I had the A/C looked at today. They claim the A/C control panel on the dashboard is defective! They're ordering the part & hope to have it done tomorrow. I mentioned the TSB - they said they'd look into it. More later...

thanks
I now drive around town in a 2wd Sequoia and don't regret getting the 4wd what-so-ever. In fact, I like the idea that there is one less thing to be concerned about maintaining on this huge vehicle.
If you plan on moving outside of SoCal into a region where there is more weather I would not even consider a 2wd vehicle. I have lived in SoCal all my life and don't think I will be moving so I made the right decision for me.

where you got your warranty at?
When I was shopping, I test drove a GMC Yukon 5.3 4x4 and a Denali. The Yukon has the GM AutoTrac on-demand 4WD system while the Denali as an AWD system. The difference, in my opinion, was dramatic, even in dry road conditions, to such an extent that I ponied up the extra $$ for the Denali.
Is the AWD always ingaged? I thought that the VSC was always active. And you could turn it off if needed.
Do you have to put the vehicle into 4WD or is there an Auto 4WD (the Explorer has auto 4WD). And if you put it into 4WD high isn't there more noise and more tire wear? Please give me some guidance.
Auto-4wd
4wd-High
4wd-Low
2wd
as the modes available for it.
Auto-4wd = can be used on dry pavement, provides some torque to the front axle at all times, can vary power between front and rear
4wd-high = locked 50/50 torque split and high-range gearset only for off-road/slippery conditions
4wd-low = same as 4wd-high except low-range gears
2wd = no power to the front axle all power is sent to rear axle
-mike
It sounds like I should hit the 4wd button and put it into 4WD High and drive, unless it is for an extended period of open road driving. Will I feel a big difference in the handling. Thanks for the help.
We need one of the Yoda Gurus to get the nomeclature for the sequoia to say which mode is "dry-road drivable" It may be 4wd w/o the diffy lock engaged gives you the dry-road driveable mode.

2WD
4WD High
4WD Low
4WD Low and Locked Center Differential
When in 4WD High it functions as a Full Time 4WD system. It can be run in any conditions.
To be in 4WD you must push the 4WD button. Otherwise you are in 2WD.
VSC is always engaged unless you turn it off.
#3 of 499 Sequoia, Land Cruiser and 4Runner by cliffy1 May 16, 2001 (03:59 pm)
Beginning with the 2000 model year Land Cruiser, Toyota began using a new 4WD system called ActiveTrac. This same system was incorporated into all 2001 4Runners and the new 2001 Sequoias. The same basic system has also been used in the Mercedes M Class as well as Humvees.
These systems operate in essentially the same way with a few exceptions. When engaged, you have three open differentials working for you (front, rear and center). Open differentials are extremely reliable and require very little maintenance. If you have equal traction at all 4 wheels, power is evenly divided between them all. If one wheel begins to slip, the open differentials begin to send all available power to that one wheel. Normally, this would be very bad. This is when a traction control system (TRACS) takes over. TRACS, applies brakes selectively to a slipping wheel. This braking action literally fools the differentials into sending power everywhere except the slipping wheel.
When you are in 2WD (in the Sequoia and Runner), you still have traction control working for you. Obviously, this only will send power left to right but this is better than nothing. There is one thing to be careful of in this condition. When you are in 2-wheel drive, there is a second part of the TRACS that can be hazardous if you are not paying attention. This is the engine speed limiter. This combines the braking action of TRACS with a rev limiter. Your engine speed will be cut back to 1500 to 2400 RPM. This allows for controlled forward movement but it will be slow. The danger with this is if it engages when you are trying to pull into fast moving traffic. This rev limiter only operates in the 2WD mode, so if you know you have any reduced traction, make sure you are in 4WD.
On all three vehicles, you have the option of locking the center differential. It is rare that anybody would ever need to do this. On the Land Cruiser and 4Runner, this is accomplished by pushing a button on your dash. On the Sequoia, you shift into 4 wheel low and shift the transmission into L. This turns off the TRACS computer and the VSC system. The vehicle is now in a conventional 4WD mode. All 4x4 Toyota trucks have operated in this condition. You should not ever use this mode on dry pavement as you will damage the drive system and tires.
The other part of this system is the VSC or vehicle skid control. VSC will selectively apply brakes and throttle to prevent understeer or oversteer. It works in both 2 and 4 wheel drive. This is a rather amazing system and does an incredible job of giving the driver control of the vehicle. Understeer is responsible for a large number of SUV rollovers and oversteer is very common on icy surfaces. The Sequoia will allow you to turn off the VSC but only when you are in 4WD. The only reason to turn this off is if you are off road and want to be able to slide sideways. On the Runner and Land Cruiser, the VSC and TRACS are disabled when you lock the center differential.
The Land Cruiser is always in the 4WD mode. The 4Runner and Sequoia can be used in either 4WD or 2WD. It is safe to leave either in the 4WD mode at all times. You will lose a bit of fuel economy, but will handle better. Unexpected loose gravel and slippery surfaces will not be a problem.
To engage the 4WD system on the Runner and Sequoia, press the button. The green and amber lights will flash on you dash. While it is flashing, the system has not fully engaged and you should avoid sharp corners at this time. If you are accelerating up a hill, these lights will continue to flash. If this happens, take your foot off the gas for a moment and tap the brake. This gives the differential a chance to engage fully into the 4WD mode. The same procedure applies to disengaging the system.
To get into 4WD low, you must first be in 4WD. Stop the truck and place the transmission in neutral. Now, move the floor shifter forward to the low range. This takes a firm hand. This mode is only to be used to remove yourself from a very difficult situation. Once you are unstuck, shift back into the high gear range.

Meanwhile, the dealer has put me in a loaner (Sienna) for free.
Also, the dealer said to always have the VSC activated and don't mess with the floor shifter because it should always be in high range. Use it in low range when you are traveling under 15MPH in snow or muddy conditions.
Please provide your input.
Thanks

Somebody else asked about pricing. The price that was quoted is very good, although any dealer could match that if you ask. Just make sure you are looking apples to apples.
You are correct in that the Sequoia cannot lock the center diff in 4WD High.
-mike
I thought I read in my 2001 manual that the Sequoia should not exceed 65 in 4wd. Thanks for the info.
Next winter, (#3 for the Sequoia) I'll just leave it in 4wd, snow or not!
Now up to 45k on the odo. Only have had one problem, (except that mail box of my neighbor that jumped out in the road...) Catalytic Converter replaced. Some folks have suggested it was because I drive the vehicle till the gas warniing light comes on. They have suggested that this extreme low fuel level consistently over time causes damage.
Thoughts?

Thanks,
Conrad007...
I had this happen on a Land Cruiser a couple of years ago. The problem? A broken spark plug. I'm not kidding. It came like that from the factory.
Anyone with a 2001 have the VSC replaced with the less sensitive 2002 version?
Thanks in advance.
Has anyone have success with one of those shops that custom fit leather wrap? I did a search on google and found several shops whose results "looked similar" to factory for around $400.
Any other reasonably priced options?
Lastly I'm concerned about the cost of having someone pull the wheel and reinstall it given the airbag and so forth.
Thanks for your input.
in the garage and couldn't figure out where it was coming from. It almost sounded like a cricket quietly chirping somewhere once a second or so. I finally tracked it down to the gas cap on the Sequoia, air was leaking in or out due to the pressure differential. The cap was on plenty tight, and removing it released the pressure (I think vapors came out) and that was the end of the noise. The gas tank is about 2/3 full. The wife says "Oh ya I've been hearing that a lot in the garage, I thought it was the garage door opener" Anyone else ever experience this? Is the gas cap bad, or do I have a fuel system problem?
I can almost guarantee that it has something to do with the emissions system. It is probably normal, but if you are concerned, have your dealer look at it.
We have an appointment for tomorrow and will pick up a rental at our expense (Toyota won't pay until they determine what the problem is)
So far our dealer service has been fairly good, of course they've had to do very little beyond "free" oil changes and the decidedly not free 15,000 mile service. We'll see how they respond to this problem. I don't plan on mentioning the TSB or my readings in this forum until I hear what the service guy says. I'll let you know.
6 year, 100,000 miles for $930
7 year, 100,000 miles for $1090
Thanks for your help.
Platinum prices: The best I've come up with here in the Seattle area is $1180 for 7/100K with 0 deductible for an '01 Limited 4x4 with 11K miles on it.
Check this out fellow Sequoians: July/August edition of Truck Trend. Article on long term wrap-up of 2001 Sequoia. Very postitive as you would expect. Some interesting information on what they believe is in the works......quoted from the article,
"What's Next for Sequoia?
Although not scheduled for a freshening until '04 and a remodel in '06, the new HD Tundra 5.4L
V-8 could make its way into a bigger/longer Sequoia by next model. Look for GMC Yukon Denali-type Sequoia, as Toyota has been watching what GM has been doing with its own large SUV's. The possibility also exists that Lexus could get the version first."
