FAQs

How do I tell if my car is OBD1 or OBD2?

When your car’s check engine light comes on, you should be able to diagnose it using a scanner. But how do you tell whether to use an OBD1 or OBD2 scanner? To start with, OBD1 supports only manufacturer-specific vehicles, while OBD2 is universal. OBD1 scanners work on cars made before 1996, while OBD2 work on cars made after 1996. OBD1 scan tools can only be connected via an OBD port, while OBD2 scanners can be connected via an OBD port and wireless connection. In terms of accuracy, OBD2 scanners are more accurate than OBD1 scan tools.

OBD1 vs. OBD2: What are the differences?

Can I use OBD1 on even the latest vehicle makes and models?

No, you can’t. As stated earlier, OBD1 scanners worked on most vehicles manufactured between 1991 and 1995. Therefore, if your car is ancient or made after 1996, this tool cannot read or erase errors in your vehicle. Nonetheless, some scanners come with both OBD1 and OBD2 functions. The challenge is that you will only apply OBD1 to diagnose specific cars, while the OBD2 feature can be used for all vehicles as long as they are compatible.
