What Happens When SmartLINQ Takes Action SmartLINQ immediately communicates with PACCAR’s back office by wirelessly sending detailed data about the event. PACCAR ‘s back office system translates the data into userfriendly text and graphics, and generates PACCAR Solutions web portal and email notifications.
PACCAR Solutions monitors around 800 fault codes but will only send an email notification for the high priority faults. The truck’s Primary Care Provider receives the email notification and can go online to PACCAR Solutions to view the web portal content. If you are the owner or fleet manager who is the only recipient of the notification, you would then communicate with your preferred dealerships to generate a plan for when, where and how the truck will be serviced. At this point, either you or the dealership will contact the driver to provide direction on what to do next based on the severity of the event.
Using the information from the email notification and/or the PACCAR Solutions content, the dealership begins to troubleshoot and plan for the repair while the truck is en route.
