Computer hacking has been a problem for as long as computers have
been around. No matter how far technology advances, there seems to be a way to
penetrate even the most secure programs. Vehicles have come an equally long
way, and newer cars rely heavily on computer programs for vehicle diagnostics.
Most people have seen and heard about the incident that shook up
the auto industry involving German automaker Volkswagen and how it manipulated
computer diagnostics in some of its vehicles. The vehicles were advertised with
estimated EPA fuel-efficiency ratings that turned out to be bogus. Consumers
who purchased the vehicles were misled, the public was put at risk, and the
Environmental Protection Agency was plagued with questions about how easily its
emissions testing can be manipulated.
Modernized emissions testing taps into a vehicle’s on-board
diagnostic (OBD) system to test for certain conditions that have been shown to
increase harmful emissions. If, according to the OBD output, none of these
conditions is present, the vehicle successfully passes inspection. Depending on
the state, the test is run by analyzing emissions after simulated road
conditions are presented. In other instances, a technician accesses the OBD
directly, and emissions software reads the OBD data.
Since OBD is nothing more than a software program that
communicates like any other computer, it is vulnerable to outside manipulation.
It appears that this what happened when Volkswagen deliberately manipulated the
system in its vehicles for the sole purpose of circumventing emissions testing
standards. Initially, the recall was said to affect only diesel-based engines,
but it was recently expanded to include certain gas-powered models, as well.
What Exactly did Volkswagen Do?
In the case of the Volkswagen emissions hack, programmers accessed
the vehicle’s diagnostic computer system and coded it in such a way that the
vehicle performed differently under testing conditions. During normal
operation, the vehicle’s test mode (known as Dyno Mode) was in an idle state,
but when connected to emissions testing software, the vehicle would go into
“test mode” and reduce emissions to acceptable levels. In essence, the
vehicle’s emission system was hacked so that it knew when it was being tested
and was programmed to respond accordingly. However, on the road, the vehicles
in question were spewing harmful emissions at a much higher rate.
To estimate just how much Volkswagen manipulated emissions
systems, EPA testing revealed that emissions were about nine times higher than
previous readings before the hack was uncovered. Initially, Volkswagen
attempted to shoot down the EPA’s findings while questioning its testing
methods. However, the beauty of a computerized system is the fact that it is
fairly easy to trace the steps that were taken and whether or not Volkswagen
knew what it was doing. It did.
EPA Response
Volkswagen carried on its emissions hack for years before it was
thoroughly investigated by the agency. This is not the first time that
Volkswagen has been implicated in manipulating vehicles for the sole purpose of
dodging emissions standards, as it was fined more than $100,000 in the 1970s
for similar emissions manipulation. When news of the hack broke, the EPA issued
a public statement asserting that the automaker used “sophisticated software
algorithms” to thwart environmental laws and mislead consumers.
The EPA has a limited budget and would need more resources to
expand to include real-world testing. Other government agencies have backed the
EPA and stepped in to investigate. The FBI is conducting an ongoing
investigations related to Volkswagen.
Meanwhile Volkswagen faces billions of dollars in fines, and
possible criminal and civil liability. In addition, it is considering firing or
laterally shifting executives. The company issued a nationwide recall affecting
hundreds of thousands of vehicles that will cost it billions as it undertakes
complex repairs and reinstall emissions software.
Going Forward
On February 2, 2016, Volkswagen submitted a comprehensive recall
plan affecting diesel models manufactured from 2009 to 2015, and it vowed to
correct the problem. The plan must be reviewed and approved by the EPA before a
formal recall is issued. A similar plan was presented and subsequently rejected
by California regulators who stated the plan to fix vehicles was “incomplete.”
The repair plans have not yet been made public, so it’s unknown if it is as simple
as reprogramming the vehicle’s OBD, installing compliant parts, or a
combination of the two.
Meanwhile Volkswagen could face billions of dollars in fines, as
well as possible criminal and civil liability. In addition, its CEO could
resign.
The recall, which will affect nearly 1 million vehicles in the United States alone and 11 million vehicles worldwide, will cost Volkswagen billions as it performs complex repairs and reinstalls emissions software.

The EPA will keep a close
eye on all recall repairs going forward, and the situation could put increased
scrutiny on all automakers in the future.
