Interesting, thanks for sharing. I wonder if this software version can be read via Jscan ?Here's a copy of post 2190 on the Wrangler forum--same topic.
Concern is: Was the computer refreshed when the dealer did the steering gear change? The writer describes that his WASN'T. And this is how he knew:
" For those who didn't see an improvement or got worse after the new steering box, this might help:
SUMMARY: Dealer didn't update the steering pump software per the TSB, even though they said they did. To verify, get the specific "Options Report" printout from the dealership that shows either 5SY or 70F for the "Steering Pump & Gear Service Plan", don't trust the dealer service invoice that says they updated the software. Two different dealerships told me it was up to date, even my original steering gear replacement invoice said the software was updated, 3rd dealership showed me it WAS NOT updated on the "Options Report". All slop in the steering wheel is 100% gone after the 3rd dealership updated it to 70F. Finally drives like a Jeep now. I got suspicious because of lack of whining noise when the steering wheel is turned. The software update appears to increase the voltage on the steering pump, causing the whining sound (it isn't obnoxious, just an indicator the steering pump is on/active). In your case, you still might hear the whining noise with the old software, as some on other forums said they heard the whining noise before and after the software update. Point is, verify the software was updated via the options report print out, don't take their word for it.
DETAIL: It is very important to verify that they actually updated the steering pump software from 5SY to 70F via the Options Report not the dealer service invoice. In my case, the new cast iron steering box made some improvement, but not significant. Still had 2" of play, constantly correcting to keep it in lane. Very disappointed after seeing the success stories on this site. The dealership that replaced the steering box with the new cast iron version failed to update the EHPS (step 2 in TSB 08-074-20) and the steering pump software (steps 4 & 5) even though the invoice stated they updated the software. They also failed to replace the track bar for build dates before January 22 2019 (steps 12 & 13). After reading a few steering posts about a whining sound that people are hearing from the steering pump and I didn't hear any whining sound from mine, I started to wonder if they updated the software. I went back to the original dealer, they took it into the shop, said it was up to date. I went to another dealer, paid the hourly minimum charge, they too said it was up to date. I went to a 3rd dealership, and they hooked my JLU up to their service computer / DealerConnect and printed out an "Options Report" that the other two dealerships did not offer. It showed that the "Steering Pump and Gear Service Plan" was 5SY. F**KERS. I new the original dealership that replaced the steering box screwed up due to their attitude when I asked to verify. Note: See JD Powers surveys for the past 10+ years showing Jeep, Ram, Fiat dealers dead last in customer satisfaction. This third dealership updated to the correct steering box software, reprinted it, now it says 70F and ALL of the slop in steering is 100% gone. Point is, GET THE SPECIFIC PRINT OUT THAT SHOWS EITHER 5SY or 70F for the steering pump software. I did some research, but it looks like none of the menus in the radio will show this information. My only clue was the lack of a high pitched sound coming from the steering pump when the steering wheel is turned. You will need someone to turn your steering wheel back and forth while the JL is on and in park while you stand in front on the passenger side (right below the steering pump reservoir). I can now hear the whining sound from the steering pump, and ZERO slack in the steering wheel when driving at any speed."
Here's a link. Thanks to californiajeepn.
