  1. Highlander hybrid mpg thread

    Highlander 1st Gen - Hybrid (XU20/2005-2007)
    Once warmed up the the Hihi gets better mileage. So if you do predominantly short trips in cold weather, that is certainly not the hihi thing. Highway mileage is also not a major advantage for the hihi (hot or cold). But long trips in city driving, even in cold, that is the hihi's thing. (That's...
  2. 12v Battery and Failure Mitigating Strategies

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    Note that when the hatch is open, even if the vanity light is off, it wakes up the computer, which draws something like 2Amps. Same with the doors.
  3. Brake malfunction check VSC system

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    The VSC activates if you skid, or need antilock barking etc, even without rain. If there is a real problem with this system, this is a likely time for this system to realize it and flag it with a light. That said, especially if the mechanic thinks the car is ok, random flags sometimes do get...
  4. Brake malfunction check VSC system

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    If your brakes break when you brake then they are broken. It is unlikely that the break was caused by the act of braking hard. However, the VSC system covers traction and stability control, and would activate, especially in rain, if you tried to brake fast enough to cause a slip or skid...
  5. How to reset Check engine and VSC warning lights

    Highlander Hybrid
    Alas, the procedures I posted are specifically for Toyota 2006 Highlander Hybrid. While they may work on some other model years, or even in some cases on other models, they more probably will not. Sorry. As always driving with a VSC issue or a VSC Light on is dangerous.
  6. 12v Battery and Failure Mitigating Strategies

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    Any after market bat will do. I used a wallmart one. Change it quick before you get frustrated with your car.
  7. 12v Battery and Failure Mitigating Strategies

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    Note: I can do this too, but only AFTER changing my bat. Also, I went to several diligent mechanics, and it won't likely be a parasitic drain, my OEM bat passed EVERY test, the diligent mechanic refused to change it (didn't want to rip me off, very nice guy actually) but once I won the argument...
  8. AWD hack?

    Highlander 1st Gen - Hybrid (XU20/2005-2007)
    I believe there are hacks for turning off the VSC/Track, but alas it is these systems that dictate that power be sent to the rear. As the rear wheels are 100% electric, disabling the vsc/track turns these wheels off. If you wanted to make such a hack I think you would have to send a spoofed...
  9. Check VSC, SRS, and Hybrid systems Warnings

    Highlander 1st Gen - Hybrid (XU20/2005-2007)
    You can't just look at the little blue indicator on the batery. My indicator said my batery was fine, it wasn't. In fact I had to argue with the walmart guys who replaced my battery, because the old battery passed their electrical tests too, but none-the-less my would-not-ever-start car hasn't...
  10. 12 Volt Battery Problems

    Highlander 1st Gen - Hybrid (XU20/2005-2007)
    I did in fact once jump my car using 8 "D" batteries. Can confirm this works. Also once tried 8 AA batteries as well, these are too small. Replaced my 12v bat before trying C bats, so can't say on these, have never had to jump since. (2yrs now) I think the largest load on the bat when...
  11. Kids, Carseats and Safety

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    Just to elaborate on Q1, we have two children and two aproved booster seats, so normally everything is fine, but on occasion when we find we are suddenly driving a "guest" child, we have been known to pull down the "armrest/cussion/cupholder" thing that resceses into the middle of the back of...
  12. Check VSC, SRS, and Hybrid systems Warnings

    Highlander 1st Gen - Hybrid (XU20/2005-2007)
    Some error codes will change the driving behaviour and safety level of the car, so obviously proced with caution but.. I keep a printed page with all the code reset procedures in the trunk. I would NEVER go to a mechanic until I'd tried reseting the code at least once. Not that it happens...
  13. Kids, Carseats and Safety

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    I have 2 quick questions, My children are old enough not to need child seats, but now use booster seats, soon won't need those. Q1) Can i use the rear middle pull down cussion as a booster seat? We don't do this often but we do when we suddnely end up with friends etc. Q2) My understanding...
  14. Disabling some "features"

    Highlander 2nd Generation (2008-2013)
    Have done it as rook describes, it's also in the repair manual, worked on my 06 highlander. On the rare occation when I choose not to wear my seatbelt, (usually because I'm parked toying with the computer or something) WOW is it anoying. I'm surprised they didn't attach a taser to the steering...
  15. The Official Mileage Sticky -- anything about mileage discuss it here

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    To get the best mileage: 1) The car gets poor mileage in its warm up phase. Get out of this as soon as possible. Due to a 'design flaw" or legal regulation or something, the car, at least mine, requires an aprox 10s stop after warmup, before it will leave the warm-up mode. Pulling over once...
  16. 08 Highlander Hybrid... mileage plummeting

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    This isn't really a bat thread, Check: http://www.toyotanation.com/forum/showthread.php?t=257255 but in general, the hihi is very hard on its tiny 12V bat, especially if it is sitting around parked. Personally I think the oem one isn't that good, but even regular bats are only rated 3-5yrs...
  17. 2007 HiHy Brake Calipers

    Highlander 1st Gen - Hybrid (XU20/2005-2007)
    1) Don't trust the dealers. I had a problem with the seat. Every time I braked I felt movement in the seat. Paid dealer over $100 to diagnose problem and inspect car for other problems. They said whole seat needed to be replaced. In fact, loose nut, which I tightened, no problem since. The...
  18. Airbag, VSC, and Check Hybrid System lights

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    That's kind of scary, if your head/body is in the wrong place when those go off you can be killed. Obviously that's more than a power supply problem. Posibble the technitian shorted something he shouldn't have, but also possible an 08 computer software design flaw, or some sort or wire...
  19. Airbag, VSC, and Check Hybrid System lights

    Highlander 2nd Gen - Hybrid (XU40/2008-2013)
    From what I can gather: C1241: Low Battery Positive Voltage Caused by: 1. Battery 2. Charging system 3. ABS No.1 relay 4. ABS No.2 relay 5. Wire harness or connector 6. Brake control power supply assembly 7. HV control system 8. Skid control ECU P3107:Airbag ECU Communication Circuit...

    Airbag light Airbag SRS light You must jump two pins of the OBD plug under the dash by the left knee. Use a paper clip or wire to jump TC to CG.
