problem, db chdl7p2, 2007 chrysler 300c

Vehicle: 2007 Chrysler 300c

Alarm System: Scytek_Astra 4000RS w/remote startTransponder: Omega_DB-CHDL7P2

Things that work

The car starts and runs properly using the factory keys.  The car starts and runs properly using the Remote starter remote.The transponder sends the car alarm a negative pulse when I open the doors….meaning the DB-CHDL7P2 is reading the car’s data line and telling the alarm the doors are open.

Here is the problem I am having.

The alarm remote do not lock unlock doors / open trunk /or deactivate the factory alarm.  Reason:  the transponder is not taking the signals from the car alarm and communicating it to the car’s data line.

Troubleshooting……

If I activate the lock or unlock buttons on the alarm remote I can see the negative pulse going to the transponder’s lock pins 2 or unlock pin 3. If I select the trunk open button on the remote I can see the negative pulse going to the transponder pin 8.

I also ran a ground wire for 1 second across each pins (2, 3, and 8) to see if the transponder would lock, unlock door or open trunk.  Nothing happened.

The transponder is connected up correctly because the remote starter works.  I used the MUX system provided by the transponder to apply the correct resistor values. Plus pin 4 of the transponder sends the car alarm a negative pulse when I open the doors.

I tried to reset the Doorlock Interface  by pressing the program buttons until I got Mode8 option2 “Complete reset of option and mode” .  Still same problem.

Have anyone seen this problem before.  What should I do next.

My wiring connections are below

All my connections are soldered.

Don't panic, it happened to me once in a 2004 caravan. I had to put two relays to strengthen the triggers. Try o ground the blue wire of the module and see if thst unlocks the doors. otherwise, call the tech support and talk to Fredi, he is the one who will help you out. Good luck.
