Our TECHNICAL SUPPORT line no longer applies to general truck diagnostics,
general truck help, or support on products unrelated to DIESELSITE.*

If you are in need of truck diagnostics, please take your vehicle to a mechanic.

In some cases, having a scan tool to provide numbers for product support is necessary.
Have a scan tool or appropriate numbers available for a technician when you call or email.
