Been looking around on this thread for a while, has anyone successfully found an AFM disabler for the OBD2 port or are there any programmers for this motor that are reputable yet? 2023 LT
Noticed my 2011 5.3 was at times as low as 12.5 volts and as high as 14.5 volts at the gage while on the throughway at speeds of 65 and more than a four hour drive.The battery is reading 12 volts why I checked with a multi meter the next day.From what I'm reading this is normal operating for the charging system yes?
I ran a code reader and there are no codes or pending codes.
