Stands for On Board Diagnostics its not only a honda thing but..


Summary:

1. OBD1 is connected to the console of a car, while OBD2 is remotely connected to the vehicle.

2. OBD1 was used during the earlier years of the car manufacturing industry, while OBD2 was only introduced in car models produced in the early 1990′s.

3. OBD1 has good diagnostic capabilities, while OBD2 has better signalling protocols and messaging formats.

96+ cars all have a OBD2 port easily accessible under or near the drivers foot well. Its a current emissions standard
