Hi all. Today while driving normally on my way home my 'VDC off' , 'Slip' and the park brake light all came on on the dash. I pressed the VDC button a few times and no change.

I stopped the car turned off and on again and it went away. Then drove off and about 200m later they all came back on again. I left it as I was now on the motoray then the handbrake light went off. I stopped at the shop turned off went into the shop and them came out and started it again. Everything seemed find for the next 5k's home. On the way I tested the VDC on off and it was working. ie. when off the wheels spun when on they didn't.

Does anyone have any ideas what might cause this?

Is the handbrake related?

A few weeks ago I adjusted the hand brake and since then the hand brake light pops on sometimes after hard acceleration then goes off. But this VDC thing is new.

There's enough brake fluid in the system that as the pads wear it doesn't need topping up . If you top it up you have to sick it out when replacing pads.

So if the fluid is low, it has lost some somehow or the pads are totally screwed.

This can be a symptom of several different faults. I had a bad connector on the throttle pedal connector which gave the same warning lights and also severely limited power until I shut down the engine and restarted.

You need to get the codes read to determine the actual cause.

can you direct me to where or how I can read the codes?

A Nissan dealer or someone with a Consult3, some good mechanics may have a OBD3 reader which should be enough to check for error codes.

I will never want to take my car to Nissan, I've never had good dealings with car dealership workshops with any of my cars. Dealers are hopeless. Any one know any good workshops in brissy that can do a code check?

Try East Coast Customs at Geebung, I know they have all the gear to find the issue (and fix it).

I have had the VDC - Slip light issue many times. So many things can cause it, last time it was my steering wheel column slightly out of alignment, previously it was another sensor. If the code represents something that is not too bad (such as steering wheel column out of alignment), it seems to just turn on the slip and VDC off lights and just disables that system but the car drives normally. If it is a little more severe such as throttle sensor having a glitch or if the pedal position sensor is having a moment, the engine light plus the slip and VDC off lamps all come on and then the car goes into limp mode. This goes away sometimes if the car is turned on and off again. The park brake light might be the clue, I havn't seen that on at the same time as all the other lights.

Personally I have an Uprev flashed ROM on mine so I can plug in my laptop and see straight away what the issues are and clear the codes to temporarily fix the problem.

I backed off the adjusting nut on the foot brake pedal about half a turn and havn't had the problem since. I think maybe I over adjusted it to trigger the PB light and perhaps that led to the VDC.

I doubt a park brake light would cause a VDC system error.

I would still keep an eye on it.

well the VDC has not come on since, However there is a hill just before I get home (driving up) and frequently as I accelerate up the hill (>50% WOT) the hand brake light comes on, then as I back off the throttle it goes off again. If I drive up more moderatley it doesn't come on at all. So weird.

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
