@DoCoR69 Go get a part called a brake switch or a brake light switch, should be able to get it at any auto parts store for like $20. Then google how to replace it, it's a simple 10min job. 95% of those BAS/ASR errors are caused by this part. Good luck!
@cmigneco lol This is so old. I forgot I used to this Mustangs were such hot shit. My comment was so ignorant and fanboyish. I've since realized the majority of american "performance" cars are really quite bland. I've since found european cars to just be so much more fun.
lol I had forgotten about this. I grew up and stopped playing with toy... I mean Mustangs a long time ago.
