Default ABS light on?

Anybody know what the ABS light means on a 05 sti? The manual is not very clear. Could it be the front pads being to low?

It's not worn pads. Check the ABS fuse. If it's not that get it looked into professionally.

I check to see if there were ECU codes and none came up.. Also checked the fuse, It looks good. The front pads are worn and squeaking, so there is no sensor that would go off if they were worn?

No one can tell you unless it is diagnosed. No a normal scan tool can not pull codes. You will need one that can.

It means there is a fault in the system. If the fuse looks good, it could be pretty much anything from a malfunctioning sensor to a broken wire.

As for your worn and squeaking pads, if they are close to worn out, do the job now before it gets much more expensive.

I had this light come on when some ice had built up in between the pad and disc. Maybe somethin is lodged in there? Hopefully its not more serious...

It means something is wrong with your ABS (d'oh!).
More specifically, the ABS controller has detected a problem and set a trouble code, much the same as the ECU will do with an engine/sensor issue. To read ABS codes requires either a scanner which only a dealer will have, a standard OBDII scanner can only connect to the ECU and not to the ABS controller.

My ABS light came on when I was crusin up in the hills in some thick snow. I got stuck and had to rock the car out of it and then just mash the gas, snow built up in the sensor and the light came on. Once I got down to dry pavement and got my tires spinning it went off after a while. You been doing any snow/dirt driving recently?
