnCommand® Support - Optional feature to allow users to upload health reports to the OnCommand® servers.
• Blue-Link Mini firmware update to v1.09, if the adapter has older firmware.
