Should you short them out while car if off then turn on? Then turn it off before removing the short wire?

[timjnbaptiste]

Where can I get the diagnosis codes lost to know what each number flashed means

What if the car won't start, will it still show 'codes' ? I put in anew distributer and it fired right up. 10 minutes it dyed, restart a couple times then not. Next day, started - dyed, , two times. Where do I find list of 'Codes' ?

Hey i swaped my car with same engine but it doesnt have a check engine light since the engine was swaped from 1.3 carburater to 4afe so how can i put a check engine light so i can se the codes plz help 😊

[RandoKing]

2 Questions, 1: if I have a wire jumping the diagnostic pins but no o/d light blinking did I do something wrong?, 2: when I jump the pins CEL is the only thing that's blinking, not in Morse code fashion, just constantly blinking. any help would be great

What is the diagnosis box for? I have 93 toy corolla and don't know what it for. I opened box up and it has a white goo all over the open holes.
