    "RFA 2 Battery Low" - alert from my display


    Support FSC and see no ads! - Click Here
    Today my 2003 Silverado 5.3 dashboard informed me of "RFA 2 Battery Low" which a google search suggests that my key fob remote has a low battery. And yes, I have been using my fob #2. So I switch to fob #1 (which I never use) and the alert is still there. It appears when you first turn the truck on, then goes away to whatever normal display you have set to come up.

    I'm thinking my #2 fob does need a new battery, but how to clear the alert? Just using the other fob didn't change it.

    Thanks!

    So nobody has seen this? I would think a lot of folks see this as key fobs get a few years old....

    It may not be safe to assume the battery in the #1 fob is ok, but if it is good, many of the stored fault messages take a certain number of start cycles where the fault does not occur before it will clear itself.

    On the old ODB I computers you could just unhook the battery to clear fault codes, on the ODB II computers you either have to clear them with a reader or wait for them to clear themselves.

    If fob #1 was bad I should be getting a code for that one too.

    I checked on my GM service information and well it doesnt really tell me a whole heck of a lot so my guess would be replace the battery's in both remotes, ive personally never actually seen that message but if it doesnt go away after you replace the battery's let me know and ill ask some of my other techs

    Maybe it's looking for a Battery OK condition. Replace the battery in fob #2 and use it a few times.

    Guys - I still have not been able to resolve this. I replaced the battery but it still does not work. I double-checked that the battery is good using a multi-meter and it is installed correctly. The other key fob works. I can only think there is a synchronization process I have to follow. I have other fobs for things and you usually have to push the buttons in a certain way to get it to sync back up.

    You need to hold the lock and unlock buttons down at the same time until the locks cycle. This will resynchronize the fob.

    procedure:

    Instructions for new body style trucks:

    1) Close all the vehicle doors.
    2) Insert the ignition key into the ignition lock cylinder.
    3) Press and hold the door unlock switch.
    4) While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
    5) Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
    6) Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
    7) Repeat the previous step to program up to four transmitters.
    8) Turn the igntion switch to the RUN position in order to exit the keyless entry transmitter mode.
    9) Operate the transmitter functions in order to verify correct system operation.

    I've replaced the battery in FOB #2 which now works great but the message in my 2003 Sub still won't clear. Can you check with your techs? Thanks

    I wonder if the original poster ever got this fixed.

    Wow good post, I wonder why GM didn't make step 10 hop around the truck counter-clockwise on your left leg.

    Re: "RFA 2 Battery Low" - alert from my display

    Has this issue been resolved. I just changed (3 days ago) the battery and am experiencing the same issues. I took the truck to my local dealership so they could do the 'dance on their left leg around the truck' and the comment remains in my DIC. The service tech writer commented that he had never seen this before. Any answers on getting rid of the message?
