    B1484 ABS code

    I have B1484 code w/ABS light with the brake light on. It lasted a short time and went off. This has happened 3 times over 2 fays.
    This is my 2004 silver with just under 200,000 miles.
    Has anybody had this?
    What did you do to fix? I read it could be Alternator needing replacement?

    My Silver 04' has been doing the same thing recently for the past week with the ABS/BRAKE lights on. Haven't scanned it for what specific code its giving me. They turn off every couple miles too.

    You need a ABS scanner to read the code.

    After dealing with this for 7+ months, I decided to take the electronics apart from the ABS pump.
    I did replace the brake switch 6 months ago. The lights stayed on.,
    You need to remove 6 screws to separate the electronics from the pump.
    First, a GM ABS unit will not work in a Marauder. It is not compatible. Any replacement needs to be programmed in order to work.
    After seperation, I spayed all the electronics (2 parts) with cleaner. Then I put the unit back together.
    Then I had the light re-set and cleared.
    So far, the lights have stayed off.
