So, 23 4x4 XL, eLocker rear.
I know some Jeeps have electronic ONLY locking effect by braking one wheel to cause other to turn.
For say, low speed crossing a ditch where opposite wheels may be in the air.
Is something similar available in any of the selectable modes?

Seems like with all the valves and such in an antilock system everything is already there except the command.

If not, could I hijack such an effect with the Forscan?
Maybe a single wheel maintenance mode?

 

I believe you would have to replace the front carrier with an e-locker.
Not a true locker but...It would be easier to swap in a L/S torsen front carrier from a Raptor or Tremor.
FWIW the 2024 Ranger Raptor comes with front and rear lockers, but I doubt the front e-locker would fit an F150. I'll know for sure in few months when mine comes in.

 

Or you can diy by brake throttle modulation

 

My 2022 Lariat has exactly what you are asking, some called it E-LSD, Nissan called it ABLS, it's a Bosch ABS algorithm and works well. It also disappeared from F150's from 2015 to 2020, or I was just buying cheaper trucks (XLT's) that Ford thought not worth of the feature.

It works really well on my current truck, for street use, not much need to engage the locker, as the one wheel peel never gets out of hand.

It's worth noting that I am not familiar with the jeep system, but the current Ford system is not as "tight" as Toyota's ATRAC system, which simulates a locker fairly well, this is more like a clutch based limited slip type behaviour.

 

Better off going heavy on the gas, it requires a certain percentage slip to engage the ABS algorithm, if relying on the stock system.

 

Mark, hemi you get it.
(We are talking about the front [for a 4x4}, right? I have the rear $ E Locker.)
So, it is described in literature somewhere?
What does Ford call it?
Would it be in an otherwise base F150, do I have to select certain modes or 4x4 hi or lo, and do any lights activate when active - like ABS or Stability Control?
Is there a selection that I could accidentally turn it off - like Stability off or Sport on?

Where I live I cannot ever imagine needing rock crawling-type locking, but I do cross ditches regularly, so an occasional air wheel is very likely.

 

I’ve wheels many trucks with open front and rear diffs

in certain circumstances, if you risk losing traction, driving using left foot braking is the way to stop a spinning wheel, and move that power across the axle to the wheel with grip. With your left foot on the brake, set revs with right foot. Then gradually reduce the applied braking power.

 

I may be wrong, I have noticed the ABS system working when I'm on the gas, and the traction control is off, might actually be this: (from the 2022 Service manual)

Overview
The ABS and stability control systems are comprised of the following subsystems which assist the driver
in maintaining control of the vehicle:
l ABS
l EBD
l ESC
l Hill descent control
l Hill start assist
l RSC
l Selectable drive modes
l Side-wind stabilization
l Supports adaptive cruise control
l Supports collision avoidance
l Traction control
l Trail control
l Trailer sway control
l Torque vectoring control

Torque Vectoring Control
The ABS module continuously monitors the vehicle motion relative to the intended course. This is done
by using sensors to compare the steering wheel input, the yaw rate sensor input, the lateral acceleration
sensor input and the longitudinal acceleration sensor input with that of the actual vehicle motion.
Steering wheel angle information is calculated by the PSCM and is sent to the ABS module over the FDCAN
. Vehicle roll rate, yaw rate, lateral acceleration and longitudinal acceleration information are sent
to the ABS module from the RCM also over the HS-CAN2 through the GWM . If the ABS module
determines the vehicle is experiencing over-steer or under-steer, the module sends a torque vectoring
control message over the FD-CAN . The GWM relays this message to the PCM over the FD-CAN and
to the IPC over the HS-CAN3 . When the PCM receives this message, it assists with torque vectoring
control by adjusting engine timing and decreasing fuel injector pulses. When the IPC receives this
message, it flashes the stability-traction control indicator (sliding car icon). The ABS module continues
to monitor the sensor inputs while the PCM assists with torque vectoring control. If the ABS module
determines PCM intervention is insufficient to control the stability event, the ABS module modulates
brake pressure to the appropriate brake caliper(s) by opening and closing the appropriate solenoid valves
inside the HCU while the hydraulic pump motor is activated. Once the vehicle instability has been
corrected, the ABS module returns the solenoid valves in the HCU to their normal position, deactivates
the hydraulic pump motor and sends another message over the FD-CAN indicating the event has ended.
The PCM returns engine timing and fuel injectors to normal operation and the IPC extinguishes the
sliding car icon.
