After a fuse is replaced
If the lights do not turn on even after the fuse has been replaced, a bulb may need replacement. (→P. 573)
If the replaced fuse blows again, have the vehicle inspected by your Toyota dealer.
If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.

I got it back and the P on the dashboard which means park not parking brake will not go off. It’s killing my battery at night so I am pulling the positive off the battery terminal. Can anyone help please

Las luces del techo no funcionan ni las de la puertas y el reloj cada vez que se apaga el vehículo cuando se vuelve a encender el reloj aparece nuevamente a la 1:00.

Can anyone tell me which is the fuse for the daytime running light? (DRL)

~Kurt 12-09-2021
Got a 2021 Tundra and with lots of effort finally located the inside the cab fuse box...You would have to be a Houdini or a contortionist if you would ever want to attempt to change a fuse in that box. I have never seen a fuse box in a more difficult spot as this one. The under the hood one is easy and no problem. Go figure.

is there a fuse for the body control module?

~Ray 19-12-2021
I have a 2018 Toyota Tundra CrewMax with Auto High-beam switch. All of a sudden the high-beams quite working with the high-beam switch on or off. The only way I can activate the high-beams is to pull on the switch and hold it. They were working then all at once the quite. Apparently there is separate high-beam fuses so I wouldn't think both sides blew at the same time? Possible switch issue?

2010 4.6L dash/inst. lights only work in acc. position not in on position. thanks.

~Kent 01-12-2022
Which relay under the hood would be the second or third source of power for the driver’s master window control door switch if the fuse under the dash is good?

~jl 15-12-2022
eric = replace the parking breake light control switch, it could be bent out or is grounding out on the side support bracket.

~Geoff 05-07-2023
I have a 2014 tundra and had to replace the stereo head unit with after market. Lately my battery is draining over a 3-4 day period. When I pull the ACC fuse the battery does not drain. Besides the stereo is there anything else that might cause this drain?

~Ray 14-12-2023
Can anyone tell me what fuse is the ignition fuse under the cab fuse box. I ran some led light scrip, and need them to come on when I start the truck. everyone that I check the light came on when I put the wire around the fuse and plug it back in.

~Ramon 24-02-2024
2017 Tundra CM. Replaces all O2 sensors and I cleared the check engine light. After about 50 miles I got a P0157 O2 sensor low voltage bank 2 sensor 2. I'm looking for the O2 heat element fuse. Does anyone know where it is at?

2017 tundra sr5 came with an add on accessory ld300 led strip drl running lights installed at southeast toyota distributor plus in Jacksonville fl. they shorted out a new set of led headlights so I disconnected the transponder mentioned above and unplugged the drls which are on the body not inside the headlights and am wondering if there is something else in the fuses. I always thought my truck was all halogen but found out they have that add on feature that hardly worked. Does anyone han ve an idea what else is hooked to them? Thanks, Gumba in Satellite Bch. Fl.
