Sonar light keeps blinking
 

When i turn on the car, the sonar light keeps blinking nonstop, when i press the switch the light goes on and stays on without blinking, if i press it again, the light starts to blink again non stop.
Anyone has experienced this before?? What should i do?? Any way to do a diagnostic?? I put the scanner and it said no fault code.

Thanks in advance.

Did you hit something or are they something on them? Try unplugging battery for 30 mins

I did not hit anything but i bought with the sonar not working and doing like this
Is there any fuse for the front ones?? The rear are working but the front are not

I'm guessing previous owner hit something replaced bumper and didnt replace damaged sensors

I took it to the garage and put on scanning, there were no fault codes seen.
Im thinking to open the front bumper and check the sensor connection.
Just i need to know, if one sensor is defected, the others will stop working as well untill this is fixed or how the system runs?

Yeah if one sensor is bad the rest wont work. My car has a sensor thats completely ripped out and the light flashes 24/7 when you have the system on.

The sensors will keep issue until bad one is fixed. Unplug 1 at a time but if it was damaged it will be pretty obvious

just got rear ended today and the same is happening to me....i was only hit at about 5-7mph but it was strong enough to f'up the sensors.

The sonar sensors dont take much to damage them
