Post # 10 and you are correcting folks? On spelling/usage?

Welcome to the forum.

Thanks for the schematics, Al! You are right on!

The schematics show what really happened. The left and right "stop/turn lamp supply voltage" signals come from the BCM and are shown as 'logic' which imply either a field effect or bipolar transistor as the switch... So, applying 12V to the intended output can backfeed through the transistor and provide current to charge the battery and / or drive the remote security circuitry - VOILA, the trunk now opens.

BUT - this is VERY dangerous to your electronics! Any time voltage is applied to the wrong side of a transistor, one runs a serious chance of blowing that transisitor (it is a very common ocurrence in motorcycle/quad ECM's).

Consider yourself lucky that you didn't damage the BCM -No offense and I'm glad you resolved your problem... but I would never suggest this because eventually someone WILL blow their BCM in the process.

You should capitalize that f in French.

Would you care to share that post? I've done an extensive search and I have found a few people who claim that will work but, when pressed, said they had not actually tried it. You are the first who said it would actually work even though the schematics show that it won't and will. at best. only force voltage back into the BCM computer through an output pin that show no internal connections. Are you sure you aren't confusing the oft posted recommendation to remove the tail light to pull the hatch cable?

Your tail lights came on because you put power to the stop light output contact wiring that goes to lights on both sides. You say the mirror lights came on. If that is true then that would indicate that the BCM was feeding power in directions it shouldn't have been since the mirror lights are not powered off the battery. They are powered by an A/C (square wave) voltage source inside the BCM. They also are not supposed to come on if you just open the hatch. This would indicate the BCM computer was either having software issues or power was going places it shouldn't have been.

But when you say the tail lights flashed twice (not three times) when the hatch popped, that takes a lot more power than just pulling the solenoid so that would indicate you were actually sending significant power into the BCM. Again, you were VERY lucky and I hope you do not see new issues arising in the future due to a weakened BCM computer.

Meant as humor. Many were criticizing the original post on it technical merits, this was my contribution. It's a joke son. I hope the original poster took it as such.

owc6

That's a first . No one has ever called me son, before.

cclive

Not even your Dad.....?

cclive

Actually 'voila' means 'there is' and 'voici' means 'here is'. Not to put too fine a point on it...LOL

owc6

Nope.

EVRose

Some people just dont get it do they?

owc6

Nope.

owc6

It never gets old, but I'd have thought better of cclive, by now.

;P

It was mid season 07 . The early 07s still had them seperate

Just for the record it was 2008. I have a very late 2007 with separate keys. The manual showed the integral key for all 2007s but there was a problem with production and they didn't change the lock design until the next year.

cclive

Me too...mine was made in the last 2 weeks of '07 production...thankfully I have the older fob design.

All i can say is THANKS FOR THE INFO, IT WORKS......
I was in the same boat, battery dead key in the car, took taillight out Hooked up jump box with some wire hit the remote pop goes the trunk took all of 5 mins
positive to the yellow and ground to the outside black wire...

What happens with a convertible, if there's no power to lower the window slightly to pass the top?

cclive

It's not a problem, the door can still be opened even with the window all the way up. But it is so much easier to just have a spare metal key, test it once in a while, and open the car that way.

LMB-Z

WOW!!! To the OP, glad you got it figured out...sorry about all your trouble. I did the same thing in my 06 Z. Took me 2 days to get back into the car. I did mine a little different. Lesson learned. Hope everything still works as it should.

nice post
the button on my fob is gone so i cant remove my key and i only got one set when i bought it. one day this will come back to bite me..........
