Mazda All Trouble Codes and Fixes
What models does the Mazda error catalog fit?
Mazda, like all cars produced after 1996, supports the OBD-II format. Here is information on some Mazda models: 2, 3, 5, 6, CX-3, CX-30, CX-5, CX-7, CX-9, MPV, MX-3, Premacy, RX-8, Tribute. Mazda models produced before 1996 may not support OBD 2, as this standard became required for new cars only since 1996 in some countries.
