Ok I know you remember the 80's??!!! Some of you might not remember the 60's
my question is this in the 80's vehicles when you opened the door of you car it would chime and remind you that "your door is ajar" Remember????
Well I need someone to help me with how exactly that worked, was the chime hooked up to the radio? was there a special box and speaker? I am working on a project that may end up saving many lives!!!! I need your help!

If I remember correctly they were electrical modules that were connected to the ignition which "chimed" when the circuit was "not broken" because the key was left in the ignition. In other words the circuit was connected with the key in, and not when the key was out. Confused now? : The chime was under the dash and resembled a small radio speaker.

This brings back memories, I think the first car I had that did this was a '79 Trans Am (yellow w/bird, probably the best car I have ever owned)...anyway, I know the message did NOT come through the radio, probably a little speaker hidden away somewhere that was triggered by the door switch..."your door is a jar" can't believe I still find that funny (I need a life!)
Good luck in your search to find the truth...what you have in mind will certainly be a great addition to auto safety...one child left in a car is one child too many.
The door ajar indicator system consists of the following components:
* The body control module (BCM)
* The instrument panel cluster (IPC)
* The driver information center (DIC)
* The driver door ajar switch
* The passenger door ajar switch
Driver Door Ajar And Passenger Door Ajar
The BCM receives a discrete input from the respective door ajar switch to indicate the status of the door. The BCM then communicates this status to the IPC via class 2 message. The IPC, upon receipt of this class 2 message, will illuminate the appropriate door ajar message in the DIC and also send a class 2 message to the radio to activate the door ajar audible warning when the following conditions are met:
* The transmission is removed from PARK
* The vehicle speed is greater then 8.05 km/h (5 mph)
I need to know how it works!!! besides being wired to the door switch! Where can I find the info if no one knows? Maybe a junk yard?
You desire to add a verbal warning of some kind. Connected to the door switch.
The equivilant today would be to use one of many chips that are available. They can be programmed with a recorded message that is played back on command. Hallmark has some greeting cards with that feature. I'd bet one of the more enterprising car alarm guys could make it work. It would be less difficult than say, remotly operatiing the roof.
Edit: I didn't actually mean any one to try to connect a greeting card to their vehicle. It was just an example usage of the kind of chip that is available.
Wow, it's amazing what you can learn from this site! It REALLY came through the radio?
It's why changing out the stock head unit for an aftermarked radio is a problem. There are chime adaptors that replicate the function, for those that cannot stand the stock radios.
I think the way to make this work would be to set it up like an aftermarket car alarm: a wire for the door switches, power, ground, any sensors needed for function and a brain box with the 'voice' contained as a package.
great idea! good luck!
I will see you in Savannah. I have one of the old boxes you are talking about, I'll try to find it and bring it. It connected in the fuse panel to the interior lamp circuit if I remember correctly.
You guys are the best, thank you so much for all your help. I have the idea but not all the education on the componets.
I find it hard to believe you can forget your child and it surprises me constantly that someone with this knowledge hasn't come up with something by now. It makes me very sad everytime I hear about this on the news and breaks my heart for the families involved.
I have seen the hallmark cards with the voice modules inside. I know there is a way I just have to find it. Also it will be done in as many languages as needed. Another thought was it has to be as enexpensive as possible so that people will buy it and easy to install so people will be able to do it themselves or for a very low cost.
Some of you guys actually gave me some part of the idea by the lights you installed under your dash and they were hooked into the door switch!!! Thanks to a great group of people here!!!

The module plugged directly into the fuse panel which was located under the dash. The radio was not involved in anyway. At least the cars that I am familiar with from that era.
Rather than dealing with the problem of drivers speaking many languages, why not have the audible signal sound like a baby crying? You could take it a step further, and have the sound change to a baby screaming if whatever triggers the system is still happening and the vehicle gets locked. It would work best if the scream sound was routed through the kind of speaker that alarms use (easily heard outside the vehicle); that way, if the driver didn't respond, someone else might.

You have to remember also that any warning device is only as good as the person using it. It must be turned on to use. How many people override safety devices on equipment because its easier for them, or they don't like the bells, etc. Those that are likely to forget a child in the car are most likely the same ones that would forget to set the alarm.
Seems like what you are trying to do is something I refer to as "A device to protect stupid people from themselves" Think about how many of those devices are on the market today.

Glenn,
Changing the radio with an aftermarket unit is not a problem if you use a Metra GMOS-01 Adapter module available from Crutchfield ($99). This unit will allow you to retain the door chime/warnings and will keep the radio on until you open the door just like the factory unit.
Note. Crutchfield first sent me the GMOS-04 unit which is the wrong one, that's if you have On-Star, which doesn't apply to the SSR.
I highly recommend all SSR owners to replace the factory radio with an aftermarket unit, amp and new speakers.
My enjoyment of my SSR has gone up 100 fold since I replaced the radio with a new Kenwood flipscreen, Amp, sub, and component speaker system.
The factory sound is god-awful, with cheap equipment, and poor speaker placement.

Do you know if the dealership can still access the body control module with their tech 2 computer now that you have your new audio system installed?
I installed a Kenwood 7015 GPS system and the dealer states they can not access the body control module on my truck. I did not use the GMOS-01 unit.
The part you are referring to was called (in GM’s terminology) a tone generator which gave off a chime if a circuit was left on. The unit plugged into the fuse box usually mounted under the left side of the dash. Back then we unplugged them to get rid of the noise. Last car I remember them on was a 1972 Olds Cutlass.
