The check engine light is on in my moms 95 2wd tacoma (fed/can 2rz-fe) I took it to oriely's and they couldnt get there code reader to work so I took it to auto zone and they said its a obd I system and they can only pull codes from obd II. so what the hell , all the info i can find says tacoma's are obd II ? The diagnostic plug has the e1 and te1 ports can I get the codes like a 22re by jumping the terminals? anyone know whats up?
