This noise happens when im in accessory mode and while the engine is on. It affects my calls as the person im talking to can hear the noise on their end. Does anyone know where its coming from and how to fix? Tried unplugging the dcm fuse but no luck.
 
No go for me. Stupid work. YouTube? :)

Sounds like the EVAP purge system. After my Toyotas are off sometimes they'll randomly make that sound for a few minutes.

Toyota EVAP basics

Diagnosing and successfully repairing evaporative emissions, or EVAP, system codes can be a challenge. Leak criterion has gotten smaller, so even a pinhole in a line can be enough...

Is this sound on all the time when in Accessory mode or while the engine is on? What year is your Tacoma?

All the time as frequently or 24/7?

There was a fuel pump recall. Check to see if your VIN is affected. Also check the gas cap. Make sure it's clicked on well. If it's a leak or malfunction, it might be triggering the EVAP to keep trying to pressurize.

That's what I think it is. I'd say let the dealer take care of it.
