Pre Canbus Were Any Car Parts Coded ?

[V8RX7]

Am I right in thinking that pre canbus, car parts couldn't be coded to cars, or were there any other systems ?

Yes AFAIK parts can't be coded to a car without canbus but I wanted to check

I'm not so surprised when it appeared but by how late it appeared on some cars, it seems some didn't have it until 2008
