On this model the PCM (engine and transmission computer) control and monitor the alternator.If there is a signal issue to the PCM due to the higher ouput alternator or an over charge issue this will occur here.I have seen this before on models with PCM controlled alternators and had to reinstall the factory amperage alternator to correct this unfortunately.
The other option is to check with an auto accessory facility to see if they have any after market programming to correct this here that they can put in your vehicles PCM.
