Subaru B9 Electrical/Lighting Problems

    I checked that the last tie this happened, and it was OK, but I forgot to check it again this time. I'll do that first thing in the morning...thanks for the (seemingly obvious) reminder!!!

    By a bad ground though, it could be not only on the battery side but on the other end of the ground cable where it attaches to the body of the vehicle.

  • kmartinkmartin Posts: 427
    Well, it wasn't the ground. However, after having a local service station check my battery/alternator, they think the battery is on its last leg (or volt, or amp :-). My 'Beca is 1.5 yrs old with 25k miles. I know the desert summers are hard on batteries, and they tend to die after a couple years, but this seems kind of premature. Anyone else had to replace a battery yet?

    Craig just went through a battery on his Outback XT, and he too thought this to be premature.

  • Hi,
    The light for a tire pressure problem continues to come on.
    When the tire pressure is checked they are fine.
    Does anyone have this problem?
    IF so what is the deal and can it be corected?

    I am also interested in disconnecting the seat belt indicator noise.
    It is too aggresive for me.

    Any help will be appreciated.
    I have an 07 and love it.

  • Do a search back in the main forum for seat belt or chimes. Look for Karen's site. She has detailed instructions for disconnecting the chimes. I did it without any problem. As for the tire pressure, do a search there too. I seem to recall other guys having the same problem with the tire pressure light too.

    It's on my web site, but I'll post it here, with the usual cautionary statement...hopefully the powers-that-be won't delete the post????

    Cutoff Function for Seat Belt warning chime
    (Works for the 2005-06-07 Outbacks and Legacys, too)

    Warning: I am in no way responsible for anyone’s safety...just posting this as a convenience.

    1. Turn the key to “ON” (not running).

    2. Fasten and unfasten the driver’s seat belt 20 times in 30 seconds, starting from when you actually turn on the key. (This will set the passenger seat as well).

    3. Turn the ignition on, and you should be set. It may chime 6 times at first, but then it should quit.

    4. Setting lasts until the battery is disconnected or the system is otherwise reset.

    5. If you want to do this as a temporary thing (just for one driving period), fasten/unfasten the belt 3 times in 6 seconds. The chime will reset the next time the car is started.

    It wasn't the battery, either...they checked out everything they could think of. All they did in the end was to pull the appropriate fuse and reseat it. Things are working as they should for now (radio presets, MFD display, seat belt chime settings stick, etc.). To be continued...


    PS: I checked the ground on the Fm modulator I installed as well, but it was OK. I hadn't turned it on for a few weeks just to see if that was the culprit.
  • I have a 07 Tribie 5-p Ltd with Nav sys. I noticed the GPS is an older version (04-05), anyone know how I can get an update? My dealer told me to call Subaru, but I am just wondering if anyone else here has the same wonder.
    Thanks. Paul

    Hi, Paul. Subaru replied to my email this week that they are now saying "early 2007"...see my post in the Tribeca Nav forum.

    When the update does eventually come out, is this something that will cost, or just no charge to those owning Tribeca's with Nav systems?
  • Thanks Karen. I will contact them again and see what they say now and let you know. Paul :)

    No problems with Tribecca battery (18 months 18K), but the battery went on my '03 Saab after 3 years and 40K and was replaced under warranty :) Seems like Subaru should replace your battery.

  • kmartinkmartin Posts: 427
    Turns out it was the battery after all. There was a problem with the core itself. The tech told me he thought his battery tester was not working properly last time I was in, so he sent it out for recalibration. He says it still isn't up to par, and he doesn't trust it 100%, but he finally got the reading he was looking for. He says he will complain at the tech school training this next week. So far, so good, at least for be continued :-)

    Tire pressure light comes on if there is a difference in outside temperature. Being in New England I saw the light come on the first time when the the temp went below 30F. The owners manual shows different minimum pressure for different temp.

    Home today only (off on another business trip) and need to change a head light on my 2006 B9 for my bride. Has anyone had to do this, is it a simple change that competent owners can do, can I buy the replacement bulb retail?

    Now the big question, are the blue bulbs available for the B9?

    Why blue bulbs? You do know they reduce the amount of light on the road right.

  • nhstevenhsteve Posts: 78
    No I was not aware of that, I thought the Cool Blue would lite the road better. Either way, I cannot seem to be able to get the headlight assembly our to replace the bulb. I cannot see what I am doing from behind the assembly. I suspect they make it so hard to get to in order to generate service revenue. $36,000 was not enough and now I have to pay someone to change a light bulb!

    You may have to go in from the fender well. I know on my Armada that's how you have to do it.

  • nhstevenhsteve Posts: 78
    Thanks Mike:

    I gave up. My wife will have to take it to the shop. IMO, it is a poor design that would require a trip to the dealer to replace a bulb. Shame on Subaru..
