Mack in the affected vehicles, the protection system, designed to monitor diesel engine speed and shutdown the engine should it rev excessively, may be wired incorrectly and may not operate as designed.
The short version
Mack Trucks, Inc. reported a problem with the engine diesel. Here is what owners need to know.
In the affected vehicles, the protection system, designed to monitor diesel engine speed and shutdown the engine should it rev excessively, may be wired incorrectly and may not operate as designed.
Without a system to control the engine speed, if airborne hydrocarbons (combustible vapors) enter through the air intake, excessive engine speed may result in a catastrophic engine failure and/or engine fire.
Mack will notify owners, and dealers will correct the system wiring, free of charge.
