Can anyone explain this?
I already had the brake, vdc, and slip lights on before this started happening because I am currently working on a soft brake pedal issue.
The abs light would come on if I really got into the gas like from a stop. Whenever the abs light came on my radio would go out. Eventually my radio just shut off all together.
I pulled a p1211 code from my ultragauge which is the abs control unit.
Whatever this issue is also draining my battery, even while the truck is running. I could see that my ultragauge was slowly using less power throughout the day. (usually pulls around 12v, when I got home it was only using just under 8v) By the time I got home my radio was off, dash lights dim, windows and wipers barely moved, and the truck had a severe lack of power.
I have a feeling it could be a short with that control unit yes?
Is my alternator just getting weak?
Battery not holding the charge it needs?
I have a feeling this problem was starting before I started working on my brakes because while the truck was sitting for a few weeks, I would go in it every so often and the lights were getting dimmer and dimmer until the battery was finally dead.
I just wanted to get your guys insight and if there is any other possible causes I may have missed.
Sorry for being longwinded.
