Hello all I just got my car scanned. I have been having BCI light turn on 10 seconds after I start driving since last two weeks I was driving fine it’s giving me a triangle and a small car sign on the left top of the odometer. These two codes are pulled. Any idea what to do it’s annnoying me now thanks in advance

who scanned your car? dealer or a friend?

those codes are related to the nanny features, aka driver assistance features. can you use any of the cruise settings? if not, adaptive cruise control is likely resulting from your sensor and perhaps your camera(s). one of your front sensor / wiring harness is bad. Not a reliable connection to the canbus. possible one of your cameras is not calibrated. Wasd your car in a recent accident or have you done any mods to any part of the car? wire harness?
ive attached the driver assistance service manual. if you have a friend smoking this over, and they are mechanically inclined, have them look at the attached pdf. its for a 2016 maxima but should give some info on the alerts.

No mods no crash. Front back side mirror cameras work perfect, I have actually not tried cruise control as there was never any need for it, but will do tonight. Try starting the car this morning and it would not start so I thought after eating a lot of information on this forums that it could be the brake switch and replaced OEM one , and jumpstarted the car charge the battery everything is OK but that BCI light is still on 10 seconds into driving.
