Re: Adaptive Cruise Control Stop-go

So why is this difference?
  • a different control module. If so, what is the new part number. Can it be replaced on the older vehicles?
  • a different calibration (firmware) of the same control module. If so, will it be available to the older vehicles and eventually installed by the dealer? Apparently not.
It is being discussed here. So yeah it went quietly into production in July. And Milous says the older ones are not upgradable. And Scottina says the SRTs are not getting it either due to issues with the brakes. What makes it not upgradable? Is it cost prohibitive? Assuming it is a module or a set of modeules, do(es) the new one(s) have extra sensors and extra wires and our current wiring architecture (harnesses et. al.) don't allow it?

I would like it broken down to part numbers, costs and their location (could be in the transmission or could be in the engine compartment) before I believe the not upgradable statement. Think about it, if it fails on one of the older cars say next year what are they replacing with? Parts that were produced during a short run, the year before, for 4 months or a current equivalent part? Look at people getting radios replaced. They are not getting theirs replaced with units made in April 2013 with the April UConnect 13.12 or 13.15 version either but rather new units with uconnect firmware that the rest of us cannot Download.

I would more readily believe the SRT brembo story than the inability to upgrade.

We don't have all of the parts information at this moment but, it is a completely different system. I am sure some of the components are "shared" but I know there were changes to the ABS system. Slowing down to a low speed vs stopping completely and starting going again require a different type of brake/throttle interaction.

Milous explains some of the differences between the 3 systems here :Jeep Grand Cherokee WK2 - Cruise Control

I am sure it is "possible" to upgrade the system as they are still working with the same electrical architecture... However you may be looking at many thousands of dollars as it is probably numerous different components such as the ABS Module plus all of the programming. I don't think anyone would even want to touch that project due to the safety aspects.

Anyway, as you will see by Milous' descriptions of the other system components, there will likely be some good detail to come in the future.

Mine still waiting for shipping, but falls in this date range. Will Jeep do the software update before mine ships, or only if I have problems with this after I get the Jeep? - Which will be to late if I find out after it does not work, because that could mean an accident could occur.

Yes, most likely already done.

Re: Adaptive Cruise Control Stop-go

Sorry for thread resurrection!

Can anyone confirm or deny whether the 2015 SRT has the ACC with Stop feature? All the windows stickers I've seen for 2015 SRT's have "Adaptive Cruise Control with Stop" listed in standard features, the same as it's listed in Overlands with Tech Package, etc.

I haven't had the opportunity to test drive a '15 SRT yet and test the ACC for myself to see if it's been added and I can't find anyone else that's driven one either that can say for sure. Searching didn't turn up anything definitive.

Has anyone driven one and tested it out? Does it come to a complete stop or disengage >10MPH or whatever like before?

Thanks!

Re: Adaptive Cruise Control Stop-go

My 2014 diesel Summit has full working stop and go, so not sure why the 15 SRT wouldn't. It takes you to a complete stop and then accelerates by itself. The only limitation is it "times out" after around three seconds when completely stopped if the traffic hasn't begun to move again. This is for safety reasons of course.

Re: Adaptive Cruise Control Stop-go

Yeah that's the expected behavior on a non-SRT produced since late 2014. However, the SRT model apparently had issues with the Brembo brakes and therefore didn't have the full stop feature according to earlier posts in this thread. Wanted to confirm whether the 2015 SRT's had this resolved and now behave like your vehicle, or whether the 2015 SRT window stickers are all lying.

Re: Adaptive Cruise Control Stop-go

Yeah sorry guys I know this thread is in the regular WK2 (non-SRT) section, but I didn't want to create a whole new thread over there. I can though if it's creating confusion.
