Status quo of critical tampering techniques and proposal of required new OBD monitoring functions. Deliverable D3.2
report
Pollutant emissions of road vehicles have reduced significantly thanks to the development and
application of effective and often complex emissions control systems. Tampering of these systems
leads to elevated tail-pipe emissions up to uncontrolled levels of vehicles of decades ago. Tampering
poses a large environmental risk because a small share of tampering potentially can lead to a
significant increase of the EU fleet average emissions.
For the EU H2020 project DIAS, a market assessment has been conducted and reported (DIAS
Deliverable 3.1) which included a risk assessment to determine which tampering poses the largest
environmental risk. The result of this assessment is a matrix of vehicle tampering combinations to be
tested which contains passenger cars, trucks and non-road mobile machinery with diesel engines and
a passenger car with a petrol engine on one side and the different variants of tampering on the other
side: emulators, ECU flashing, sensor modification and OBD deletion devices.
The test programme is conducted to determine the working principles of tampering. Based on this,
requirements are defined for measures that are to be developed to counter existing tampering
attempts by prevention and detection. Detailed results of the test program, such as descriptions of
how the tampering works, what vehicle signals are affected and how tampering can remain
undetected are reported in a separate confidential report (D2.2).
