R34 GTT 1998

My indicators have just stopped working as I got to work today. Hazzard lights dont work either. However my alarm works just fine and unlocking/locking the car with the alarm lights them up.

Depressing the hazzard lights button I hear the relay click once under the steering wheel.

When the alarm ticks the indicators, it seems that it is slightly faster than usual... not a broken indicator though - Maybe it bypasses the relay? - i dont know...

I can't find the fuse for the indicators, but the fact the alarm runs them fine makes me think this is not an issue, unless the alarm bypasses the fuse and relay.

Any tips?

Thanks

I just removed the NILES IF332 OEM flasher relay and when I opened it it had burn spots on the plastic. It looks like a piece of metal broke off and shorted...

I placed a Tridon EP35 in to replace but it made no difference yet.

The relay still works though. I will check fuses as that seems likely.

Fuses are all good. Funnily enough, I armed the alarm, hit the hazzard button and the indicators came on and went off and now cease to function when the alarm is armed... but all fuses are still okay... wtf???!! Someone somewhere said something about an indicator controller... where/what is it?

hey mate sorry to sidetrack you but do you mind telling me where to get to the flasher relays? pic of the location would be great if possible.

I want to put in some LEDs for my rear indicators and i know that without a relay they will flash really fast - so i bought a relay switch thingy which will increase resistance, it's a plug type thing so no soldering necessary. any help would be much appreciated, sounds like you know where things go!

Pop your head up under the drivers footwell and you shouldn't see a whole lot... grab a light and look for a black relay on the door side of the steering column. To help you can flick on your indicators and you will hear and feel it clicking. Unplug it to confirm that its the correct one. :-)

Thanks mad. I did replace the head unit a few months ago. Could be likely.

I figured it could be a loose connection but the fact it still controls the relay made me look past it. Ill check on the weekend :-).

Has anyone got a wiring diagram inclusive of indicators? Ive seen a few but not one that details indicators.

Today I had another detailed look under the dash. I found a small fuse box going to the alarm with 2 fuses. a 5 amp fuse was blown. Replaced it with another 5 amp. It blew when alarm lit the indicators for 1/2 a second. Put in a 10 amp fuse now and the indicators work with the alarm!

The indicators still do not work with the stalk or hazard switch. I pulled out the hazard switch and connected it without the air vents. It makes a singular tick on the relay when depressed so it seems it still works. Still no indicators.

I removed the black box mounted in front of the flasher relay and check inside. All seemed okay. Just a smaller black box. No burns or smells.

What is in the brown relay thing?

I'm starting to think maybe the alarm is causing the issue...

Tested the new replacement relay. It does not work.

Tested old relay. working but low voltage. Cleaned connectors and bent copper to make better contact.

Working.

TLDR; Relay was partially faulty, so was new relay.

I can drive my car again! After putting back together the entire dash hahaha! I'm just happy I know what it is now.

I have pretty much exactly the same problem with my R34 GTR! Indicators and hazards do not work (no lights, no sound from flasher unit) but DOES work when I arm/dissarm my alarm system... hazard light is fully plugged in, fuse for indicators & hazard lights are fine.

I recently cut off some wires that go to the standard Japanese Sat Nav (as it is was unplugged) but after looking at it closer I noticed that the the hazard lights has 8 wires:

  • 3 to main wiring loom
  • 3 to a Sat Nav connector
  • 2 to the head deck wiring

So im wondering why would there would be connections from hazards to sat nav/head deck??

Cheers for any info/help guys!

This was in my GTT. I haven't checked out the wires going into the MFD (if that's what you're referring to) on my GTR.

Who knows. But if you cut it and then it doesn't work.......

This ^ If it stopped working exactly as you did this, check the pin out diagrams.

MFD Info: http://www.sau.com.au/forums/index.php?app=core&module=attach&section=attach&attach_id=166053 (from here: )

My alarm basically bypassed the standard relay and fuses for indicators. So that can mislead you.

Maybe check related fuses and then get a relay tester or another relay to test with.

But this is what trips me out...

  1. My Sat Nav & Head Unit were both already unplugged (so essentially the wires and pins arent touching or connected to anything right??)
  2. Why would there be wires going from Hazard lights to Sat Nav & Head Unit connections? Shouldnt they just go straight to the wiring loom?

Oh and Eps - No wires are MFD related.

Ah gotcha. Sorry, don't know anything about the Sat Nav units you describe. Didn't know they existed!

Check fuses in case one blew when you cut the wires. You might need to multimeter the wires you cut if it is still an elusive problem. I can't seem to find much on the wiring for the sat nav.

Check for voltage at relay and fuses and work your way back.

      What an awesome idea to fit the facelift Lamborghini Diablo headlights. They are a perfect fit!

      An update regarding the registration with the DVLA I sent off the paperwork the day after I collected the car from the port, two weeks later it was all returned with a letter explaining they have rejected the application. This was because the cheque was £20 short for the road tax (I used a price list I found online). Nevermind it is what it is, it was sent back to them the following day with a new cheque. Fast forward another 2 weeks or so, I called them for an update to be told it had been rejected. Yesterday (16th September) I received the documents back along with another letter, this time it was because I didn't put an X in one box on the V750 (personalised number plate certificate), which declared that I had the rights to the personalised number plate. Why this wasn't mentioned in the first rejection letter, I don't know, but it could have saved this headache. The documents were sent back today, so fingers crossed third times a charm and it'll FINALLY be registered on the road just in time for the bad weather (woohoo!) To cheer myself up I lowered the front 25mm, was sick of seeing it sit like a monster truck. No idea how much clearance I'll have getting on and off the driveway, I'll worry about that when I can actually drive it

      You're going to miss not worrying about rust in the strut towers like the Skyline shitboxes out there

      A few little updates that weren't filmed due to not taking long to do or not interesting enough for their own video. My new K&N Air Filter arrived, I went with an RU-4180 which matched the dimensions of the universal cone filter the car originally had.  The battery had gone flat, while that was charging I tidied up the spaghetti wiring at the bulk head and down the sides of the engine Next job was to swap the stereo The Kenwood harness had the female ISO plugs cut off and the male ISO plugs cut off the adaptor loom and joined with bullet connectors. I ordered in a repair loom through work and re-did it all. New Kenwood unit installed (Android Auto, DAB, Bluetooth, Reverse Camera) The bonnet/hood gas struts have been poor since collecting the car. I couldn't find any suitable replacements locally so took a chance on a pair from AliExpress.  The originals don't use a retaining clip to secure the cup onto the ball fixture, would explain why I struggled for 10-15mins trying to pry off the cups. The ball fixtures unscrew using a 12mm spanner, new ones are the same size. Sadly no photo of them fitted, you're not missing much lol The dished Momo steering wheel got replaced with my Momo Tuner, turns out I ordered counter sunk bolts for the horn trim ring (like they normally are for the steering wheel) instead of allen cap (flat seat)  A terrible photo of a Quaife style gear shift knob I've had stashed in my tool box for many years after purchasing the incorrect thread size (I can see a pattern emerging with ordering incorrect parts...) Also threw in a cup holder and a (empty) Boss Coffee can, because why not

      GT-R clearly the better choice! The 300 is certainly not insaly fast but has a decent amount of poke. Does a nice little drift around the corners with a decent amount of throttle. It's VERY predictable in a slide too.  Feels so progressive! People probably presume there's a 25 year old driving it based on my behaviour this week! 🤣
