FAQ
Question: My car OBD2 scanner shows a “Bad Adapter,” what is the problem?
Answer: This sign is normally indicated when the adapter recognizes commands during ECU initialization. This is simply a warning. As a matter of fact, car scanners don’t limit any functions. However, it is vital to know that a bad adapter could lead to some serious issues.
Question: Is my car OBD2 compliant?
Answer: This is an easy thing to determine. For cars built from the 1st of January 1996, it is mandatory for them to be OBD2 compliant or meet the OBD2 standards. Many manufacturers started to incorporate the OBD II system in their vehicles in 1994. But some car models were not 100 percent compliant.
What is the OBD2 port, and what is it used for?
Answer: OBD2 is the second set of standards and practices of the Onboard diagnostics system. This system was first created in the USA to ensure that all vehicles passed the emission standards and requirements for maintaining vehicles for extended periods of time. To ensure every manufacturer followed these practices, the law required that sensors should measure engine performance and the pollution level. In the beginning, every manufacturer created their personal systems and signals, but after 1996, all the manufacturers followed certain standards.
