My car was idle for more than 3 months. I jumped the car using another car. Car started however it was making loud horn so entered the code. Loud noise was not turning off. I went ahead and remove the fuse that controls the horn. I jumped the car again, now I have TCS warning sign and can not shift the gear to drive or reverse. Car runs in idle mode and when i open the car it makes the warning alarm as if someone is stealing the car. Since i removed the fuse it does not make noise.
