Installed home link. Cant get it to work.

[JayTee82]

Hey guys. New to the site.
I just installed a overhead console with complete wiring harness into my 14 tradesman.
I have the 7" EVIC installed too. I know I probably don't have the CV2 option turned on, which I probably my problem.
Wondering if anyone knows how to turn it on with the Alfa OBD tool?
Any help would be appreciated.

Thanks!

I don’t think you have to flash anything for home link. I had the overhead console without home link, swapped out panels and homelink worked as advertised. I did follow the the directions for clearing old codes and reprogramming to my garage doors.

Yea, but i didn't have a overhead console or anything. I think that my issue. i think i may need to turn on the CV2 or CUN codes in the BCM. I would think it should work as long as it had power ( and it does) but when i press the button it doesn't show anything on my EVIC. So i have no idea it its really working or not. I have the Alfa OBD tool, but i havn't found anything in there for Home Link or console that will get it working.

Did you have a wiring harness to plug it and power up the homelink?

Yea. I got the console with the complete harness out of a laramie. Has homelink, sunroof and rear slider switch.

There’s no actual sales code or setting for the homelink itself, but, the overhead console contains the compass, and that’s what gets enabled when you add the CV2 sales code. Those who already have the overhead console/compass without homelink only need to plug in the homelink module for it to work. Check these settings in alfa car configuration change:

VehConfig 3- display compass heading present- yes

LIN and misc- compass mounting orientation- upside down

Just checked. Both of those options are set correctly.
I not really sure what I'm missing here. My EVIC came out of a 14 BigHorn.
My overhead console setup is out of a 2016 Laramie.

id really like to see the connector end view for the HomeLink module.
Im thinking there might be a issue with the data link between the homelink and EVIC since i never get any message on the EVIC when i press the button. i know i have power because the homelink back lighting is on.

the lin bus wire must be used.

 

[JayTee82]

the lin bus wire must be used.

Any idea where pin 3 (Lin Bus) goes? Front connector at A-pillar or back C pillar. I can then check the other side of that connector and see if i have a pin there.

 

[JayTee82]

ok i found it. It goes into front a-pillar connector, cavitiy 2. I've got a wire on the other side too. So data line should be fine. I wonder if i have a bad HomeLink

Check this one also:
LIN and misc- EOM present- yes

 

[JayTee82]

Thanks. Ill check that when i get home tonight.
I also just noticed last night the small light in the console that lights up the cup holder area isn't on. It's just a simple two wire LED.
Wondering why it's not on? Any chance you know the schematics on that or how it's powered up? I would assume it's always on with ignition like our Cadillacs.

That should be it’s own separate 2 position connector. What do you have it hooked up to?

 

[JayTee82]

Hmmmm.... wondering if Im missing part of my harness in the roof.
I know i had two spare connectors i left up in the headliner. I know one went too the sunroof motor(which i don't have). Wasn't sure if the other one was maybe a over head DVD player.
Only two plugs i have plugged in from the headliner are the one at the L/F A-pillar and L/R C-pillar. Assumed most everything through those two. I never had anything run down the R/R or R/F pillars

Is that the green connector on the drivers side?

LIN and misc- EOM present- yes

That was it!!!! Works like a champ now and programed right up!! Thanks a lot man. I had a feeling it had too be data related.

Yes

Ok so i found the plug on the R/R c-pillar, and sure enough there is a connector there with a white/green wire in cavity 6. I bet that second plug was supposed to go down there. I'll have to find out how i can reroute that harness up there to come down now.

 

[magician]

Yes

And pin position 2 is the lin bus? For the Homelink at the green connector?

If so, I’ve been looking for this for three years....
