so far the only answer is to pay the dearler $35 dollars and wait 45 min. while they clear the memory of the radio. Personally, that sounds like unpluging something until the memory is erased, but as to what I am not sure.
There is a magic code for 93' models only (each year has own code), "0532" and you enter it in during the following sequence.
1 disconnect power for at least 30 sec. 2 put key in ign. and turn to aux. power or whatever setting allows the radio to play. 3. if locked out you see Err. on the screen. 4. press Scan key 5. press am/fm key 6. press Auto M key 7 press Tune up arrow 8. Enter code 0532 9. press Scan and Auto M keys same time until radio restores (5-10 sec)
No, the 1993 Mazda Protege DX does not have an airbag. The vehicle does have a passive restraints system and is extremely reliable.
1) Just start your car with the coded key 2) Pull the battery cable but do not leave it off too long only a few short seconds. (if you leave it off too long the pcm will forget the saved key code then you will need your pcm flashed in order to work with your key again) 3)Bypass the antithief by removing the antitheft wirers. The antitheft system only cuts power to the starter. run your own wiring to the ignition switch to bypass the antitheft.
YOu need to blead the system .. then it should require no adjusting
Use the key fob. Lock then unlock
For my Mazda I use 10w-30
Follow + battery cable should connect to solenoid
you will have to get from Mazda or buy a used one
