Have the tech look at step 11 on 24B56.

Will do! Thank you!

Does this apply for 12 inch center display screens as well?

No. It's only for the larger screens.

Yours is normal. The only issue is on 22's where the dealer didn't follow directions so they're left with the black box around the image until it's either fixed in FDRS or FORScan.

Yep, just dropped mine off yesterday to have the 360 postage stamp fixed.

Power steering module gets reprogrammed as well. I noticed it almost immediately when I picked it up. Less of a center feel and the camber of the road pulls the steering differently. I’m sure I’ll get used to it but I liked the old power steering boost level.
I wonder if the FORScan gurus can find a setting to tweak???

I’m still stuck on the new power steering feel after getting this update. I’m really not liking how loose it feels and how bumps in the road seem to pull the wheel away from center unlike how it was before. Is this experience similar to others? I also had the front control arm bolt/nut recall looked at the same time and the dealer said it was fine, so I’m assuming the new steering feel is from the reprogrammed modules in the front sensor CSP.

This is what I’m experiencing.
I’ve seen on F150 ICE forums about a few settings in the PS Module that can be changed with FORScan, one specifically dealing with return to center. I have not played with this and haven’t researched fully yet.

However, I think the problem is not that the update trashed the LVB capacity (my dealer says they always use a power supply backup in flash programming, but the CSR couldn't tell me how big a rig!). If I read the LVB voltage across the jump points in the frunk, I get readings like 12.57V, 12.64V at 65F to 72F. That suggests the LVB is charged to 80% to 90%. Seems more likely that the update screwed up the BMS or its communication with other modules. Rather than trying to cure it myself by disconnecting the negative LVB terminal, etc., I'm just going to bring it back to the dealer this coming Thursday and let them figure it out.

It turns out that my LVB was trashed by the 24B56 parking sensor update. Although the cell voltage could be raised by prolonged charging, the battery capacity had been trashed, as revealed by the low-capacity ratings that Car Scanner was giving me after the update. The dealer replaced my LVB at no charge, and everything's back to normal.

The other symptom of an almost-dead LVB after the update was that if my frunk were left open for any length of time, the truck would go into Battery Saver Mode (after trying and failing to charge up the LVB), and then I'd have to manually close the frunk to shut it. FordPass wouldn't work remotely to shut the frunk without starting the truck. The nice thing about all this was that I could still start the truck even when Car Scanner said I still had only a few percent LVB capacity left. So, hopefully, that means a failing LVB is unlikely to catch anyone by surprise and strand them. If it's like my situation, one will get lots of Battery Saver mode alerts as the LVB gets on its last legs.

So I feel like I’m taking crazy pills but the weird loose steering feel has seemingly corrected itself for me after about a week or two of driving. It was definitely different right after the front sensor CSP programming was done and I hated it. But I’ve noticed it is back to the normal firm steering feel. So either I’m losing my mind or there’s some kind of relearning process that happens with the steering after this particular CSP is done.

I kinda miss the heavier steering feel

Experiencing this as well and has significantly changed the driving feel. The ratio of the steering has changed, giving it a much lighter, faster, and less steady feel, especially at lower speeds. The weight of the steer was definitely heavier and less touchy before, strongly preferred it.

Before reading these posts, wasn't sure what to attribute the change to. Just picked up the truck from a service appointment that included a tire rotation, the recall work on the upper control arm ball joint, work behind the steering column, as well as the recall software update for the front parking sensors. Thought it could be any one of the above.

Scheduled for another appointment this week to address it, but doubting now that it can be remedied.

Had a moment like this, but it was because of low morning temps (around 30 degrees), cold slowed the speed of the steering. Got back in the truck at lunch (around 75 degrees) and it was the same loose steering. The warmer the temps, the greater the perceived loose feeling in the steering.

And I feel like the lane centering isn’t as great as it was before. Anyone else?

My lane centering doesn’t seem to be affected as far as I can tell. It has been colder here in MA though so when it warms up again I’ll pay attention to the steering feel and see if that changes anything.

Was pulling to the left when I left the dealership. Seemed to improve and is less of an issue right now than the change in steering feel.

Here's hoping you're right and I'm wrong!

I’ve had a similar experience. I chalked it up to the freshly rotated tires wearing in a bit, but now that you mention it it seems possible the steering feel is changing a bit over time?

@KHines, @MountainAlive, @Cvh8601 -

Following up here to see if y'all are continuing to experience the faster steering post update? In my case, it was coupled with a bad alignment that forced the issue and had to take the truck back in (different service department). After correcting the alignment, a steering calibration was also performed, but unfortunately failed to fix the faster steering. Scheduled for service again next week to make another attempt at fixing it.

Any feedback/advice would be appreciated. Wish I was more optimistic about it being resolved.
