Freelander 1 Locking beep

ixan79 · Jun 7, 2019

Morning all, millions of threads about tailgate window problem, tried re-calibration but motor only ups the window 1 time in 100. I got it to the slightly down position and removed the fuse- perfect. But now it beeps the horn when I lock it. Can this be disabled?

Will probably not sound the horn if you lock it with the key as it doesn't activate the full monty security systems when locking on the key.

Can't help on the tailgate window closure issue. Mine is fine.

I can run you through the sequence I use to get it closed after the battery is disconnected (negative terminal off then back on again).

Does it beep every time? Mine beeps once in a while when locking only.

As an aside, isn't the horn beeping and lights flashing something to do with the 'self test mode'? Check out @Hippo's STM thread.
As I understand it, the output testing mode (inc. rear window) is connected to the internal central locking switch. Could be a something funky going on with ECU/CCU.

A quick blast of the horn when locking, means the CCU has detected a door or rear window open. It's warning you that only perimeter detection is active, and not the interior movement detection. There's no way to disable it, except for repairing the window correctly.

Thanks mate, but it does still beep (short horn blast) when locking with the key

Lucky you!

Maybe the calibration instructions i was following arn't right for my Landy, I disconnected the battery for more than 10secs, started engine, revved to 1500, pressed the window up button -nothing. (it said "press the window up button until it goes fully up and hear a beep to know it is correctly calibrated)
I think since it never goes up with engine off, and sometimes goes up with engine on, then it is needing too much power to start the motor.. motor replacement? or ???

OK thanks Nodge, I suspected there wouldn't be a way.
It goes down after shutting the door (with engine running and without) sometimes when i press the rocker switch it goes up with the engine running, but sometimes it just refuses. I can hear the electric 'bump' inside the rear door everytime i press the switch so the wiring is fine, it works sometimes so the regulator and motor are fine... I can't identify the problem so I don't know what to replace!

Could still be a dodgy switch. Maybe it works for a split second then fails.
Certainly the easiest thing to try first.

How does it know the window is not fully closed? I must be able to trick the sensor../

Window motor has a position sensor fitted. This position is logged in the CCU when the window is calibrated. If the CCU doesn't see the window is up by referencing the sensor, it sounds the horn.

STM self test mode is totally different ter normal vehicle operation. It's a method of testing the car. It provides a feedback ter items it senses happen like opening the bonnet. The internal CDL switch is only used as a method ter allow the owner ter interface with the Freelander, ter step through the sequence of controls.

Thanks Hippo.
Apologies for my ignorance. No courtesy light in mine so not sure tests can be done. I'll check it out and add data to your thread if I have success.

so maybe if I disconnect the motor? or can I reprogram the CCU?

All you need to do is make the rear window work correctly, then it's sorted.
