I'm not understanding yet. Cummins makes the motors, not the particulate filters or the urea injectors, or the wheel sensors, or any of the other sensors that inform a vehicle that it's on a dyno or open road. How are they responsible for any of that? They don't even make the fuel pumps that feed the fuel to the motor. Bosch makes those.
Culpability would fall on whoever programs the ECU to operate differently depending on dyno vs normal operation.
