300SE 1989 or similar Check engine light

The search function was not operational so I could not search archives.

Is there a way to get a CEL diagnostic code by switching the ignition key on/off several times and reading the light blinks on the dash?

Does anybody have the code sequence for the O2 sensor etc??

Thanks

1989 300SE with check engine light on.
