I own Yamaha R15 v2.0 2012 and recently it started giving me the error when cold start. The red light will turn on and stays for couple of minutes before disappearing. The bike starts normally and even I rode it during when the red light was on without any problem. Once the light is off it doesn't matter how many times I start or stop the bike, it never turned on. It only reoccur when the engine is cold. Some time it blinks the error 46.
I have checked the battery but there is no problem with it.

Kindly help.
