I cannot figure out what's going on...My low beams do not work and my high beams do..I have a good battery and alternator but somwhere along the lines, it will not charge.I'm throwing code 20 and 43.. I want to if the eld was bad, will it not charge the battery?

The low beam part has me confused too.All fuses are good so is all the relays..It is grounded good.I been searching for about a week and did alot of test's i have seen.I have come up with nothing....

 

haveu tried other bulbs?? just a thought.

 

I fixed the lights..The plug with all the grounds came off...duh....!!!

It still don't help me with charging the battery.Its 12 volts reguardless if the motor is runing...Its like the alternator is not cutting on.From what i seen so far is, the ecu control's the charging system..
