2009 DTS Issues

[River_Rat]

I apoligize if these two items have been covered previously. Just purchased a pre-owned 2009 DTS and am waiting on the owners manual but have two issues if someone can help. 1st is, that when the radio is on and I shut off the car, remove the key and open the door it continues to play. On my previous 2003 DeVille it would stay on for 10 minutes or shut off when the door was opened. 2nd is, that I can't seem to program the Homelink. I reset by holding both outer buttons until the lights flashed but can't seem to get the unit to accept the code from my handheld unit. Have never had trouble before with any vehicle including the 2003 DeVille. Where is the best spot to place the handheld unit when trying to get the Homelink to read the code? Thanks for the help.

Can't help you with the Homelink, but it sounds like there is definitely a problem with the radio.

if you have removed the key, it should turn off when you open the drivers door.

Thanks for the reply. Now that I think about it, the time (digital clock) stays on also and I haven't really checked to see how long, but I'd bet it's probably 10 minutes. This leads me to believe that the auto-shutoff is working but not shutting off when the key is removed. It still has plenty of factory warranty left so I guess I'll let the dealer figure out what's wrong.

OK try this.
If you cannot frind the book for the Garage door opener (GDO)(most of us can't..................) Get a ladder and see if there is a small button visible on the GDO. If there is try this......


Push the left and right buttons on the homelink in the car until the homelink light flashes rapidly.
That clears any old codes that were in there from the previous owner.

Park the car in the garage or just outside the garage.
Go back up that ladder and push that little button on the GDO(If there is a GDO god, it will be labeled "Learn" or some such............) If the door moves...........wrong button.
You will have about 30 seconds to get down from the ladder, get in your car and depress the button in the car you want to use.
You need to hold that button until the homelink light flashes rapidly.
That can take 30 seconds or so.
When it flashes, quit pushing the button.
It is now programmed.
When you push the button now the door should move.
Note - this button may react slower than your old buttons on the 03. That's normal.

Southern,

Very good explanation of programming the GDO.
I knew better than to even TRY to answer the gentleman, because I could not remember all the steps.

Now that I read it...I remember having to do exactly that...get on the stepladder and push the button on the back of the GDO.

And...my Homelink button does have to be held down for a couple of seconds to activate the GDO.
The remote that came with the GDO...acts INSTANTLY.

Southern & SuperJim:
My bad for not being real clear on what the problem is. I'm familiar with the "learn" button on the GDO. The issue is that after I clear the codes in the vehicle (by pressing the two outside buttons until they flash) I can't get the Homelink in the car to learn the code. What I've always done in the past (after clearing old codes) is to press & hold the handheld remote button I want to program, holding it next to the Homelink overhead in the car and at the same time press & hold the Homelink button I want to associate until the Homelink flashes rapidly. At that time I can go through the "learn" procedure that Southern explained. I can't get the Homelink to learn. I've tried holding the handheld remote everywhere near the Homelink until my fingers ache.

Thanks,
Jim

Another instance of having an older garage unit that doesn't have rotating codes? Where you have to read the code inside the remote and then manually program the car? Never could understand why I had to do this with my 08DTS when my 05 300C would learn the code from the remote....

[Southern]

OK. Vic may have a point.
If you have an old GDO, you are in deep doo doo and I know I wouldn't attempt to walk you through........


But assuming the recvr does have a rolling code, I did something very radical!!!!
I RTFM.

page 2-53 on the 2008 DTS. (The instructions I gave you earlier is what I did on my 2008 CTS)
This is what I did on my DTS.
Looks like the two units are different..............the DTS does not even call it a Homelink............

1- Push the two outside buttons for 0ne to two seconds only. This does not remove old codes........it just puts the unit into
programming mode.
2- Find the button on the GDO. They say it is usually near the hanging wire antenna.....
Push that button!

NOTE: If there is NO BUTTON. VIC is right and you have an old non rolling code Recvr and this procedure cannot work.


3- Return to vehicle......you have 30 seconds..no need to fall in your haste......press and hold the button on the Universal Home remote that will be used to control the garage door. You may have to hold the button for up to 20 seconds. The light above the switch should slowly blink.
4- WHEN THE GARAGE DOOR Moves, IMMEDIATELY RELEASE the BUTTON!!!!! The indicator light should now blink rapidly
until the programming is complete.

5- press the button again . The Garage door should move now, confirming that it is programmed.


BOL!

Cudos to Southern Jim.....I followed your instructions and it worked perfectly on both garage doors (I do have the rolling codes). What's interesting though is that any vehicle I have had (Park Aves, 2003 DeVille, Toyota Sienna, and a Durango) I've always had to hold the remote garage door unit next to the Homelink and let it mimic the code then use the "learn" button on the GDO. Of well you "learn" something new every day. Now if you could just help me figure out why the radio and digital clock stay on for 10 minutes after the key is removed and the driver's door is opened I'd be golden.

Thanks for all the help from everyone.

In my case (2008 DTS with Homelink), the learning process would not work because the old garage door opener (GDO, I believe) not only didn't use rolling codes, it was on a different frequency that is no longer used for GDOs. Lear sent me a unit for free that connected to the same terminals as the indoor push buttons. After that everything worked fine (new car, old remotes, indoor push buttons, etc.). I might note that the three CTS-Vs I have had (2004, 2005, and 2009) all learned the code from the original remote opener. There was no indication that any of these cars use the Homelink system.

River Rat,
Regarding the question about the radio staying on when the driver's door is opened, I would say that the system doen't know that the driver's door is open. The radio and a few other things remain powered by the RAP feature when the ignition switch is turned to the OFF position and the key is removed. This is normal. The RAP feature keeps battery power going to these things for about 10 minutes if none of the doors are opened. The fact that these things continue to be powered after the driver's door is opened indicates, that the system does not know the driver's door is open. A bad switch perhaps? You don't say what happens when doors other than the driver's door are opened.

[River_Rat]

Ted:
Good thought! I tried all 4 doors and the radio & digital clock still stay on. The door switches must be okay because the interior lights come on when any of the doors are opened. Guess I'll have to let the dealer figure this one out.

Thanks again,
Jim

Opening the drivers door "SHOULD" turn off the radio.
You are right...you will probably have to let the Dealer sort this one out.

On my 2006 DTS, "ONLY" the drivers door opening will turn off the radio.
Darling Wife can open her door, and it has no effect on the Radio.

ANY door opening turns off all other retained power, such as power windows etc...etc, but not the Radio.

Before the Radio was replaced for fading trim, "ANY" door opening, would turn off the Radio.
I have NO IDEA why this Radio is different from the original Radio.

I don't think the new radio is any different from the old radio. It is likely that the new radio gets its power from a different source due to the way it was installed. Why the installer would have a choice and why he would choose a different power source is a mystery. In all Cadillacs I have had recently (2004 CTS-V, 2004 DTS, 2005 CTS-V, 2008 DTS, and 2009 CTS-V), the radio is powered off when either the driver or the passenger front door is opened.

You are correct.
The NAV/Radio is exactly the same...as far as I can tell.
It is the "OPERATION" of the NAV/Radio when the front doors are opened that is different.

The original NAV/Radio would turn off when "EITHER" of the front doors were opened.
Now, it only turns off when the drivers door is opened.

It's no big deal...just different operation than the original one.
