About This Product

Be prepared for the unexpected. A diesel engine runaway, though rare, can lead to catastrophic failure when external hydrocarbons cause uncontrolled overspeeding. Protect your vehicle—and yourself—with BD Diesel’s Electronic Positive Air Shutdown (E-PAS).

By actuating the existing electronic throttle body found on modern diesel engines, the E-PAS automatically shuts off airflow in emergency situations, safely stopping the engine. Unlike other Duramax shutdown systems, BD’s E-PAS is the only solution on the market that operates without triggering a Malfunction Indicator Light (MIL) or trouble codes such as P0106. Installation is quick and hassle-free, thanks to factory plug-in connectors and a premade wiring harness—taking less than 1.5 hours. The system resets automatically after shutdown and can be easily removed for lease returns.

Stay in control when it matters most with an E-PAS from BD Diesel.

E-PAS POSITIVE AIR SHUT-OFF CHEVY/GMC 2500HD / 3500HD / 4500HD / 5500HD / 6500HD 6.6L L5P 2017-2023

How difficult is the E-PAS to install on my L5P Duramax?

Installation is a straightforward, plug-and-play process designed to take less than 1.5 hours. It requires no custom wiring or permanent modifications to your truck. — This kit is engineered for a simple installation using factory-style electrical connectors. The included premade wiring harness integrates directly into your truck's existing system without any cutting or splicing. The E-PAS module controls the L5P's factory electronic throttle body, so no custom intake piping or aftermarket butterfly valve assemblies are needed. Because it's a completely bolt-on, plug-in system, it can be easily removed, making it ideal for leased vehicles that must be returned to stock condition. No special programming or ECM tuning is required for the E-PAS to function correctly.

Will this positive air shut-off cause a check engine light on my 2022 Silverado 3500HD?

No, the BD Diesel E-PAS is specifically engineered to operate without triggering any Malfunction Indicator Lights (MIL) or setting diagnostic trouble codes (DTCs). It is the only L5P Duramax shutdown solution on the market that guarantees code-free operation. — Unlike other systems that can cause fault codes like P0106 (Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance), the E-PAS integrates seamlessly with the factory engine controls. It intelligently commands the existing electronic throttle body to close during a runaway event, a function the ECM understands without flagging an error. This prevents nuisance check engine lights and avoids the need for diagnostic tools to clear codes after an activation. Your 2017-2023 GM 6.6L L5P will remain compliant and operate as expected during normal driving.

What is the reset procedure after the system shuts the engine down?

The E-PAS system resets automatically after use. No manual reset or intervention is required. Simply turn the ignition off and then restart the engine once the emergency situation is resolved. — The system is designed for immediate readiness after an emergency shutdown event. Once the engine has been stopped by the E-PAS and the source of the external hydrocarbons (flammable vapors) is no longer present, you can simply cycle the ignition key to restart the vehicle. The E-PAS controller automatically returns the throttle body to its normal operating state, requiring no tools or special procedures. This hands-free reset is critical in high-stress situations, ensuring the vehicle can be moved or operated again without delay.

How does this system shut off the engine? Does it add a new butterfly valve?

This system does not add any new valves or create intake restrictions. It utilizes the factory-installed electronic throttle body on the 6.6L L5P Duramax engine, commanding it to close and cut off the air supply during a runaway event. — A diesel runaway is caused by the engine ingesting an external fuel source, such as hydrocarbon vapors, through the air intake, which leads to uncontrolled acceleration. The BD Diesel E-PAS (part #1036764) is an electronic controller that connects to and overrides the signal to the L5P's factory throttle plate in an emergency. When activated, it instantly closes this plate, starving the engine of the oxygen required for combustion and safely bringing it to a stop. This method is non-invasive, reliable, and avoids the potential airflow restrictions of aftermarket butterfly valve assemblies during normal driving.

What comes in the box when I order the L5P E-PAS kit?

The kit includes the main E-PAS electronic controller module and a complete, vehicle-specific wiring harness. All necessary hardware for a full installation is provided. — Inside the box for BD Diesel part #1036764, you will find the core components required to protect your L5P engine from a runaway condition. The kit is built around the central E-PAS controller, which serves as the brain of the system. It also includes a high-quality, premade wiring harness that features factory plug-in style connectors for a seamless, no-cut, no-splice installation. This ensures OEM-level reliability and makes the system easily removable for lease returns or transfer to another vehicle.
