Hi all,

Just wondering if any of you with 2011-current model Y61's have had problems with the VDC-off button after recent services? My 2014 Y61 was working perfectly well for the first 20,000 km, whenever I took it on sand in high range I would just turn off the VDC system and it would punch through super soft sections without a drama. However, since my recent service at 20,000 km (December) the VDC-off switch is now useless as the brake limited slip differential (BLSD) system overrides it all the time, resulting in total loss of forward momentum on soft sand beaches. The same problem exists in low range, where the VDC is supposed to be off by default. The only way I can override the problem is to engage the rear locker, which is only possible in low range (why Nissan set this up for low range use only, I don't know) and even then, you get the annoying alarm beeping when you do 20km/h +, which is always needed on soft sections of beach!

I understand that I can pull the ABS fuse and this should result in both the VDC and BLSD systems being turned off, but I really don't want to have to do this as the car was working perfectly well prior to the last service. I have had the car back to the dealer who said the system is working as it is intended to be and have no real interest in resolving the problem. They told me to call Nissan Australia who then told me to take it up with my dealer. Clearly they have no interest in resolving a problem unless their computers indicate that there is one.....

Has anyone on here experienced similar problems to this, and if so, have you managed to remedy them without pulling the ABS fuse when going off-road? I would also be extremely grateful if anyone has tips on how to allow use of the factory rear locker in high range and how to disconnect the annoying alarm that activates at 20 km/h +.

Thanks in advance.

Cheers,

Matt

Whats VDC?
Vehicle Dynamic Control aka Nissan's fancy word for ABS traction control combined with ESP (electronic stability program). BLSD is another fancy buzz word for the ignorant means its open diff with electronic traction control interfering meaning applying brake to slipping wheel. Brilliant technology in sand dunes....

This nanny state do gooders mandated crap in cars is making the whole on road safety even worse by dumbing down the drivers to the point that they won't be able to do anything except maybe buckle up and close the door.

Honestly, OP take it back to Nissan as the system clearly doesn't work properly. I do have a feeling that Nissan bozos have carried out software update on the system as a part of improvements to "fix" the VDC overide switch.

If it was mine I'd disconect that shyte immediately and learn how to drive good ole fashion way. Or re-run power to the system via overide switch so it can be disconnected properly when needed/on demmand. Same for diff lock, however not so sure I want to run with diff lock on at 80 km/h. Having it engaged at low range only is actually good idea but I'd agree limit of 20 km/h with buzzing is too low.

Anyway, knowing how Nissan likes to keep up its cars with latest technology I'm safe to assume that it still uses same diff lock system as in 2000 GU.

Diff lock switch is interconnected with diff lock control unit which makes sure that speed, 4WD mode and ABS signaling are adhered to.

Diff lock vacuum solenoid is double acting pin 1 is positive input from diff lock control unit which turns ON the actual solenoid and pin 2 is signal from diff lock switch to turn it OFF. (pin 3 and 4 are ground) bypassing diff lock control unit should be easy by running wire from the switch to the control unit directly to pin 1 on the solenoid instead.

That will get rid off everything including the buzzer(which can also be turned OFF by disconnecting sensor/indicator wire at the diff lock actuator/clutch), low range and speed limit. Only problem is now ABS/VDC/BLSD which you will need to turn OFF yourself either via a relay activated by your diff lock switch by breaking power supply to or after the fuse to the unit or installing another manual switch to do the same.....

All this of course will void your warranty and you are on your own should something get broken through missuse/mistake/forgetting etc .

Have a fun.

Cheers

Thanks heaps for this mate! I'll take it to a good auto sparky to ensure everything is done properly.

Cheers,

Wow your lucky. I can't even get my ABLS to work.
I've had VDC issues, but that was just showing as a fault. Never had it kick in whilst in low range

Just be glad you don't live in the USA, where the tweaks / disabling described above, put your vehicle in limp mode. Manufacturers are probably bringing that level of safety to Australia and NZ as we speak.

I have recently had the VDC and slip indicator lights come up on the dash since I had my car lifted. Only happens when your cruising down the hwy doing a 100kph for about 10 - 15 minutes then they come on no idea why but when you stop and turn the car off and restart it the lights are off and all normal until next time I'm driving down the hwy. Nissan will most likely be getting a call to fix under warranty.
