Interactive Diagnostic Aid available on Truck & Trailer Specialties web site.
Truck & Trailer Specialties is a company with a heritage and reputation of providing support to our customers. In continuance of this tradition, we have developed a diagnostic tree which is available 24/7 to guide users through the diagnostic process for identifying and repairing problems in truck hydraulic systems and material controllers (consoles). The process is fairly generic and laid out in a step by step concise method. We encourage you to familiarize yourselves with the process prior to winter season so it will be of more value when needed.
