P305F CHEVY MALIBU CHECK ENGINE LIGHT EASY FIX

This video shows how I repaired a P305F code on a 2015 Chevy Malibu. This repair also applies to other Chevy Malibu’s, Chevrolet, and GMC’s with the active battery management system. This is not the only fix for this code. Comment below, if you would like to know more.

So I changed both batteries and also the battery module and nothing and at the end it was Fuse #18 battery isolator. Is locate it under the hood fuse box next to the main battery open it and replace fuse 18 you can use the fuse at spot 57 which is a spare.

I’m sorry to hear you’re still having trouble. Perhaps have your alternator tested

Dual battery control module.

Battery module. Check the easy stuff first like fuses
