    Hi everyone

    I have this thing under the hab seat which sometimes makes a high pitch tone when we are driving. The only way to stop it is to unplug it or switch off the engine. I have no idea what its purpose is. I assume it is an alarm of some description but I don't know what it is warning me about. I have attached a couple of pics to see if anyone might have some idea's...thanks...Steve

    They disappear off into some conduit with various other wires, the water pump is cited close but I don't think its anything related to that.

    so is the device a sounder or a sensor?

    you really need to track it to the other end.

    i'm one of these that would have to take the van to bits to find out what it is :Doh:

    Do you have an electric step and does it have a buzzer? Or is this it?

    No electric step, it makes a high pitch continuous tone, not always but sometimes, and when it does the only way to stop it is to unplug it or switch off the engine.

    I have no idea what its connected to and can't track the wires back without taking the van apart.

    I think it is a 'step out' alarm.. had similar on my Karmann

    have a look under the van beside the step and see if there is a switch that operates when you pull the step out.

    I have a manual step with alarm fitted so it doesn't need to be an electric step.

    I don't have an inverter. the step is built in as part of the van. I did once think it was an alarm to tell me a door wasn't shut correctly but have since ruled this out.

    i see you have a ci matiz and as you say there is no step as it is built into the floor of the van.

    have you ruled out a call / letter to the previous owner?

    I have one of these, connected to a low water indicator in the main tank. Just say you had water in there, but that it was slopping about whilst moving, exposing the sensor to the air, (no water covering it). Mine has a light and a buzzer though. Just an idea......

    I had a similar problem with this van & it took a while to find the source

    Found this underneath the rear end in a plastic box that wasn't sealed properly, a new one fixed the problem.
    Can you tell what it is yet?

    now that could be a possibility.

    Trailer wiring must, by law, have a telltale light or buzzer for the trailer indicators.

    If the 7 WAY CANBUS BYPASS RELAY (notice how i slipped that in :RollEyes:) has developed an intermittant fault (moisture ingress etc) that could be the reason for the buzzer activating.

    I had the same problem. Buzzer sounding intermittently even when parked. The canbus box for the trailer plug was basically in a tupperware box fixed under the van and the lid had come off allowing water in.

    Thanks for all the replies. I had a look yesterday thinking it may be something related to the water tank. Then I noticed this switch dangling which didn't seem right. Turns out that the external locker (which slides out) has this switch which is the alarm to tell me if I drive with it open. Somehow its become detached. So mystery solved. I just need to find out where it fits and secure it back in place...

    Cheers Steve
