Greetings All,
After a year of ownership, I am FINALLY getting around to programming my homelink in my 2006 C4S.
I have programmed many other cars, and have programmed my other 3 Porsches but my 997 is giving me issues. I know the following steps are used to program the car, but when completing Step 1, I do NOT get an amber flashing amber light. In fact, I never get an amber light if I press either of the 3 buttons.
Any suggestions??

1) Press and hold buttons 1 & 3 (2 outside buttons).
2) Release when small amber light next to buttons flashes rapidly. NO FLASHING LIGHT
3) Press and release button you wish to program. Amber light should flash slowly, about once every second.
4) Take your remote to the front of the car, as described in the 911 owners' manual, and press and hold button until fog lights flash 3 times.
5) Go back inside car and verify that the amber light is neither flashing nor solid.
6) Press and release the "learn" or "smart" button on the garage door opener. Important - don't press and hold, just press and release. There should be a light just above and smart button and it should light up and stay lit solid.
7) Go back to the 911 and press and hold for about 3 seconds the button you're trying to program. You may need to do that about 2 or 3 times.

Any help will be greatly appreciated.

 

I can't speak specifically to the 997 because unfortunately my overhead buttons aren't lighting up at all... a problem for another day.

But I just recently programmed a 2020 BMW using instructions other than what's in the manual and it worked the first time vs the manual instructions that didn't work. The manual used the "point the working clicker at the mirror" type process... Instead, try pressing the learning button on the motor. Then get in the car (within about 20 seconds) and press the button you want to use, then press it again. If it works your garage door motor light will flash and you are done. Maybe try that.

 

It looks like you may not be getting to where this applies, but if your garage door opener is newer, you may need one of these, as I don't believe the Homelink on the 997.1's is Security 2.0 compatible:

 

Right. I programmed my wife's 2008 987 with no issues, but I don't even have the light flash if I press any of the three buttons.

 

If you don't get any amber light when pressing any of the buttons, there's no point in going any further. I had a similar situation with my 997.1 C4S Cab.

I checked fuses, wiggled wires, and would often push the button when approaching the driveway just to see if I'd get a light. One day I got the amber light. I immediately grabbed the remote, (I never even turned off the engine) and started through the programming steps. It worked.

Since then there have been a couple of times I don't get the light and the door doesn't open. But most of the time, 90% or so, it works for me. I have no idea why it works now and didn't for the first several weeks of ownership.

 

I feel like the lights not coming on at all has got to be a wiring issue or a bad module. If you have Durametric try checking codes and activations there maybe?

If I have time later I’ll check the wiring diagrams and see if I can come up with any other ideas.

 

It looks like the Homelink buttons just connect directly to the main system control unit. So maybe just pull the button module out and make sure it's plugged in properly?

 

I have read that the fuse associated with the Homelink is B6 > 7.5 A, I'll check that when I get home,

 

That’s a good place to start. Once you get it working you will need a box to bridge the system in your 06 997 w/ the modern garage door openers. I had to install one to get the older home link system to work with my garage door opener. No issues on modern cars (in my case 2015 and later Porsche/Audi/VWs).

good luck, hope the fuse is the issue.

 

Mine is an 2007 997.1 C4S Cab. It works fine with my two year old garage door opener. I didn't have to add any repeater box.

 

I believe the homelink systems in the 997s were updated at some point. I definitely needed the repeater hardware to make my 06 997 work w/ a modern garage door opener. I believe there is a way to tell by looking at how the buttons are labeled. That’s what my garage door guy asked me to look at to determine whether or not I needed the repeater. Again, this is required between older cars (which I believe includes the 06 997s) and newer garage door openers. If you have an older garage door opener, you may not need it. It just adds an extra step of having to train the garage door unit in addition to training the car.

once you get it working, you can follow the instructions in the manual, if it doesn’t work it’s likely because you need the extra repeater hardware.

 

Built new house in 2020. It has LiftMaster openers, which are kind of cool because you can hook them up with a cell phone app allowing you to open and close (or check) your garage doors from anywhere in the world. You can also share it with trusted guests so they can also open your garage doors at their leisure. Incidentally, LiftMaster is another brand from the Chamberlain Group, which makes other brands of openers as well. I could not get my 2008 C2S can to link with HomeLink on my opener for love nor money! (Full disclosure, I actually did not try money).

Yet my car's HomeLink worked fine with my old house's (now defunct) Wayne Dalton opener, so I knew it wasn't the car.

All the comments above about not linking with newer openers are correct. I ended up getting a repeater based on previous Rennlist discussions, and it does work. It does not work spectacularly well in my case because I often have to just about have the bumper touching the garage door to be close enough, but every now and then it will open from out on the street. Be advised it can be a little fickle depending on your home's exact physical circumstances.

And if all fails, I can still pull out my cell phone and use the opener app.

Good luck!

P.S., Our new 2022 Macan hooked up to the garage door openers right away.

 

4 years in my 997. At some point I'll get around to programming the HomeLink. ;-)

 

Worth a shot, looks like that fuse controls a few other things too like the self-dimming rear mirror. Do you have that, and is it working?

I don't have a 997.1 manual, and the 987.1 manual doesn't have any decent details on the Homelink wiring. Assuming it's similar to the 987.2 (maybe?) the keypad basically connects directly to the "vehicle electrical system control unit", and that controls a whole bunch of stuff. It's unlikely that's bad, so I'd just pop out the keypad and check the connector, verify everything is good.

The Homelink transmitter is in the front right of the frunk, unclear if it's accessible from the interior or you need to remove the bumper. On the 987.2 it pulls power from fuse C6 (15A) via a black wire, but again 997.1 may be different. Data line is orange/black from the electrical system control unit above, and then there's a ground line (brown) as well.

It's not very well documented and spread across a few wiring diagrams so it's not incredibly clear, but that's what I've been able to figure out. I guess I'd check the fuse, check the connectors, and if it's easy to access the transmitter check for power and ground there. If that's all good it might just be a bad transmitter module I guess...not sure how you'd test for that without swapping in known good.

 

The Homelink transmitter looks like 99761822703, $1200 new, lol. So hopefully it's not that!

Some cheap ones on eBay but they might need coding, I dunno.
