because 96+ cars are OBD2 and 95 H22 is OBD1 and 3J0(p13) ECU is OBD1 too...
So it makes your OBD2 connector useless because you can't read OBD1 ECU through OBD2 connector, so you just have to go old fashion way, like for any other OBD1 ECU, jump 2pin blue connector next to glove box, turn ignition on and count flushes from "check engine" light, long flushes is 10 and short is 1(2long + 3short=code23 or whatever you got) it will be 3-5sec(dont remember) pause between codes
