Bears happen. Here in Montana black bears do wander into our town (well, small city) and cause a lot of problems in orchards and dumpsters. Fish and Game or Wildlife and Parks will humanely deal with them pretty quickly. Usually they dart them and relocate them, sometimes trap. They almost never find it necessary to kill them. I've taken to carrying pepper spray when I'm in the mountains now (as much for wolves and cougar as for bear) and you might consider it. This is a pint aerosol that goes off with a very loud bang and sends a cloud of capsaicin. It has been known to turn charging grizzlies, which is a good trick. One experience with it will convince Black Bear to seek friendlier neighborhoods. Expect to pay forty or fifty bucks for a can. Local bear expert Jamie Jonkel says it will, in fact, deter 9 of 10 grizzlies .... There's no warranty for the tenth bear. You'd have to lay in wait for your bruin, so it may not be practical. I can imagine trying to convince my wife that I needed to sit up and stare at my trees until daybreak! Good luck. We all sympathise. :-)M

It is an ABS sensor issue when you are getting unintended ABS activation. With a good scan tool you can monitor ABS wheel speed sensor data and normally see which sensor the computer "thinks" is dropping out. It gets a bit more complicated than that, but for the "short story" you get the idea.

FWIW, I avoid aftermarket O2 sensors as much as possible. There is a clear difference in the O.E. part when it comes to accuracy and long term performance. That being said, when I see a part replaced and a code reset, my routine is to test the vehicle again from the beginning as if it has never been serviced the first time. This allows me to not assume that the part is either OK, nor defective. In otherwords, I test as if it's a completely different vehicle, and that routine allows me to solve problems that other techs/shops get stuck on. Cowboy is correct that even a lot of techs get stuck in the pull a code, change a part trap. The funny thing is, they get that way because it's what the public wants. While I have a diagnostic fee to just get started, they may attempt to give into public price pressure and try and do the diagnostics for a vary small fee, or even FREE. Well this is just like anything else, you get what you pay for, sometimes even less. Overall the worst thing that happens is after the owner spends a ton of money whether by their own hand, or with someone elses help and they have been unsuccessful with a repair, then they show up at a shop like mine crying how they already spent all that money and the car is still broke, almost as if it's my fault and now I'm supposed to make it right without earning a living doing so. Quite frankly when it happens too many times I am not afraid to send the customer permanently out the door. The most recent was a person that owns an Infinity Q45. They fooled around several times over the last few years, and each time I bailed them out. This last time they came to me first, I did the diagnostics only to see them take the repair to another shop for $5.00 less than I was going to charge! Heck they spent that $5.00 in gas just getting to that other shop and back home. Well they are free to make that choice, and now they can live with it, because between me, and the dealer, no-one else has full software support for their car, and it will never come back in here. My Choice......

Wow, those are beautiful! I was hoping to get a tree and donate it to Prairie Urban Farm since I don't have room in my backyard...
