Hello friends,

I need your help.
After the alarm system was somehow deactivated last time when I locked and unlocked the car with the key in the door lock, I was actually quite happy and had no more problems until this week.

But now I had the car n the workshop and somehow they had drained the battery completely what activated the alarm system again. However, this time I can't get it deactivated anymore at all.

I think that it is not a factory installation because:
- a retrofit LED is installed in the dashboard and
- a cable with a button is dangling loosely behind the steering wheel cover.

But I can't find a controller.

The situation is as follows:

- The system activates automatically a few seconds after the vehicle is locked => the LED flashes 1x every 10-15 seconds.
- As soon as the car is unlocked and the door is opened, the system starts to honk.
- With the ignition on, the alarm is silenced by pressing the above mentioned button. Without ignition, only the LED stops flashing, but the horn continues.
- If the ignition is switched on by pressing the button while the system is armed, the horn sounds 4x briefly and the LED flashes quickly. Pressing the button again makes the horn sound 3x again and the LED is off. However, only until the next closing again.

If anyone has an idea based on the description or maybe knows what system is installed, where I can get instructions for it or who I could possibly ask about it, I would be super grateful for any hint. I can't expect my neighbors to have the alarm system go off every time I get in.

The wires that goto the LED and that cable has to lead back to the controller, you'll need to start disassembling the dash as you follow them to the module.

Thank you for the feedback.
Yes, I'm aware of this option. However, there are so many cables in that area that it's not possible to trace them without actually disassembling the dash. So, I was hoping someone knows the type or brand of the system by the reaction described and I could try to get a manual. If I disassemble the dash and find the system, I will take it out directly.

What you're describing is an aftermarket alarm system that should have it's own FOB.

Usually, with this type of alarm, you would not ever use the factory FOB to unlock, only the alarm system's FOB.

Without the specific FOB that is coded to the alarm controller, you can't do much other than finding the controller and disabling it.

Did you recently buy this truck?

The kick plate below the steering column only has 2 screws to remove and easily pops out, better exposing the wiring beneath the dash. This may assist you to trace wires from the push button you described, to locate the alarm controller.

Check YouTube to learn how to remove this panel, it's very easy.

When the alarm is triggered and the horn starts honking, do you hear any other loud beeps, chirps or siren noises that are obviously not coming from the factory horn?

Aftermarket alarm controllers are sometimes installed in the engine bay and have their own siren or buzzer of some type.

This buzzer or siren wiring might be easier to trace to the alarm controller module and allow you to locate/remove the power connection to the alarm.

Another place to look, is the positive battery terminal area. Often, amateur aftermarket alarm system installations are directly connected to the battery terminal. You might notice a crimp lug that is obviously not part of the OEM build.

This sounds like an amateur installation, you may be able to locate the alarm controller by just looking to find a box that is poorly mounted and obviously not part of the OEM build.

The alarm controller may be mounted under the dash or in the engine bay.

One way or another, you have to locate the controller and disable it.


And welcome to Ram Forum, Simon. :cool:

Without seeing the module there's no way of knowing what brand of alarm it is.
Try pushing the button while the vehicle is on, if the LED turns on and stays on that maybe valet mode.
Without knowing what alarm is in the truck, your best to get that alarm removed so it doesn't cause you problems down the road

And welcome to Ram Forum, Simon. :cool:
Thank you for the warm welcome. Feels really good to be here.
It's not that easy to find people with detailed knowledge about these trucks over here in Germany.

Did you recently buy this truck?
My son bought it beginning this year. First, there was no issue with the system. It worked like expected. Some occasional blinking LED that stopped as soon the car got opened. Once, as I played around with the key code to check for errors we had the first time an issue with this system, however managed to somehow deactivate it again. But everything we think we've done last time, doesn't work this time.

No, there's no other sound we can hear.

Yes, if there's no quick and dirty solution, we will definitely go for this.

I'll keep you updated...

Best Regards,
Simon

The only quick solution would be to contact the seller of the truck and hope they can provide the aftermarket alarm FOB.

The dirty solution is to start chasing wires, locate the alarm controller and disable it.

Removing the panel under the steering column only requires a few minutes and hopefully will expose the path for the pushbutton wires, leading you to the controller.

Leaving this device active will compromise the reliability and your enjoyment of the vehicle.
I'd bet your neighbours don't much appreciate the erratic horning sessions. :cool:

1) Turn the key to run.
2) HOLD the botton down while watching the LED light.
3) Once the LED is illuminated release the button and the LED should stay ON.
The system is now in VALET mode and will no longer autoset and be deactivated until you hold the button again or lose battery power.

Thanks for this additional tip. We will check this, too.

After today's investigation for the control unit without any success (neither behind the dash nor in the motor bay), I don't think it's a cheap aftermarket unit.
After some testing and playing around, I could find that this system is really deeply connected to the system (horn, lights, ignition switch, locking system). And I could get the system into a mode in which altough the LED flashes but no alarm sounds - I call it mode B.
Youtube video: mode B
Mode B and mode A can be toggled by turning key to ingition an back to off several times.
Youtube video: mode A
And then, there is some special mode, however I don't know how to get use of it
Youtube video: mode xx

So, at least I can get it to mode B where no alarm sounds, but I still haven't back the mode where nothing is flashing or sounding.
Some more testing will follow ...

I think that's the mode in which the system was before the power loss.
But I can't get into it anymore. I tried different variations to get into the state where the LED is permanently illuminated - without success.

So, we'll keep it in what we call mode 'B'.


Just one additional question: As I searched for any control unit, I thought the respondig cables were among a big bundle that goes into the remote start unit. However there's only the main plug used, the plug for remote start is free. Afaik the remote start also has access to horn, signal lights and motor controls. Is there any alarm system in the remote start unit included?
