My buddy has a 1995 Z28. He purchased a scanner for obd2 and it did not work but he has the obd 2 diagnostic connector under the dash. does he have an obd1 computer or obd2? what does he need to scan for diagnostic stuff for his car (cable and program)? thanks

 

'96's are OBD-II
The generic obd scanner works on them & newer.

 

His 95 is an OBD1 with an OBD2 connector. Yes it's stupid but thats GM for you.

 

does he need an odb1 cable to run diangnostics? or an obd2 cable with some adapter. thanks

 

the adapter must be OBD2, but the software must be OBD1.

the reason i ask is because i have on obd2 connector and freescan and it didnt make a connection with his vehicle. Any other helpful info. thanks
