Fault Code Indicators – What the Driver Sees
The Peterbilt SmartLINQ communication process starts when an engine or aftertreatment system fault is reported
on a SmartLINQ vehicle. The driver will see one of these dash indicators.
Stop Engine Immediately – Stop now, shut down the truck, and call for a tow if necessary. Faults that may call
for this action include those that may cause damage to the engine. Examples include: low oil pressure, high oil
temperature, and low fuel pressure.
Seek Service Immediately – Conditions such as turbocharger faults, high fuel temperatures, ECU errors, low oil
pressure, and aftertreatment faults result in this alert. These faults may lead to a derate situation and/or possible
damage to components. Some of these may be emissions-related, meaning the vehicle’s emissions are not in
compliance with EPA regulations. The appropriate action is to drive the vehicle to a nearby dealership.
Service Advised – Vehicle’s engine or aftertreatment system performance is not as expected and while the
onboard diagnostics system is monitoring the fault, it is safe to continue delivering the load. Get service at your next
opportunity. DEF quality and minor ECU faults are among the codes that may trigger this action.
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.
