Disabling Commercial back up beeper

Hello, to my knowledge, this is not a "factory option" - so someone would have added the beeper. In this case, you'd have to find where it is tapped into (somewhere into the wiring that shows the shift lever is in "reverse" gear" and disable it. However, if you're not experienced with this sort of thing, I'd recommend seeking guidance at a local shop near you. An experienced technician would be able to find this quickly and help. (Note that I suppose I could be incorrect about Toyota not having it as a factory item, but I highly doubt it.) https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
