94 is OBD I and you can use a scanner like a tech 1 or 2 on it. OR use a paper clip for engine and ABS codes. No trans codes.
Go to
formatting link
look at the picture of the ALDL connector. Pin A is a ground
Ground pin B for ENGINE codes, key on engine off.
Ground pin H for ABS codes then watch ABS light and count the flashes.
