B1484 ABS code

[BLACKMARAUDER04]

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.

Unfortunately, the lights are on and off again. I will be pulling the unit for electronics repair for $99.

Dropped off the ABS for repair. Received it back 2 days later.
Re-installed unit. All lights are off and in working condition.

This same issue with ABS and Brake Light on is very common with GM trucks 1999-2007. Solder joints on the computer board on abs controller break and need to be resoldered.

Correct! The repair person also replaces some of the items on the board also.
