Chrysler Repair: Alarm system still not disarming :what to do next?, straight pins, dash light


Question
Roland, what happens if that module has already been unplugged and plugged back in?  The service guy had it unplugged yesterday when I got there. He put it all back together today. I left the car with one battery terminal unplugged so the flashing lights and dash light alarm set did not drain the battery.  Will that offset and reset the fact that the module was unplugged already with the car dead?
Thanks
Gail
ps, I will try your new help if you think it won't matter that the module was unplugged.
I have the car locked and don't have the service station doing anything else.  I was upset that they disconnected that module without my permission since they don't seem to know what they are looking for anyway.

Hi Gail,
I believe that the only way to disarm the alarm without going inside the doors and repairing the broken lock wire switches is to go to the module for the system and fake it out into believing that it has gotten the signal from one of the door switches to disarm. Then after you get the car started and while the engine is running I would unplug the system and be done with it.
Here is what you need. Some basic tools (screwdrivers of both types of tips, some straight pins, a piece of electrical wire about 6" long, a flashlight and maybe an adjustable wrench).
First you have to get to the theft module which is above the glove box, in the dash. Begin by removing the underdash silencer pad on the lower edge of the dash so as to give you room to subsequently remove the glove box. Then notice around the glove box door opening that there are many screws that if you will remove them will allow the door box to drop down behind the dash. If the wire for the internal light bulb prevents the box from dropping down remove the bulb fixture and disconnect the wire.
Then look above the opening for the now-removed glove box and you will see a crosswise bracket upon which is mounted one or more electrical modules with a plug for each. To get at the theft module you need to remove the screws on either end of the bracket so that it drops down so you can get to the plug. The theft module has a 21-pin natural color connector. Once you locate that, do not disconnect the plug! Instead look for either a light green/orange or dark green/orange wire. Put a straight pin through the insulation of the wire so the tip of the pin touches the internal conductive wire. The find one of two wires that are colored black/light green and stick a pin thru its insulation. Now you connect those two pins together with the length of wire and then disconnect the wire. Watch for the alarm light to go off. If it doesn't, try again and then if it still doesn't go off try to reposition the pins sticking thru the insulation. Once you get the light to go off you can start the engine. Then while the engine is running pull the natural color plug out of the socket on the module. That will end you problem. Then reassemble the parts in reverse order.
That is the best bet I can give you.

Hi Gail,
Whether disconnecting the module put the system into a deeper shutdown state than it already is in is something I am not certain about. I would say that there is no harm in trying the work-around that I wrote to you about.
It may be that the only way to disarm the system is to communicate with it via a Chrysler Diagnostic Readout Box (DRB II) which a dealership will have, but that means towing the car there. So why not try the work-around? If it doesn't work then maybe the shop that disconnected the plug would be willing to tow the car to a Chrsler dealer at no cost to you. Let me know what happens.
