How do you conclude BLD is on when on 2H?1 TCS monitors the amount of wheel spin of each of the driven wheels
2 A feature of the TCS is BLD which functions similarly to a LSD
3 BLD may remain enabled even if TCS and ESC are in reduced modes
4 When in Partial Off mode the TCS will be disabled except for the LS feature. Also the engine power reduction feature is disabled and EVS is reduced
5 When the ESC off button is held for 5 seconds while the vehicle is stopped the TC and SC will turn off
So it seems that BLD is active in 2Hi 4Hi 4Lo and when rear lockers are engaged. BLD should turn off when the ESC button is held for 5 sec - as well when both lockers are engaged.
In our exp we find that 4Hi with ESC on provides amazing traction on snow and ice covered roadways using stock KO2s. But uphill bends on ice can induce understeer which is controlled by letting off the go pedal. It seems the proper nannies kick in to get the JL back on the intended track. Has happened a couple times due to a touch more speed than the KO2s could handle.
Off-road what helps to get unstuck is to turn on both lockers and churn away. Even then that can be futile and shovels and ramps are required. Chains as a last resort before getting pulled out. Deep slush with ice under can be a wicked combo to overcome. Looks ok but once in it you are stuck up to your axle. Have seen 5+ completely stuck this season requiring a tow truck to extract.
And yeah if something like a Torsen was available vs clutch based - we would probs get that with a manual Ox up front. We do go off-road but our main use scenario with this JL is to get up resort mtn roads for skiing SB. For us Rubi FTW.
I've worked on cars with limited slip where the limited slip was not so limited. I don't know if the clutches wear or the springs weaken, but the result is that they can't offer much resistance to one side spinning freely.Well after 20-30k miles it won't matter cuz the POS LSD that Jeep uses will be toast.
In 2H put one rear tire on dry pavement, the other rear tire on ice. Apply some throttle and see what happens.How do you conclude BLD is on when on 2H?
1 ESC is turned on by default when you start the JLHow do you conclude BLD is on when on 2H?
That video could not have been done more poorly. For the first two tests he got the Jeep completely on the slope, then STOPPED, then gave it just enough power to spin a wheel, then gave up. Why? Why not show what it takes to get to the top in each setup? He never even gave the system a chance to work. The worst part is he never stopped in either attempt with both axles locked. He would have had wheelspin in every single scenario if he did it correctly.EDIT: For those unaware of JL options this vid shows what 4Lo gives you without lockers - then with rear locked (or sim to LSD locked up) - then with F+R locked. Front lockers are key to help pull you out or up.
I've gone up an incline like that but longer and a little steeper in my 2Dr Sport and didn't spin a tire. You don't need lockers to do something like this. (yea he got a run for it with the lockers )That video could not have been done more poorly.

That video doesn't show anything at all.Yeah not a perfect test by any stretch and anyone can criticize his vid. But super easy to replicate in snow, slush, or ice if you wanted to test yourself. At least he made a vid and posted it.
It definitely does.Just tested today in 2WD. Traction control on. Right side on frozen sand/gravel. Left side on hard packed snow/ice......stopped, gave it gas, TC lights flashing, engine power reduced not much spin on the ice. No prob moving.
TC Off......stomped gas, TC lights flashing, left wheel spinning and gradually slowed while accelerating......was moving the whole time and had no prob moving from the start, just more wheel spin at first without the engine power reduction. Looks to me like it works fine in 2WD.
