On the Disco 2, there is a feature on the headlights that when you press and hold the lock button on the key fob, the headlights are supposed to come on for 30 seconds or so. I'd really like this working as I live in the country and am often in areas with no light.

Mine ain't working. I've had a look with Nanocom and with Hawkeye (just for good measure) and both say that it's enabled. I've disabled it and re-enabled it just to make sure. Still not working.

Anyone able to shed light (no pun intended) on this?
 
Programming/courtesy lights/

Set to enable and then written. I know that the wright worked as The key left in warning was also enabled and that started working.

When it didn't work it was set to disable, written to, tested and then re-enabled
 
Nope, and everything else works just as it should. It's really puzzling me. I guess there has to be a reason, I just can't quite put my finger on what it might be.
 
Did anyone find a solution to this, my fathers discovery has the same problem and i have enabled it with hawkeye to no avail.
 
Im afraid that it seems to be one of those things !.

Mine is the same. No matter how I try, this feature cannot be enabled.

Good old LR.
 
According the the D2 owners handbook the on for 30 sec. is the default function and only removed if the owner requires it tobe.
But then D2 owners will know that.

Its always been disabled since he has owned it, when I went into the bcu programming with the Hawkeye it was set to disabled which I changed to enabled, would there be a relay as its timed for 30 seconds or does the bcu time it
 
Both, BCU to look after the timer function and I would think a relay to do the switching of the lights, but I can't find the relay listed in the D2 Electrical Library 1999-2003 which shows the relays in both fuse boxes.

Ok thanks was it rave that you looked on.
 
I found this on the Nanocom website.

Courtesy headlamps: The BCU can be programmed to turn on the vehicle headlamps
when the driver presses the remote transmitter. The BCU switches both headlamps on by
signaling to IDM to switch the headlamp relay ON.

Does anyone know what the IDM is.

Intelligent driver module - works like a 2nd BCU (apparently)
 
Here you go:
RAVE said:
The BCU also communicates with several other electronically controlled systems such as the EAT ECU and SLABS
ECU and also has a datalink between the Intelligent Driver Module (IDM) and the instrument pack. The datalink is a
low speed bus capable of transmitting and receiving messages at a data rate of 10,400 bits per second. Additional
inputs and outputs to peripheral devices are included which are necessary for determining vehicle status for particular
logical operations e.g. crank, ignition key inserted, fuel flap enable etc.
The BCU receives its power supply from the engine compartment fuse box, and is protected by a 10 A fuse.
The BCU communicates with the IDM to provide the control signals to perform power switching operations in
conjunction with dedicated relays.
IDM
The IDM is integrated into the passenger compartment fuse box, which is mounted behind the fascia below the
steering column. There are no harnesses between the fuse box and the IDM. The IDM performs the power switching
operations for several of the vehicle's electrical systems.
The IDM communicates with the BCU and the instrument pack via a serial interface. If the BCU or the IDM is replaced,
the communications link between the two units has to be re-established. This can be done either by switching on the
ignition and leaving it on for five minutes, or by using TestBook. The vehicle immobilisation will remain active until the
communications link between the BCU and IDM has been re-established.
