Hello, I have a 1996 OBD2 1UZ in a Nissan 240sx. Ive got the thing up and running and id like to pull the codes. I cant seem to find any information about pulling codes on an OBD2 without using a scan tool. Is there a way to do this without a scan tool? So Far i have tried grounding the T1 wire (Pin #5 on the 16 Pin connector[red/black wire]) hoping that it would flash the codes out on the check engine light. but the check engine light just stayed illuminated. Would one of these 22 pin adapters work with the diagnostic port on the engine to pull the codes..? Any ideas?? Thanks in advance!
