On early DDEC you could hold or hit the override switch to check codes. Lets say the check engine light blinks 3 times and then it stops then blinks 2 more times. That indicates inactive code 32. If the stop engine light blinks a code that is an active code which will shut the engine down.
Check engine light blinks is an inactive code.
Stop engine light blinks is an active code.
If you lose count you can start over after it quits blinking.
