Check engine fault codes

TextHello.
I have 730 V8 -93. No Bordcomputer only Digital clock and thermometer.
Should i get Check engine light codes if I switch ignition on and pressing accelerate pedal to the floor 5 times with in 5 second?
I don't get them.
What is wrong or damaged?

It´s normal, nothing defect.
Not all engines are working with the lightcode.
You can only read the Checksum with BMW DIS or Carsoft .
