How do you pull codes from a 1993 Mazda b2200?

To pull diagnostic trouble codes (DTCs) from a 1993 Mazda B2200, you need to locate the diagnostic connector, typically found under the dashboard near the driver's side. Use a jumper wire to connect terminals TE1 and E1 in the diagnostic connector, then turn the ignition key to the "On" position without starting the engine. The check engine light will flash, displaying the codes in a series of long and short flashes. Count the flashes to determine the specific trouble codes.
