Vdc Turning Off

[30ONA]

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.

Probably brake fluid is low. As your brakes wear, you need more brake fluid. Lack of brake fluid triggers the vdc and slip lights, apparently

[Ben C34]

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?

Just for interest...

Have you changed or adjusted your tyres or wheels at all?

And did you check the brake fluid level?

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.

no change to tyres or wheels apart from taking them off when adjusting the park brake. Fluid level is fine.

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.

Check brake fluid level, check pad wear.

[The Max]

What superben said. Perfectly logical.

[30ONA]

So I topped up all the levels and no lights on since. Very weird symptoms from low brake fluid (not below the low mark) but seems to have worked.

[Ben C34]

Have you checked pad wear?

The fluid doesn't dissappear, it drops due to pad wear.

[30ONA]

Pads are ok, they must have just got to the point where the fluid was a little low. I have new Hawks ready to go on but need time to get the front rotors machined at the same time.
