I did the paper clip trick on the obd1 port and it went into the normal 1 1-2 blink diagnostics startup
Then after the 3 times with that it did
1 1-2 again 3 times continuously after the initial 3 times … I wasn’t sure but Can there be a real legit sel code 12 or am I just seeing the diagnostic setup repeating over and over for some specific reason .
This doesn’t pertain to a gmt400 but my 91 s10 which all the same obd1 methods of reading codes
