EFF seeks DMCA exemptions to modify and inspect car source code to make DIY auto repairs possible and keep diagnostic information accessible to mechanics

Context & Ripple Effects
In its triennial rulemaking push, the EFF asks the Copyright Office for a DMCA exemption that would let owners and independent mechanics inspect and modify vehicle source code — the same legal theory it has pursued elsewhere, including an earlier constitutional challenge to the DMCA's anti-tinkering clause. The stakes sharpened months later when Volkswagen's emissions cheating surfaced, showing that only those able to read the code could verify what a car's software actually does.
The arc continued into 2016, when the Copyright Office granted updated exemptions giving partial legal cover to reverse engineering and electronics repair — but only on a two-year trial basis, leaving vehicle-software access on a short leash rather than settled.
First-order effects
- Automakers, which filed objections in the rulemaking, face direct pressure to either open diagnostic access or argue why locked code should stay off-limits to the people who own the cars.
- Independent mechanics and DIY repairers get a concrete legal pathway proposed: inspecting and modifying vehicle code would no longer carry circumvention liability under the requested exemption.
Second-order effects
- If access is granted, diagnostic-tool makers and independent repair shops gain a lawful market for equipment and services currently gated by automaker-controlled data, shifting some leverage away from dealer service networks.
- The Volkswagen episode hands regulators and safety investigators an argument that inspection rights serve public accountability, not just hobbyists — raising the cost of blanket automaker objections.
Third-order effects
- A cycle of narrow, expiring exemptions points toward a structural fight over whether repair rights live in copyright rulemaking at all — the gap EFF targets with its broader Section 1201 lawsuit.
- As vehicles become software-defined products, the precedent set here extends beyond cars: any manufacturer controlling code inside sold hardware faces the same owner-inspection question.
The trend: Copyright exemptions and litigation, not legislation, are becoming the battleground where owners' right to inspect the software in products they own gets decided.
