I've searched for information regarding wiring a Limited garage door opener in a Base model, but came up empty.
Has anyone done this?
Also, I have a set of SRT wheels with factory tires (taken off when new). What would need to be done to wire the tire pressure sensors? I'm assuming the SRT wheels have sensors. Would I be assuming too much?

 

The garage door opener is also the transceiver for the TPMS.
I'm not sure if the wiring is present in the base. You can pull out the dome light and see if there is a 6 pin connector (with 5 wires) there for the garage door opener.
The TPMS sensors serial numbers have to be learned by the transceiver. I think you need a dealer setup to do that.

By the way, I just disconnected mine since the batteries have died in my 2004 sensors.

 

Thanks. I'm more interested in having the garage door opener working than the tire pressure sensor, so it may come down to just hooking up power to the correct wire and leaving the TPMS wires alone. I could tap into power for the dome light if there isn't an empty pig tail up there.

 

When I put an auto-dimming mirror into my '05, I researched the wiriing for the mirror and the garage door opener - you can find a diagram in this thread:

The diagram shows the appropriate pages of the service manual.

 

Nice. Thank you.

 

Disconnected what exactly? Is there an easy way to make the TPMS light disappear? Thanks!

 

Pin 2 in the connector to the garage door open turns on the light. Pin 6 is empty. I pulled out pin 2 (not easy) and pushed it into the empty slot 6, just in case I want to fix it one day. You can just cut wire 2 and tape off, easy.

Page 8W - 80 - 66 (pdf page 1539) in the service manual.

 

Thank you!

Any tips on pulling pin 2? Any heat recommended or just grab on tight and pull?

 

Saw-wheat! Another idiot light bites the dust this summer! I take it the manual shows all this too?

 

There is a very tiny plastic tab that catches a barb on the pin. If you can get something under the tab and lift slightly, the pin will pull out.

 

I just read a "how to" article on replacing the batteries in the valve stem sensors. Looks to be more trouble and expense than it's worth, unless you can get your tires demounted and mounted for free. If, however, you're getting ready to replace tires, it might be worth it. The cost to replace the batteries is roughly $5 each.

 

Link?

I'm looking at a new set of tires this summer and will pull the TPMS sensors. If I could replace the batteries, I could put them back in for the next set of tires.

Doesn't look easy, sealed unit that will need to be cut apart and resealed, but I'm always up for a challenge.

 

The only ones that I have seen that have had a new battery installed in them come from late 90's 'vettes.
I have searched and not found any more info on the repair. The new batteries are the lithium type 3.6v I think and cost around $5 each.
How hard can it be?

 

The article I saw was also on Corvette sensors. They are sealed, but the seal is easily removable, then you just reseal them. I don't know how different the Mercedes sensors are, so I was hoping that someone could add some info. Here's a link: the article starts on page 58 of the current issue (blue Camaro on cover).

I plan on doing mine this summer as well. My mechanic's real job is, managing a Goodyear store. So tires aren't a problem either. I will see what he knows about them and post my findings. He nor I think much about them, but when traveling, I could see how they could save you.+

 

I agree. I will be using my car strictly for traveling long distances during weekends in the summer, 1,000-1,500 miles at a crack. If I can get them working fairly easily, I'll do it.

 

Per the Crossfire Student Reference Book, page 82, the TPMS battery has a life expectancy of 10 years. A low battery function code from the sensor indicates the lithium battery is nearing it's minimum voltage.

 

As for the garage door opener I went to the homelink website and they had tons of vehicle specific info on how to set up. Mine was easy, press button on back of opener, light stays red for 30 seconds or so, during that time you press and hold one of the buttons inside car on the homelink button pad. Done

 

Canadian units are a bit different and there are special instructions for them.
