Truck Manufacturers Must Provide Information To Repair DEF Systems

WASHINGTON - The U.S. Environmental Protection Agency (EPA)

announced new guidelines requiring manufacturers to provide owners

and independent shops with the information they need to diagnose and repair emission control systems on heavy-duty vehicles. the EPA

reaffirmed that “the Clean Air Act (CAA) supports Americans’ Freedom

to Fix their own vehicles and equipment, regardless of vehicle or

equipment type.” EPA’s guidance affirms that, under the CAA, truck

manufacturers must provide, Americans access to the same service and repair information they make available to their own branded service centers. This includes Diesel Exhaust Fluid (DEF) and other

environmental control systems for on highway vehicles,” the agency

said. The EPA said that manufacturers must provide: Full emissions-

related service information, Training materials, OBD data and enhanced diagnostics, Passthrough reprogramming information, and

Manufacturer-specific tools for purchase. “These regulatory provisions

ensure that owners and independent repair shops can legally and

effectively repair modern vehicles and engines,” the EPA said.

Officials said that confusion over CAA anti-tampering rules cost

American truckers, farmers, and other diesel equipment operators time

and money.
