Ok heres there story.

I tried to install my pioneer cd deck into my R32 GTS-t.

Me and a friend have done many stereo installations before.

When we first installed it, we blew a fuse that controlled the dashlights/tail lights.

Thats ok, we found the culprit wire(s) and sorted that out. No more fuses blew.

From then when I turned my car off, the doors would lock and when I clicked the button on the immobiliser, it would unlock and re-lock again.

So we ripped the whole deck out and detached everything from the wires. So now there is no wires connected to anything. When i turn my car off, it unlocks the doors. So i will hop out, lock the doors and go. Now when i return to my car, the immobiliser is armed, i click the button and it will unlock the doors and then lock straight away. The only way to get in, is to use the key.

When the immobiliser is not armhated, the doors will lock fine.

I have spent many many late nights and very many hours trying to solve this problem. We went through and pulled apart all the relays and tested them. We also swapped over the immobiliser with a friend (same type) and the problem was still there.

So our guess is, there is some wire(s) that were connected to the back of the stereo that either need to get power or need to be ground.

Another point is when you click the immobiliser button, it doesn't flash the parkers/tail lights like it use too.

Can anyone provide any help on this?

I have gone through most of the wiring and i know what most of the stereo wires do. However there are still wires there that we don't know the exact purpose for.

Any help would be greatly appreciated.

Yes, thats an option.

But those guys are ****ING DODGY!! and i mean very dodgy.

When we were going through my car, we found wires spliced and left like that. Things butchered here and there.

Guy i work with decided to get them to do his tint.

They ripped the back shelf out, and wrecked all the terminals. Also broke the shelf. At first they claimed they never touched the shelf, then they said, they just pulled it forward a little.

They're not someone i would like to trust or do business with.

Go through all the fuse's with a test light and ensure that they are all ok, next check that all earth wires to the alarm module are grounded

(HINT: some alarm installers use the radio as a ground)

some alarms use a seperate module for the door locks check this aswell.

When i fitted my alarm I used the wires going to the hazard switch did you plug it back in? as mine would not flash if the switch was not pluged in.

Thats all I can think of for now check all of the above and let us know how u went.

if u have more info that would help me tell u what to look 4!

Thanks for the offer rob, but i'm in WA :D

DAMQIK, Done just about all the checks you can think of.

I though i posted everything in the first post, please let me know what i missed out.

It doesn't have an alarm. Factory central locking and a Cyclops paralyser immobiliser.

I have a mate who was an auto elec for a few years, i'm trying to get him to have a look, but hes just been busy.

Soon as i sort the prob out, everyone will know!!

Thankyou everyone for your imput.

Ok so you checked the fuses under the dash? under the black cover under the bonnet & next to the battery? (there are 3 Fuse boxes in a r33)

PM me your email address and I will send the wireing diag 4 jpg pictures.

Thou I feel your prob is bad earth maybe run a new wire from earth to the module and the same for power+ if you have not yet tryed this.

is your cig lighter getting power?

Ok, I feel like a dick.

All along i knew the problem was easy, but just kept missing it. Mainly because each time we were working on it, it was between the hours of 10pm-3am.

There is a relay down in the kick panel with a "door lock timer" module, somebody has taken a wire off that relay and put it back on the wrong terminal, plus the immobiliser had a blown fuse.

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
