High beam, Low beam & park lights cutting out

High beam, Low beam & park lights cutting out

Postby Mitsu0069 on Wed May 25, 2016 9:22 pm

Hi,
I was driving to work this morning, and I had my headlights on with my led light bar going, and all my lights went out. My high/low beam, parks lights the whole deal went out, and tearing around a corner then all of a sudden she's all dark, I nearly had to turn around and get a new pair of undies :shock: . I flicked the light stalk like mad and turned off the led bar and the lights came back on but I drove in to work with my low beams. I checked the battery terminals and the earth body connection next to the battery, checked that the 2 relays are tight in the fuse box.
I just found a wiring diagram of the headlight system and it looks like the common thing to the relays is the power supply which comes through a fusable link, but im not sure if the park light system works of the same fusable link.
I have tested out the lights tonight and they worked ok, but im driving around thinking when is it going to happen again.
Has anyone experienced this problem or has any ideas of where to look.

The ETACS module is also a common part of that system. I would say that all your lights were told to turn off by the ECU.
I would be looking for a control problem, not power.

If you blow a fuse, or fusible link, then power will be lost until that fuse, or link, is replaced. Yes, it's possible for the fuse or link to overheat and not blow completely, but unusual.

So, that fact that your lights came back indicates a problem elsewhere, i.e. not in the power circuit, as ag9111 suggests. Where have you connected the light bar? Have you used any wires under the dash for power, or even switching power for a relay? I'm thinking overload in the ETACS circuit which may be protected by a circuit breaker of some kind that reset once the load was removed and circuit cooled down?

Garth, where did you get that circuit diagram? The one on the right in Headlamp1 is for a dual pocket light, something we've never seen here, in fact quite rare anywhere. Note also that it has levelling provision in a halogen light, also something we haven't seen here.

From one of the Russian forums so its a universal cct diagram. It has lots of option items like that.
I think I got the link from Dave.
I'm at work, I will see if I can find the link or source document tonight

Yes probably euro. I have the part numbers for those lights but the plastic skirt underneath is a different shape to ours. :cry:

There are euro tritons with it. L200s I should say.

Thank you guys for your input. All my lights operated correctly this morning :)
I have connected my light bar through a relay to be switched by my high beams, I have some switches in my dash that are illuminated by the cigarette lighter light when the park lights are switched on. Everything has worked well with no problems for the past 3 years. I will pull the dash apart and check the wiring to the switches to see if nothing has rubbed through, hopefully I will find something.

Looking at the wiring diagrams, I'd be looking at the connectors related to the column ecu, door switch input and ignition switch input.

Actually your ignition switch input may be a starting point - I've had a couple of dicky ones in past vehicles.

Strange as it sounds I found led park bulbs played havoc with lights and dash lights

I would start with the light switch (stalk) not uncommon to fail causing this issue.

It seems I'm not the only person to have this problem, got the recall notice today in the mail. Definitely is the problem, if I turn the lights on and wiggle the stalk they all cut out sometimes. I will talk to Mitsi and get it sorted before I'm In the dark again :o

Yep I received a recall notice from Mits yesterday 17 Aug ,the letter mentions dust getting in the connections and causing the headlight /dimmer /indicator switch to fail.

We got for both the NT pajey and my MN. Also know two fellow triton owners similar vintage to mine with the airbag recall

Thought I'd just jump on the back end of this thread as opposed to starting a new one.

Having a weird occurence with one headlight on my MN. Drivers side low beam and parker have not turned on for a week or more now, high beam is fine. I have cleaned earth points, cleaned plug with contact cleaner, checked fuses, swapped globes but same issue.

I can always get the lights to work but I have to wriggle and tap on the back of the globe plug, some times tapping the main globe gets the parker to turn on some times the other way. Some times its one tap some times I have to pull the plugs off and get more aggressive but they will come on, and stay on until I turn them off again no flickering or funny business once working. But if I turn them off they will need a tapping to come back on.

I like to think I can work through most things 12v but this one has got me scratching my head in a big way. Any ideas what to "tap" next to try and figure this one out?

Sounds like the globe contact in the plug have been pushed in and are not contacting correctly?

Yes I agree, but I pulled the back off the plug yesterday and checked that out all is fine. So unfortunately I don't think that's the issue. If it's a loose plug I'd expect it to cut out at times as well. I drove 2.5 hours the other night and once it was on stated on the whole way, switching between low and high doesn't impact it either.

Was playing around again last night and if I turn lights off and back on within about 10 seconds then the light stays functioning. If I leave them off for longer than 10 seconds some tapping or wriggling is needed.

If we look at the wiring diagrams we can see that, other than at the ETACS-ECU, there is no common wiring between the headlight and the parkers on the positive side. However, they do share a common earth ("6" on the configuration diagram). This, or the wires leading to it are where I'd start. Check the connections inside the headlight as well - the heat from the bulb may be enabling a connection to earth, but, when it cools a little you lose the connection.

Of course, this assumes standard, factory wiring. If accessory lighting, e.g. a bullbar, has been added, then this is another likely cause.
