Does my truck have the B-LSD?

I have an SE 2x4 with the Big Tow package, no off road. According to the info Nissan publishes, it appears that the brake LSD is only available on 2x4's with the off road package. But it clearly says on my window sticker that it is on my truck as part of the big tow package. The owners manual confuses things further by saying the B-LSD could be represented by an idicator light on the dash that says B-LSD or SLIP. It also says that SLIP is an indicator for traction contol, part of the VDC system. There is no place for a B-LSD light on my dash, just the SLIP light. When I stepped on it pretty good yesterday, and got a chirp from one tire, then the truck hooked up and took off. The SLIP light was blinking, but power didn't feel like it was being cut. Was that the traction control, B-LSD in action, or both?

go around a corner flooring it. If you have an LSD then you'll leave two patches of rubber. If you don't have an LSD, then you'll only leave 1 (inside tire)

If you have to choose between me or the popo -- choose the popo.

That's true with a conventional LSD diff, but not with the Titans. Jeez Potroast, don't they miss your expert opinions and advice over on the Toyota boards??

Jason, do you have VDC on your truck?

jeez could you lose the hostility?

what the hell is the point of the Titan's LSD if it doesn't apply equal torque to each wheel?

the TITANS LSD uses braking to regain traction vs the mechanical posi type rear ends. if im wrong, tell me.

Your truck with VDC (from the online owner's manual)
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM (if so equipped)
When accelerating or driving on slippery surfaces,
the tires may spin or slide. With the Vehicle
Dynamic Control (VDC) system, sensors detect
these movements and control the braking and
engine output to help improve vehicle stability.
c When the vehicle dynamic control (VDC)
system is operating, the slip indicator in the
instrument panel blinks.
c When only the traction control system (TCS)
portion of the vehicle dynamic control system
is operating, the slip indicator will also
blink.
c If the slip indicator blinks, the road conditions
are slippery. Be sure to adjust your
speed and driving to these conditions. See
.Slip indicator light., and .Vehicle dynamic
control off indicator light. in the .Instruments
and controls. section.
c Indicator light
If malfunction occurs in the system,
the and indicator lights come
on in the instrument panel.
As long as these warning lights are on, the
traction control function is canceled.
[SIZE=2]The VDC system uses an Active Brake Limited
Slip (ABLS) system to improve vehicle traction.
[/SIZE]The ABLS system works when one of the driving
wheels is spinning on a slippery surface. The
ABLS system brakes the spinning wheel which
distributes the driving power to the other drive
wheel. If the vehicle is operated with the vehicle
dynamic control system off using the VDC OFF
switch, all VDC and ABLS functions will be
turned off.
< See note below
The ABS will still operate with the VDC
system off. If the ABLS system is activated, the
slip indicator light will blink and you may hear a
clunk noise and/or feel a pulsation in the brake
pedal. This is normal.

The part above that is in Blue is not accurate. Your paper owner's manual has new wording that changes this. Check your owner's manual for the correction.

In summary, the Titan does not have a limited slip rear.

Hey Potroast, Most of the people who have used their Active Brake Limited Slip, think that it is great. You may have read this thread:

Seems that traction is not a problem...considering that it is just a marketing ploy...

Limited slip differentials work by redirecting power to the wheel that has the most traction....ABLS works by redirecting power to the wheel that has the most traction.
It just does it in a different manner...

okay just a couple things... Nissan should call it "active brake power distribution" or some other name then.

a limited slip differential is what it is -- and what nissan is doing isn't it!

I'm not saying that nissan's doesn't increase traction -- it very well might... But it's just not an LSD.

Glad I know now, becauase I seriously would have bought a titan, not been able to get 2 patches of rubber, and I'd bring it back and tell em make it work.

Actually, even though it doesnt have a true "LSD," I still get two patches of black when I lay into it. So,whatever it does, it work similarly to a LSD.

Oh, It will leave two patches of rubber...if that is what you need a truck for. Once the ABLS sends the torque to the opposite wheel, the brake releases and both tires will spin just fine...I promise...
If by limited slip, you mean the old style that used clutches in the differential, then you are correct. If by limited slip, you define it by what it does, (redirecting torque to the wheel with the most traction) then it is no different.

I don't need to go around laying rubber in a titan. I think everybody misunderstood me. That's not why I need a fullsize truck... And owning a Tacoma Prerunner I know the cost of tires so I have no interest in killing em any time soon. However, every now and then it's nice to leave a trail of rubber when the situation calls for such.

and although my volvo does have an LSD and can leave a nice trail of rubber, it's fwd, so it's not exactly the prettiest to see burning out. I always thought it odd to watch the front tires burning out, lol.
