Enabling Daytime Run Lights and Courtesy Headlamps

[twr7cx]

Has anyone had any success enabling Daytime Run Lights and/or Courtesy Headlamps using a Nanocom?

Following the instructions in http://web.nanocom.it/download/VALEO%20BCU%20_DISCO%20II.pdf :


Daytime run lights: Legislation in some markets requires that the headlamps illuminate
whilst the vehicle is moving, or the ignition is switched on. This function is referred to as
"daylight running lamps". Therefore, the BCU, which controls illumination of the
headlamps, must also be programmed to accommodate the legislative requirements of
individual markets, with regard to daylight running lamps. The options are:
× The vehicle does not require the daylight running lamp feature to operate in any
circumstance (NONE).
× The daylight running lamps will be on if the main beam head lamps are off (NO MAIN).
× The daylight running lamps will be on whenever the main or dipped beam head lamps
are switched ' off' and the gear selector lever is in any position other than ' park' (NO
HEADS).
· 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.

But after enabling and writing the settings to the BCU, neither seems to be functioning on my vehicle...

The vehicle is programmed to run on an Australian build vehicle.
In the Australian specs/ADR's this is not a feature & will not work no matter how many time you tell it too.

But

If you change the build to say Scandinavia, they will then work a you have turned them on.

I've done both. On a 99-02 you'll need a resistor that plugs in behind the left headlamp for the DRL to work correctly. Not quite sure about D2a. It just seemed to work for me. Also a couple of relays in the under dash fuse box. The courtesy lights were already enabled when I bought it. You just hold down the lock button on the remote and they'll come on with a timer.

Will anything else change or be effected if I change the build location?

It could want to drive on the wrong side of the road or chase reindeer!:Rolling:

PS: Mine has always had "Courtesy headlamps" enabled

[MarknDeb]

Yep i have set mine with the nanocom evo, when you set them and start the car they do not come on so i thought it didnt work but found out the secret, it is that they do not come on until you put the car into drive.

Is your vehicle still set to Australia build?

I have checked and mine aren't on in drive either.

Do you have the drl relays installed in the under dash fuse box?

[MarknDeb]

Yes mate mine is Australia build, the setting is "NO MAINS"

You need to have grey hair, wear a lawn bowls hat to enable the Volvo Mode on the lights

I just poked my head in under the dash and it looks like every fuse and relay fitting has something installed in it - the vehicle is an HSE so should have most of the bells and whistles.

However, the vehicle doesn't have the factory driving light setup - it never has, the driving light set up on it is an aftermarket install and I have used a factory driving light switch on the dash.

I thought fog lights/driving lights in the bumper were standard on HSE? Maybe some1 changed the lights?

Fog lights and driving lights are different. I have the standard fog lights in the front bumper. The driving lights were an optional accessory and fit above the bumper.

[schuy1]

Ok, They were what I was referring to and I think jafir may have been thinking of them too, which is why I asked. As the fog lights were standard there is a fair chance their relays are the 1s they used and not optionals maybe. would make the running lights enable a lot easier for a dealer perhaps. Anyway was just a thought.

Somewhere on the interweb is a detailed tute on modifying the wiring to get DRL without having to use the resistor.

I have the modification and I can deactivate/activate the DRL using Nanocom. IIRC you create a wiring link behind the fuse box in the passenger compartment. I also have an inline switch mounted in the left binnacle so I can choose to have DRL on or off. Very handy when things get a little hairy :eek:

For the life of me, I am unable to recall where the tute came from :confused:

Actually there are relays, in the under dash fuse box, that are just for DRL. Not for fogs or for driving lights. Here is link with photos: Daytime running lights (DRL) not working, relay? - DiscoWeb Message Boards (http://www.discoweb.org/forums/showthread.php't=82566)

The photos show a D2a style box, with a metal jumper in place of one of the relays. My 03 is setup that way. On my 1999, it had a relay in that spot. Also, the older vehicles had a resistor behind the left head light. If not installed, there should be a jumper there. Here is a TSB for North American Spec discos talking about the resistor, or lack thereof. http://www.landroverclubvi.com/uploads/2/3/9/8/2398536/resistor_installation_needed_for_8609nasf_1.pdf

Ahh, Thanks for that, the muddy waters are clearing . Mine is a late 02 model but to be honest I have not looked at it, only at the rave.

Is this link working for anyone? I am just getting:

Here is a picture of mine (2003 D2a):

As you can see there is a metal jumper in place there on the top left - I assume this is what you are referring to.

Yep. So it looks like they are all there. The jumper and the top black w/ green stripe relay are the DRL relays. Perhaps that relay is bad? My 03 didn't come with fog lights, so when I needed a relay to activate them after I installed them I borrowed the DRL relay, because I didn't need it. Perhaps a repair shop could have done the same thing at some point, borrow an unused relay to fix something for you, and they just put the bad relay back in that spot?

I'd try swapping it with something else like the air conditioning relay. Worth a try anyway.

I started playing with this again this evening.

I tested the relay, and no issues. Swapped it over with another one that I knew worked, and still no effect.

I then put the vehicle in drive (running) and held the relay on the pins, and I could hear the relay internally click! So the BCU is trying to activate the DRL (and the relay works)! It seems that somewhere after this relay the lighting power signal is getting lost...

[twr7cx]

Well, I've got no idea and have given up on these now.

The relay defiantly works, can feel it click.

Connected the Nanocom up and they work while the Nanocom is connected, disconnect it and don't work. Strange.

[MarknDeb]

HMMM now you own a landy so from the start you should have realized it a had a bloody good chance that it would have a problem, even tho it didn't work its not the cars fault it would be the human side that put her together at the start so don't blame her :p:angel:

[budgie]

I enabled daytime running lights (04 D2a) and found myself replacing the globes every 2 to 3 months, so I disabled it again ...

You're not changing the build country, you're changing the market it was sold in.

Who knows, you might enable the Scandi Flick....

Recently purchased the round ************ 130w lights with the plate (this is now flat by the way and does not require tabs and bending to fit - had held off putting them in due to my broken shoulder and having to bend them, opened the pack and found out I don't have to) and these have a DRL function. Was not concerned that they had the DRL as did not think it was available on the D2, then this thread pops up!

Have had the Philips Ultimum LED in the headlights but they did not seal well and the headlights are a little brown inside. These LED's were great by the way and gave a good spread of light, it was not enough for night times up in the High Country by themselves though, so was looking to put in a set of driving lights. Was told about these 130W lights by a mate who swears by them. So now thinking I may just install a light bar on the roof rack and keep the radiator clear.

The units themselves are genuinely surprisingly solid heavy units and guaranteed to be legal. May as well use the DRL function if it is so simple to do.

Yeaaaa, I don't recommend that.

I had to drive my TD5 manual a few days in the winter (with ~15cm fresh snow) with no front prop and the center diff locked. With studded proper winter tires ofcourse.

It'll drift and slide nicely, but on the rebound.. .all hell will get loose and You might just need a pair of clean undies [bighmmm]

I was driving mine like that a while back. Just Melbourne wet roads was enough for me.
