Hey, for a 2008 Smart Fortwo, while driving, the ABS and triangle w/ exclamation point lights will turn on and off, then on and off again about 15 minutes each time. When the lights are off (ABS functioning/working/turned on ) and i press the brake, i feel a locking on the wheels, like a skipping sensation. And obviously when the ABS/Triangle w/ exclamation point Lights turns off (ABS shut off) i have no problem, no skipping feeling when i press the brakes (i know its because the ABS is shut off and not locking the wheels). My Questions are these. When the Lights go on, can i grab an OBD2 scanner and get a code for the ABS? or will it not show up? Will the OBD2, pinpoint where the problem might be? Such as which sensor etc? Also, can a faulty Tire Pressure Sensor cause the ABS to activate/deactivate like that? I had the tire changed at a "Professional" shop: STS, they couldn't find a sensor and i think they "rigged" it or something. About a month later my ABS problems start to appear. I also think the snow and cold had something to do with it. Is there any special procedure i should do, anything i should be aware of before doing some basic ABS diagnostics/troubleshooting?
