All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections .
OBD-II is an improvement over OBD-I in both capability and standardization.

It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each.

When two pins on the ALDL are jumped, the light would flash the codes, for instance (blink) (pause) (blink) (blink) for code 12. Some manufacturers, such as Honda, retained this feature even after OBDII.
