Hello

Somebody try to install original kick tailgate opener?
I already arder original ecu with sensors




The wire Lin B27 connect to the keyless go ecu. I don't have keyless to my car.
Anybody knows about the Lin B27 wire. Is this signal, of just a voltage output?








Thanks

smart kick controller
This module is an extension of the KeylessG to request both Opening & Closing of the trunk.


networked proximity sensor
Think of this module as a keyless door-handle sensor but for your feet and contactless.

You're also gonna need to integrate the other two optional modules in the CAN network. Are you up for the challenge to figure this all out?

When it works seamlessly, it's a real kicker.


(ECU: Engine electronic Control Unit)

For sure i will make it works!
I am electronic engineering, technical for medical equipment ;-)
If this is signal and not voltage output i will connect keyless go ecu to the output, then i connect the can b to the car.
Hope this will works

Controller modules need to be coded to work together, they are NOT Plug'nPlay.

yiannossavva

yes for sure need coding
i have xentry and vediamo software
sd connect c4

If the output is voltage i can do it easily. Just connect it with one relay in boot door handle ;-)

CaliBenzDriver

That's great!
Where did you get all your software?

yiannossavva

I have monaco too :-)

There are two major forums out there where people post hacked versions and explain how to install them. Unfortunately they cannot be named here, but if you dig hard enough you'll find a huge community. I suspect one of our favorite sponsors gets all of his information and software there as well.

My question is; Can you add this to a car without Keyless Go? I would love that, but I'm pre-facelift.

Don't bother! !

Oh, and don't forget to STEP BACK once you have activated the "kick-to-open" feature. . . or else the tailgate will hit you in the chin on its way up.

That is why this option wasn't offered on SUV's and wagons, I think.

CaliBenzDriver

What make this work only for the owner and not for anyone else, is the keyfob located by the KeylessG many antennas.

Lately my car computers have been working with very little latency unlike ever before. For fun I decided to push my luck little... I tried the ninja-kick with my keyfob located in the trunk: it just won't close. I don't know how keyless locates the key but that works.great.

Trunk sensor works similarly to a handle sensor by leveraging KeylessGo handshake with the keyfob. Leave it to the German ingenuity to build new complex features with service in mind.

I emailed him and asked him about just that. He assured me his software was licensed. Don't know, don't care, because ridiculously high-priced software and licensing to fix my own car is a big ****ing scam and I'll steal whatever I have to to get around it.

I don't get answer for my question.....
anybody knows what is the output wire LIN B27?

Thanks

CaliBenzDriver

LIN is a single wire bi-directionsl serial bus interface... used for slow control signaling, it's essentially a poor brother of the twisted-pair CAN bus.

yiannossavva

Thanks for reply

Can ii convert this signal to voltage output?

CaliBenzDriver

Are you trying to create "Trunk Open/Close" comand to drive a 12V relay... then how about reading the matching PID's through OBD2 ?
Good chance what you need is available.

If you bypass the keyfob validation done through KeylessG, anyone that walks by will be able to open your trunk !!!

Just like the main ignition is not an unsecured ON/OFF switch, the trunk kick must be secured.

+++++ a kludge solution:

​​​​​​Enable the kick module output only when car is UNLOCKED (so kick is then secured!)

Kick output emulate the trunk release button with a relay. (kick opens the trunk but can not close it without trunk motor.

The trunk lid button is disabled when car is locked therefore kick actuating the trunk button is secured because it is gated.

yiannossavva

Exactly that, convert to 12 volts relay.
I have already install aftermarket keyless go, the car automatically unlock when i am in 2 meters for the car, when i leave the car, about 5 meters automatically lock.
so, no problem if i can convert it to relay output ;-)

yiannossavva

My car have open-close button, i can open and close automatically (station wagon) not only can open it

CaliBenzDriver

Great! So you're no stranger to splicing your MB harness to make things better. I'm like that also to some extent, lol


Cracking LIN bus...
your kick module status will have to be captured through the LIN bus.

You'll need to interface it and make it work without handshaking with its KeylessGo parent module.

I would start there to validate this can be done. Until you can read LIN there is no kick_status that can be acted upon with a relay logic.

Live and learn

I find a cheap keyless control unit, i think is better to buy one.
The LIN connect-to the keyless control unit, and then the keyless control unit (connect) to the car by CAN B.
I don’t know what programming i have to do, but i think in this way i have a chances :-)
what you think?

yiannossavva

other way is to open a kick ecu and try to find a voltage that is change when activated ;-)

CaliBenzDriver

that would be the easiest for sure!

Hopefully your tailgate won't go flying open when you drive over manhole covers down the street.

Since you already have a simplified but working keyless solution in place, I would not mess it up for a chance to interface with CAN instead of LIN...

Whatever is easiest not to add more complications: the "KISS" principle.

yiannossavva

No way to trigger when drive, because tailgate ecu read the speed from the car via can bus, or read that the car is in lock mode. If i can find a voltage change in the kick ucu, i will drive this voltage to the handle switch via relay. ;-)
