How To Pull Mazda OBD1 Codes Without a Scanner

[@2910mack]

its been years i have been looking for this information, thank you so much

[@ratimus2000]

Hi. I presume you had resistors in the led wires, what value please? Thanks.

[@gloumer7702]

This method works for engine codes, but not for a flashing airbag light. Any idea how to diagnose the airbag fault code?

[@Mawsheng622]

感謝！老車真的需要更多的愛來照顧！

[@shanerichards2367]

Great video where do I find the flash codes? What website are you cross referencing the flashes with.

@@lalim923 yes it worked but mine is throwing out a code of (21 16 ) 2002 Mazda 323. On the list there is no 21 or 16 . Is my car throwing out a 4 digit code?

[@lalim923]

4 digit code only can decoded by using handheld scanner , the 2 digit code is correct but for the code 21 not available in the Mazda OBD1 engine code library. Code = Memory = Circuit Diagnosed 02 = Yes = 'NE2' crankshaft position sensor 03 = Yes = 'G' camshaft position sensor 04 = Yes = 'NE1' camshaft/crankshaft position sensor 05 = Yes = Knock sensor 08 = Yes = Volume Air Flow sensor (VAF) 09 = Yes = Coolant temperature sensor (CTS) 10 = Yes = Intake air temperature sensor (IAT) 12 = Yes = Throttle position sensor (TPS) 14 = Yes = Barometric pressure sensor 15 = Yes = LHO2S inactivation error 16 = Yes = Exhaust gas recirculation (EGR) system 17 = Yes = LHO2S inversion error 23 = Yes = RHO2S inactivation error 24 = Yes = RHO2S inversion error 25 = Yes = Fuel pressure regulator control solenoid 26 = No = Canister purge solenoid 28 = No = EGR vacuum solenoid 29 = No = EGR vent solenoid 34 = No = Idle air control (IAC) solenoid 41 = No = VRIS #1 solenoid 46 = No = VRIS #2 solenoid 67 = No = LFAN relay (1993 only) 69 = Yes = ECTF sensor (1993 only)

Hi I don’t have TAT pin , how can i diagnostic transmission??

[@mariostanko21]

Way this dont work in my 323f ba, 1,5.95 yr,? I turnir wire in dijagnostic konektor and led, and no signal. Please help mi. Thanks.

what kind of connector does a japanese domestic model mazda 626 capella use?

[@lalim923]

Mostly Mazda 626 using J850bus+, if not work , try Iso9141-2 K-Line

How do u erase error codes stored in the computet after the car is fixed?

[@lalim923]

Removes negative terminal of the car battery. Depressed brake for 10 seconds will reset car ecu including error code.

For US MECS-II which pin is the BUS + line and which other pin is the BUS -ve line?

Thank you so much for sharing this knowledge. I'm going to do this mod so make trouble shooting electronic faults so much easier.

What about airbag (srs) codes? where can i find the flashes meaning for airbag faults?

[@lalim923]

Hi, In the description have the code for airbag.

[@jakeboynz]

Great video... Thankyou!! Did you just make the led tester with just any LED & wires?

[@lalim923]

Yes, correct

[@tomster7574]

@@lalim923 can you use a normal lightbulb from tester?

[@alnatural100mejor2]

No es recomndable , porque estarias pasando mucho voltaje al pin de comunicación ( FEN)del Obd1. Puedes usar una lámpara lógica. Y si usas un LED creo que debería colocar una resistencia de 100 Ohmnios en la pata positiva del led para que no termine quemandose. ​@@tomster7574

Please how can i get the software to read the codes

Hi, my mazda doesn't have a fen terminal on obd port, can you help me to find the way to connect a led to find de error code? Thanks

[@lalim923]

Your Mazda 626 car have European (EU MECS-II 1993-2002) Diagnostic Connector, It does not have the FEN pin. Only (US MECS-II 1993-1995) Diagnostic Connector has the FEN pin. You can find the fault code using ELM327 , BUS+ and BUS- is are the communication pins, check out my other video. Mazda OBD1 check engine fault code using ELM327 kzbin.info/www/bejne/epunZISmoN2JsJo

My Mazda protege year 2000 is US MECS-II. Strange
