On cars from about 1980 to 1996 they have ON BOARD DIAGNOISTICS 1 which is not as effocoent as OBD11. I am not sure how you get the codes from the OBD1 on this perticular car other than a scanner which auto zone will read for free. On the American cars you ground the "A" and"B" terminals in the ALDL connector and count the flashes of the check engine light.
