The ABS light went on last Saturday, then when the car was stopped, the Nippon hydrolic unit in the front left of the engine compartment kept buzzing. I left the car out and the buzzing stopped whent the battery ran dead. I tried disabling by pulling the 2 fuses which claimed to have something to do with ABS, but that didn't stop it.
Anyway, I charge the battery up all day on Sunday, then took the car to the shop on Monday. ABS worked fine, no light, checked out fine, and so did the battery. Subaru mechanic suggested that sometimes when voltage falls below 12 the ABS will act out. Never happened before in 10 years of ownership.
Everything worked fine until this morning (another Saturday, of course) when the light went on and the buzzing started again. I pulled it in the garage and this time disconnected the battery, which stopped the buzzing. After awhile I hooked up the battery and there's no buzzing, so I'm topping it off and we'll see.
We did get 14 inches of snow this week, and the Sub has been sitting out (about 5 avbove zero this morning) and there was a ton of snow in the wheel wells this morning.
Has anyone run in to this issue?
Any ideas on the source of the problem or a fix?
