Car Forum / Toyota / Toyota Cars / March 2007[Q:] do the accessory powerpoints automatically turn off after a period of time???
I have a 2007 Toyota Sequoia that I plugged a maglight rechargable flashlight into one of the accessory powerpoints located on the lower right front of the center console and left in overnight. When I returned in the morning there was not power flowing to the flashlight charger, but when I started the engine, the power came back. Does anyone know if this car is smart enough to recognize a load on the car battery and automatically turn it's self off after an amount of time as to not let the car battery die? Or is it a timer that turns its self off after a set amount of time? Toyota Corp. doesn't know for sure, and neither does my dealer. Is there anyone out there that knows for sure? Thanks Are you saying that the flashlight continued to charge after you turned off the car? But then sometime in the night the car stopped the current flow to the power point? I would find that very surprising, my instinct says that the power point is either powered all the time, or only active with the ignition in the "on" position. > I have a 2007 Toyota Sequoia that I plugged a maglight rechargable > flashlight into one of the accessory powerpoints located on the lower right [quoted text clipped - 12 lines] > > Thanks > Are you saying that the flashlight continued to charge after you > turned off the car?

The rest of the time they are off. You could come up with a nifty circuit using something like a 555 timer chip (showing my age, but these things are only 5 cents now!) that would keep an add-on power point running for X minutes, but you'll have to ask Bruce about that. I've forgotten 90% of what I knew! > Are you saying that the flashlight continued to charge after you > turned off the car?

My dad's car automatically turns on and shuts off the lights. The lights shut off after the engine is shut off and the keys removed. It's not a difficult engineering problem to automatically shut off a power point after so many minutes, either. So it may be shut off automatically either based on the draw on the battery (not hard to measure) or a fixed period of time. The power point in one of the pickups is capable of delivering 400 W. That is a draw of around 40 A (in know 40 A x 12 V = 480 W, but there is probably some lost in the DC to AC conversion). That's 1/3 of the capacity of the alternator. Another way to look at it is my notebook battery is maybe 10x smaller than a car battery. It delivers maybe 65 W for 2 H, or 130 WH. If a car battery holds 10x as much energy (1300 WH), you're going to drain the battery in less than 3 1/2 hours. So it would definitely make sense for the SUV to monitor the usage of the port or just shot it off after say an hour. You might try looking in your owner's manual. Or just go out to your truck every hour or so and see if there is power at the power point (you could, for instance, plug in the mag light you talk about).

Great car, completely sold me on Toyotas. The problem with all those newfangled conveniences is that it makes the owner forgetful or spoiled. With auto headlights, the only time I touch the headlight switch is to turn the headlights in the rain, snow, fog, etc. I went to move a friend's car and left the headlights on - oops! With automatic door closers, it is not necessary to slam the door closed, so now when I close someone else's door, I don't always use enough force for the door to close all the way. My next project is to figure out how to use the compressor under the hood to fill tires so I don't have to fire up the home compressor.  SignatureRay O (correct punctuation to reply) > My next project is to figure out how to use the compressor > under the hood to fill tires so I don't have to fire up the > home compressor. Cannot recall if I have mentioned this one here; my apologies for any repetition... Bedford (a subsidiary of Vauxhall, one of GM's UK marques) used to make (1960s on) the 4WD "Bedford 3 Ton" lorry for the British Army. One handy feature was that the pressure in its air brakes was the same as in the tyres, 75psi (IIRC); it was easy to feed the supplied pressure hose from a central air point.

That easy's. Make an adaptor for your air hose that lets you screw it into the spark plug holes. You should get about 150 psi from that. That's the compressor you're talking about, but it will work. Jeff >>> My next project is to figure out how to use the compressor >>> under the hood to fill tires so I don't have to fire up the [quoted text clipped - 13 lines] > > Jeff Filling tires from the spark plug hole is a an idea that has been around a long time, but there are a couple of problems. Not only is the fuel that is being injected into the engine flammable, it will do bad things to the inside of the tire. The other problem is that without burning the fuel that is injected into the engine, the volume of gas coming out of the spark plug hole is pretty small. It is a lot cheaper to buy a 12 volt compressor than a new aluminum head when the owner has ruined the threads by pulling on a hose.

I like things that multi--task! In the U.S., some trucks with air brakes have a similar feature and even use the air for the driver's seat suspension. I have not had to do anything with the on-board compressor, so to be honest, I don't even know where it is. I'll have to go hunting to see how it works!

[...] And what makes this approach even nicer is, the multi-tasking can extend to subsystems like that for regulating pressure, which can do double duty for brakes and tyres. Moreover, there is no point in hauling along a tyre pump, because if the air system goes AWOL so do the brakes and any notion of using the vehicle in a serious way. Therefore that bit more payload can be carried -- and there is one less d*mn thing to break/maintain/mend/buyinthefirstplace. SignatureAndrew Stephenson Yes Mark, the powerpoint stayed on after turning off the key, but a couple hours later it turned off automatically. I appreciate everyone's guessing on this one, but as I said before, I've already consulted Toyota and the operator on the phone who said they spoke with a "technician" said that it turned off with the key, so I know they are wrong. The dealer didn't know either. The luck of hitting a service tech who actually knows the answer is slim, which is why I'm opening the question up to the whole internet world. However, I would appreciate an answer from someone only if they know the answer, not if they are merely reporting back what theirs does, or venturing a guess. Thank you. > Are you saying that the flashlight continued to charge after you > turned off the car? But then sometime in the night the car stopped [quoted text clipped - 22 lines] >> >> Thanks Interesting, let us know what you find out. As Ray mentioned, my Scion tC's power windows continue to work for about 30 seconds after ignition is shut off, as long as the doors remain closed (a very handy feature). > Yes Mark, the powerpoint stayed on after turning off the key, but a couple > hours later it turned off automatically.

Toyota refers to the feature you are inquiring about as "retained power." You can check the factory service manual at www.techinfo.toyota.com for $10.00 per day. Look under the BE (Body Electrical) section to see if the 2007 Sequoia has this. Toyota's usual setup for retained power is 30 seconds, or when you open one of the doors, whichever comes first. I thought the retained power was just for the power windows and sunroof, but you can check yourself to see if the accessory outlets on your Sequoia are also retaining power. If I think of it, I'll check our Sequoia Limited to see if the outlets have retained power when I get home. In the 2007 Tundra, the retained power was extended for up to 2 hours but knowing how Toyota implements changes, I would be surprised if this change was incorporated in the Sequoia without a major changeover for the Sequoia. Another possibility is that the LED indicator does not go out right away on the charger when the power is cut off. The LED on my laptop adapter glows for a while after it is unplugged SignatureRay O (correct punctuation to reply) Ray O, that's interesting. It could be that. The power stays on for a lot longer than 30 seconds, but I'm not sure if it's more than 2 hrs or not. I'll have to experiment to see if it is a consistant amount of time, or not. Otherwise, I think it has to do with what Mike Hunter said, that it is based on a power draw. >> Yes Mark, the powerpoint stayed on after turning off the key, but a >> couple hours later it turned off automatically.

Leaving the outlet hot while there is a power draw is a very convenient setup, but I have not seen it in a Toyota yet. I checked out 2003 Sequoia last night, and the accessory outlets on the side of the center console do not retain power - it immediately turns off, so the setup is not the same as in the 2007 Sequoia. A different topic, but I think you will be very pleased with the Sequoia's traction. I drove a sample of every AWD and 4WD vehicle Toyota offered from 1978 through 1993 plus our 2003 Sequoia, and the most sure-footed and stable vehicles were the Camry All-Trac and the Sequoia. Our Sequoia has traction and stability control and the only time I have ever been able to get the stability control to even kick in is in 2WD, on a snow-covered empty lot with the steering wheel cranked all the way over and flooring it. Instead of spinning donuts, it just beeped a few times and started going in circles. I tried it in 4WD, and I couldn't get it to spin - it just went in circles. The biggest danger I can see from the Sequoia's sure-footed-ness is overconfidence and going too fast for conditions and ending up with the rest of the SUV's in the ditch. SignatureRay O (correct punctuation to reply) Some vehicles, like most late model Fords, are equipped with a sensor that detects a high amperage draw, like letting the headlamps on, when the ignition is in the off position. After a period of time it cuts power. It resets when the ignition is again turned on. Perhaps your vehicle has something similar. mike > Yes Mark, the powerpoint stayed on after turning off the key, but a couple > hours later it turned off automatically. I appreciate everyone's guessing [quoted text clipped - 8 lines] > > Thank you. Mike: This is what I think it is, since it seems to be a random amount of time that it shuts off each time. I'll experiment with some different high and low amp equipment to see if it varies.

You probably have not been in contact with the right person. It may mention that in the owners manual. You may want to try the Toyota nation web site as well. Good luck. >> I have a 2007 Toyota Sequoia that I plugged a maglight rechargable >> flashlight into one of the accessory powerpoints located on the lower [quoted text clipped - 16 lines] > owners manual.

It stays on after I shut off the ignition." I am sure that they have something abotu this in their service manuals they can look up. Jeff >I have a 2007 Toyota Sequoia that I plugged a maglight rechargable >flashlight into one of the accessory powerpoints located on the lower right [quoted text clipped - 12 lines] > > Thanks The accessory outlet are not on a timer. It is hot when the ignition switch is in the on or accessory position and off when the switch is off. AFAIK, the only circuits that are timed to stay live for a while after the ignition is turned off are for the power windows and sunroof and for the headlights. SignatureRay O (correct punctuation to reply) > I have a 2007 Toyota Sequoia that I plugged a maglight > rechargable flashlight into one of the accessory powerpoints > located on the lower right front of the center console and left > in overnight. [...] FWIW my T dealer assured me the Prius power outlet for cancertube lighters turns off with the ignition. (But haven't tested this.) T seem to like being consistent across their range of models. Why not do a controlled test? SignatureAndrew Stephenson >I have a 2007 Toyota Sequoia that I plugged a maglight rechargable >flashlight into one of the accessory powerpoints located on the lower right [quoted text clipped - 12 lines] > > Thanks The typical operation is that the power point(s) and cigarette lighter are off whenever the key is off. Some makers will keep the cigar lighter powered, and some will shut it off. My BMW turns it off, but my Bronco leaves it on. Well, I think that the final analisys is that the accy plugs do shut off on a timer. It's not within a few minutes of turning off the key, but within an hour or so, they shut off, even if there is nothing plugged into them whatsoever. The downside of that however is that you can't charge up a cell phone or rechargable flashlight etc... when the engine is off. That kind of sucks. >>I have a 2007 Toyota Sequoia that I plugged a maglight rechargable >>flashlight into one of the accessory powerpoints located on the lower [quoted text clipped - 17 lines] > powered, and some will shut it off.

I know on my Scion, if you leave the door open, after 20 minutes the interior lights turn themselves off. I don't know about the power points, though... >>>I have a 2007 Toyota Sequoia that I plugged a maglight rechargable >>>flashlight into one of the accessory powerpoints located on the lower [quoted text clipped - 17 lines] >> powered, and some will shut it off.
