You can read the codes yourself on a 95 ls with a volt meter. I dont have the info with me, but you could probably find it on some Diamante forums. I have done it before. You just connect the clips to two pins on the obd connector and then read the meter sweeps like morse code. Some mitsu forum out there should be able to tell you which pins and the code translation.
