Its original name is an ALDL, short for Assembly Line Diagnostic Link, or Assembly Line Data Link. But most call an ALDL the OBD-II port because it provides everyone from engineers at proving grounds to dealership technicians to shade tree mechanics a connection to the vehicle's software and diagnostic systems. And soon, battery electric as well as hydrogen fuel cell vehicles will offer similar access.

Wait… EVs don't already have that? Not all of them, no. And the various manufacturers' systems differ from each other in both connectivity and scope, which makes troubleshooting an errant EV that much more difficult. That, as you can imagine, causes more than a few headaches for the good folks that service EVs.

Modern on-board diagnostics, or OBD-II, became a standardized and mandatory part of every automobile sold in the United States starting with the 1996 model year. And all vehicles, from a Ford Escape to a Ferrari SF90, needed one. But this mandate exempted EVs and other alternatively powered vehicles.

California is far and away the country's largest adopter of plug-in electric vehicles. Because of the state's ability to regulate its own air quality and spurred on by a large economy and plenty of affluent residents, the EV has gained plenty of traction in the Golden State. So much so that last month, California met its goal of having more than 1.5 million clean vehicles on the road two years ahead of schedule.

"No other state in the nation is doing as much as we are to accelerate our electric and zero emissions future," said California Governor Gavin Newsom. "California is setting the bar for climate action—and we're achieving our goals years ahead of schedule thanks to unprecedented investments secured in partnership with the legislature. We're making real progress on the world's most ambitious plan to end the tailpipe so our kids and grandkids are left with a cleaner, healthier planet."

California's Air Resources Board (CARB) began its Zero-Emission Vehicle (ZEV) program in 1990 with the intent of ameliorating the state's severe smog problem. By the early years of this century, air quality had improved to the point where CARB could begin using the ZEV regulations to help drive down climate emissions.

On Thursday when the California Air Resources Board gathers for its monthly meeting, it's widely expected it will approve a ban on new vehicles with internal combustion engines, set to go into effect in 2035. The state has been a leader in accelerating the transition to clean transportation, and this latest move continues that trend.

In fact, the proposed ban on new gasoline or diesel engines has been in the works for some time; just under two years ago California Governor Gavin Newsom signed an executive order requiring that from 2035, all new passenger cars and light trucks be zero-emissions.

Around the world, cities and countries are starting to plan for the end of the internal combustion engine. Paris, Madrid, Athens, and Mexico City have announced plans to ban the sale of new fossil fuel-powered vehicles in the next three years—a target that might be somewhat ambitious post-pandemic.
