Default Radio and anti tow module

2005 coupe-two issues, not related.
1) the radio will not turn off after shutting the cat off and exiting.
2) the anti tow alarm goes off everytime you open the door-alarm and light blinking. It also retriggers its self while driving. I suspect and bad anti tow module-i thought it was supposed to be behind the right side truck liner-nope not there. Any idea where this module is located?

Thanks

Brian

Radio issue is common, I think it was just turn it off when the car is off and it will function normal after that. I remember there being a quirk with the stock radio being able to be turned on when the car is off.

The alarm issue is most likely the alarm siren in the wiper cowl.

Thanks, i found the siren under the cowl, what i was looking for is the module that trigger it. As for the radio, its seems turning it off manually keeps it off. I will live with that.

Thanks

If the radio is doing what you describe, I'd think the switched A+ fuse for hte radio is blown, but the battery fuse for the radio is NOT blown. That is, it has lost it's ignition sense.
Check the box under the hood, driver's side. THere are TWO fuses for the radio: 1 is battery feed, 1 is accessory feed.

If you are trying to troubleshoot something like this without the service manual, you are wasting your time.
The siren interface is easy, it is one wire:

It would be helpful if you told us when this happened, did it just come out of the blue or did you do something.

I have never heard of this issue on the Crossfire. If the radio had been changed or messed with in some manner the constant on power may have been switched in place of the switched power.
The OEM radio can be turned ON with the ignition OFF. It will switch OFF after a set time or when it senses the battery is getting too weak.

The two issues occurred had different times-the radio has been a while doing this. The the anti tow alarm started acting up.

Thanks for the schematic-but i still need to know where the module is located. The service manual (p372) said right side trunk-its not there.

I am going to check the fuses for the radio as suggested earlier. Hopefully that cures the radio issue.

Thanks again.

The anti tow module is in this photo, it is at the top right corner of the foam block and the bracket that holds it has a red paint slash on it.
What do you mean the anti-tow alarm started to act up?

Thanks for the picture...I will take a look.

I checked the radio fuses-all are good. I guess i can live with shutting the radio off manually before shutting the car off. This seems to keep it off.

Back to the anti tow alarm. I pulled fuse 9 which stopped the parking light from flashing(Alarm activated)-it also stopped the remote from opening the door locks. reinstalling the fuse, the lights no longer flash, but the door locks still do not work.

Pressing the remote light flash but the doors do not unlock.

Thanks again for all the suggestions.

You still have not explained what you call the anti tow alarm. There is no specific alarm for that as it uses the siren under the vowel in front of the windshield. This siren can be triggered to go scream for many causes.
Why do you say tow alarm? This expression causes confusion as in Ll my years here I cannot remember asingle problem with that sensoepr.

I couldn't deactivate it using the switch on the dash-so my thinking was that maybe the module has failed and is staying tripped. Fuse 9 stopped the alarm, which is the fuse for the anti tow sensor.

Maybe i am chasing down the wrong issue, but issues seemed to point to this anti tow sensor. It would also reactivate while driving, so my thought was the motion of the car was tripping the module.

At this point, if i disconnect the module and get my door locks working again i would be good!

Thanks

Pressing the anti hoist button will not stop the siren if the siren is being triggered by something else.
The siren can start if the circuit inside it is damaged by leaking batteries.
I would suggest that you access the siren under the cowl and disconnect it and start from there.
Quit the fixation on the anti hoist sensor as it is clouding your thinking.
The sensor in the trunk senses the rear of the car being lifted. You have to switch it off if your car is towed which is a no no or put on a flat bed tow truck.

Can you hear the pump in the trunk make a sound when the lights flash?

I have removed the siren. holding the tow which(with no alarm sounding) would not disable the tow alarm. Can't say i have heard a pump in the trunk? Pump for what?

I have to know what you call the tow alarm before I go any farther.

That would be the alarm that would go off if the back of the car is raised for towing. I assume the module in the rear of the car, trips the siren under the front cowl and flashed the 4 way lights for about 30 seconds.

There is a switch on the dash, that would disable this alarm for when you do want to tow the car. Pressing and holding it was suppose to disable the alarm for towing. The blinking light in the switch did not stop blinking after depressing the switch to disable it.

I guess my biggest problem now is getting the key fob to open the door locks...

I was not going to tell you what I thought you meant, you had to tell me.
That light in the switch should only blink when the car is locked.
I think your problem is the pump in the trunk which is under the foam in the photo I posted.
You should hear a sound when the buttons are pressed to lock or unlock the car, it also operates the lights to flash when the buttons are pressed.

You don't have a problem with the "anti tow" module - you have a security system problem that appears no different from the common ones we see, which are caused by:

1) Bad siren modules
2) Water damaged SSM/CLP pumps
3) Misc other electrical faults

Dave is right, you have GOT to get this "anti-two" thing out of your head.

The light on the switch blinks all the time.

Using the key fob the lights flash(so the pump is good?) but the doors do not unlock. This leads to another problem of opening the rear hatch!!

You keep making assumptions, the pump may be partly OK, normally the switch light flashes when every thing is locked securely with no faults but in your case as the doors are not locked when it flashes you have a problem.
Just because the lights flash does not mean the pump is OK, the pump gets damaged when water leaks into the well in the trunk and water accumulates.
Remove the trunk carpet and see if water is in the well under which the pump sits, this is the passenger side well. Slide a paper spill down the crack beside the foam blocks in which the pumps sits.
These wells are aptly named as they often have water in them when pump problems arise. Operate the fob with the carpet out and listen.

OK, no noise from the pump. but its dry-no water.

Everything worked(door locks) before a started pulling and checking fuses to narrow down a possible battery drain. I have a click in the relay right behind the fuse box when operating the key fob. Lights still flas but no door locks.
