The BD Diesel E-PAS Positive Air Shut-Off (1036753) is a vital safety upgrade designed specifically for 2019–2024 Cummins 6.7L Cab & Chassis trucks. This electronic shut-off system helps prevent diesel engine runaway—a dangerous condition where the engine continues to run uncontrollably due to the ingestion of flammable vapors, often during turbo failure or exposure to external combustibles. The E-PAS unit automatically cuts off the air supply to the engine in such scenarios, effectively shutting it down to avoid catastrophic damage or safety hazards. Engineered for quick response and reliable operation, the BD Diesel E-PAS integrates seamlessly with OEM systems and includes all necessary components for straightforward installation. Its robust design and precise control make it an essential addition for fleet operators and service vehicles where safety and reliability are paramount.
