I get the service stability system and had first time, car like braked a little on the front passenger side and it pulled me into side lane, but for a sec or two. I read OSBD codes on my car thru navigation screen. EBC Codes:C1282, C1284, C1287, C1288
PHN Codes:U1301, U1500, B2470, U 1088.
MSM Codes.
But I read online and sounds like the C1282-8 are causing issue.
Someone had brushed by the possibility of a brake sensor. I am getting ready to replace brake pads this weekend.
Any info on this, You are a great resource. Are parts available, is it easy to replace, plug and play kinda of thing or do I need special tools or machines to synch or whatever? And maybe a price range I could be looking at. Any and all expertise would be greatly appreciated. Thank you for your time.

This is a yaw rate sensor problem where it ihas malfunctioned and is effecting the abs as well as steering sensors. This has to be checked by a pro because it can be a short or open in system or a bad yaw rate sensor and or a abs module. Because of the malfunction it is applying the right side first because of the yaw malfunction. Have pro diagnose it with a scanner as soon as youcan

Just because you replace it doesn't meant it will fix the code it can be a bad abs unit and or a short. And it may have to be installed with a scanner making it work for your system. No you shouldn't need to disconnect battery

He is probably rigt I that respect t so he 's saying ot not pay attention to it. I'm sure you can find these rebuilt at an auto parts which may be the route you have to go an dthen have it programmed in.
