Plan on repairing or modifying a car in the garage this weekend? You might want to first consult a copyright lawyer.
In a development that illustrates just how much cars have become mobile computers on wheels, a privacy group is warning mechanics and car enthusiasts that tinkering with the computers that run dozens of vehicle components, without a manufacturer's approval, may constitute a copyright violation.
The Electronic Frontier Foundation, a nonprofit watchdog, says the Digital Millennium Copyright Act may prohibit modifying the code that runs these small computers, known as electronic control units (ECU). The organization is asking the US Copyright Office to exempt hobbyists and home mechanics from the law. In the petition, the EFF asks the office to eliminate the legal risks posed to vehicle owners who are "engaged in a decades-old tradition of mechanical curiosity and self-reliance."
Once every three years, the Copyright Office holds hearings to consider whether certain activities should be exempt from the DMCA's Section 1201, which restricts people from circumventing technological measures that control access to "protected works." No dates have yet been set, but a ruling is expected by mid-2015.
"The general principle at stake is that people who own a device are the ones in control of what it does, rather than be constrained to use it only in the way a manufacturer wants," says EFF staff attorney Kit Walsh. "The idea of ownership, in a way, is under threat when the law prevents you from altering a product in any way."
Needed: Access To ECUs
In the past, it may have seemed preposterous to lump a gearhead tinkering with his car under the same digital umbrella that catches people who jailbreak their phones. But today, dozens of ECUs run almost all vehicle functions, including the performance of the engine, steering and brakes. These units are run by computer code that automakers consider proprietary.
Both professional mechanics and everyday hobbyists increasingly need electronic access and expertise in ECUs and the software that runs them.
One activity, for example, that falls into a gray area under the DMCA law would be modifying an ECU in a manner that boosts engine performance or, conversely, fuel economy. Another questionable activity may be using extra memory on an ECU to create or customize a specific feature in a car's telematics unit.
At present, there's no known case in which an automaker has pursued litigation against an individual under the banner of a DMCA violation. At worst, it seems a car owner runs the risk of voiding their warranty by altering these codes. But that could change.

Interpretation Could Have Broad Impact
Implications go beyond niche aftermarket products. Security researchers studying automotive cyber threats, whose out-in-the-open work has prodded carmakers to better protect their cars, could see efforts to publish detailed findings curtailed.
Hypothetically, the EFF says, the likes of General Motors, Honda and Ford could supply ECU codes only to repair companies they contract with – or steer that business entirely to authorized dealerships. Car owners' power to choose where they want their car repaired could be diminished.
"That's exactly what can happen, and we've seen the DMCA used to extend monopolies before," Walsh said. "It gives manufacturers the power to control secondary markets by leveraging the copyright law, if it doesn't include enough of a safety valve to allow for lawful uses."

Relevant Ruling In Toner-Cartridge Case
If there's any precedent for how the Copyright Office might view the automotive petition, it comes from a ruling in a 2012 lawsuit over printer cartridges heard in the Sixth Circuit Court of Appeals, in which judges ruled the circumvention of a computer chip that ensured only authorized toner cartridges worked Lexmark printers did not violate the DMCA.
In writing the majority opinion, of the judges emphasized the broad intent of the ruling. "We should make clear that in the future, companies like Lexmark cannot use the DMCA in conjunction with copyright law to create monopolies of manufactured goods for themselves," Judge Gilbert S. Merritt wrote.
The ruling is framed in terms of accessibility. It upholds the idea the copyright law protects the original work, but says the law does not protect a security measure, such as a lockout code, designed to protect the original work.
It's not yet known how precisely another court could apply that ruling to a case involving ECUs inside a car, but the alternative, Walsh said, could imperil anyone who enjoys working under the hood of a car. "Imagine opening the hood," he said, "and you're looking at your engine and everything is in black boxes, and you don't have any of the keys for the locks."
