Hello: The RFA stands for the Key Fob That you use to lock?unlock your doors. RFA stands for Remote Function Actuator.. Replace the battery. Go to Auto Zone and they should have the battery and probably not charge you to replace it.

RFA1 BATTERY LOW


The message stands for Remote Function Actuation (RFA) battery low. This in more simple terms means that the battery in your remote for the door locks is getting low and should be replaced soon.

Just replace the battery in you keyfob remote.

Excessive black exhaust on 2003 GMC Sierra Duramax Diesel.


This is what i would try (cheapest first) redexe/wyyns
injector cleaner,double dose,then i have put 1gal gas in 10gal diesel to increase burn temp (you may encounter a hot start problem temporarilly)then if still smoking, get a compresion check on the engine(this will tell you volumes)
by the way the NATO tanks put in 1/3 gas in diesel to stop it freezing in arctic conditions.any more than 1/3 can result in problems.
