i looked up the discription but dont understand it. Generator L-Terminal Circuit ECM, PCM thats what it says.

 

It means that your control or signal wires are not seeing what they need to. I cant remember off the top of my head but i think thats the wire that tells the alternator to increase or decrease. So you need to check the wiring @ the alternator and check alternator output. It could be a bad alternator, wiring , or even an ECM. most likely the alternator or wiring though.

 

You are right i made sure all the wiring was put in and i forgot to plug one of the sensors plugged in and no cel now +rep to you my friend
