I received the Z76 Recall letter for my 2021 Pacifica Hybrid on 10-22-22. When I called the dealer to schedule the warranty repair, the service advisor looked up the vehicle and said it did not need this update.No problem.
Z11 is a recall for the hybrid battery on 2017-2018 Hybrids that involves a software update and a charging evaluation that takes 2 days and has a minimum temperature requirement. Z76 is just a software update that prevents the ECH from getting permanently locked and thus needing replacement. Z76 is an update to the Hybrid Control Processor (HCP) and the Powertrain Control Module (PCM). Here is a link to the Z76 update procedure.
TSB 08-052-22
Did you also get a letter in the mail? If so it very clearly states that Z76 is just a software update.
During an service visit for a forward facing camera replacement due to a defect on 06/26/2021, I see on the invoice the dealer performed two other jobs unrelated to the camera replacement:
"Job #2: RRT 21-062 2021 RU PHEV HCP and AHCP update , Rapid response, Performed RRT21-062, flash updated HCP and AHCP modules,
Job #3: RRT 21-063 2021 RU PHEV PCM update, Rapid response, Performed RRT 21-063 flash updated PCM to latest software version."
I see the document linked by SKPacHy mentions " Rapid Service Update (RSU) 21-062 " which matches what is written on my invoice.
So did the dealer already fix the issue on the vehicle before the recall was issued?
Thanks
Quite possible. I had it done before the Campaign started as well. I believe the letter states that they still want you to take the vehicle back in to confirm it has been done.

The letter I received seems to have the standard language, and has the same text as the letter posted here: https://www.chrysler.com/universal/webselfservice/pdf/Z76.pdfQuite possible. I had it done before the Campaign started as well. I believe the letter states that they still want you to take the vehicle back in to confirm it has been done. Do you see that on your letter?
Ah the wording of my letter is slightly different as I am in Canada. So I guess it’s up to you whether you take it back in or not. If you don’t I’d just make sure your VIN is marked as completed by the dealer to make sure Chrysler stays happy. In my experience the software versions from the RSU and Z76 were the same.

I had ECH issues a year ago. The heater was replaced, but I did have several “encounters” with the CEL coming on, and even going off by itself. I had a few more service visits and the problem seemed to have gone away. But the weather also got warmer, and the EV performance seemed OK. This fall as the temperature dropped the ICE ran more than I expected, even to the extent that the battery did not deplete on a 100 km drive. A few days later the CEL came on. I then had the Z76 service performed, but the ICE still wants to run intermittently and unexpectedly despite a fully charged battery. I have the feeling that it is ambient temperature dependent.
The key with having Z76 done is all in the “Climate” section of the power flow screen. If you’re getting 7-8kW on a cold start then your ECH is working. The ICE is almost always going to run somewhat in the winter with the Pacifica. You can minimize it by turning HVAC off, but in Canadian cold that becomes a real bad idea quickly. The most important thing in cold winter is to use Scheduled Cabin Conditioning before your first outing, even if you are in a heated garage. That will give you the most range once you leave. But if it’s cold enough the ICE is likely going to start and run for a few minutes, then turn off and put you back into EV mode for a bit. Then the ICE will periodically cycle back on for maybe 30 seconds. But the ICE shouldn’t run so much that the battery isn’t getting depleted. I was driving around at -22C today, with the vast majority of time spent in EV mode and the Climate draw staying around 4-5kW.I had ECH issues a year ago.

I have not tried Cabin Conditioning before departure. I suspect that my Level 1 charger will not be able to provide enough power for the ECH (only about 1600 W from the outlet) so the ICE might still start up to avoid depleting the battery during the warmup.The key with having Z76 done is all in the “Climate” section of the power flow screen.

Read the manual. Scheduled Cabin Conditioning does not use the ICE, unlike remote starting, so it’s safe to use in a garage even. But if you are just using a L1 charger, the van will use some of the battery while heating. Most L2 setups allow SCC while keeping the battery fully charged. The van actually doesn’t even need to be plugged in for SCC to work, it just needs enough charge in the high voltage battery.I have not tried Cabin Conditioning before departure.

But SCC will get everything warmed up before you go requiring a lot less ICE use in cold weather. And the added benefit of a nice toasty vehicle without wasting a bunch of gas.
This "SCC" is just basically turning the car on, but not running, while it's plugged into the wall still.....right?
It turns on the electric heating system of the van and uses it to warm the cabin and potentially the battery as well. It doesn’t need to be plugged into the wall to operate, but there does have to be charge in the HV battery. SCC guarantees the ICE will not run so it’s safe to use in a garage or other enclosed space.This "SCC" is just basically turning the car on, but not running, while it's plugged into the wall still.....right?

But it's just pushing the start button twice, without touching the brake, and then you can set whatever you want for the HVAC settings?
The van is on and everything and in "run" mode, but not running/ready to drive yet until you press the start button again with your foot on the brake?
Just making sure I'm understanding this right. They call it "SCC", but you're not setting or scheduling anything per se.
No SCC is its own mode. It is programmed differently than the double start button trick. One of the biggest differences is that it works when not plugged in to anything. Whereas the double start button trick does not. You'll also notice that the HVAC controls are not active during SCC. So there are certainly some differences. We don't exactly know what they are. There could be differences in target battery temperature for example. But both modes can get you to a similar place.Gotcha.

And SCC can be scheduled through the e.Hybrid app on the UConnect display. I do that all the time. I set my departure time and the van wakes itself up and starts pre-heating for me. You can also set a weekly schedule if you leave the house at the same time every day during the week. It's super duper handy. It can also be scheduled through the UConnect smart phone app.

1. Yesterday I set Sched1 for 2:30 PM departure, and it worked just fine. The climate system started, was warm, and the vehicle ran on EV.
2. Today I tried to set Sched1 for 2:00 PM departure but could not get the day buttons to work. It seemed I could not cancel the Friday setting. I touched the Repeat button and all the day buttons became activatable, but I did not want Friday, but rather Saturday. If I recall I set Saturday and then toggled Friday, and then toggled Repeat. I Saved the changes
3. The Sched1 summary did not have an active indicator dot, but there was a text display that indicated 2 PM departure on Saturday. Despite this confusion, the climate control did start up before departure.
4. I go into the vehicle, pressed the brake and hit the ignition, and the ICE started. Maybe the climate system did not have enough time to warm up before departure.
In summary, the system seems a bit flaky, or maybe I am the flaky one. I will play with it some more.
BTW, any idea if Chrysler ever expects to change the driving history display to be correct wrt dates?
My 2022 Hybrid Ltd. has the same flakiness when trying to change a SCC from one date or time to another.. I do also have an issue with unable to schedule a charge when I come in off driving a considerable distance where the van is already using the ICE. If I wait a significant amount of time like 6-8 hours then I am immediately able to accomplish the scheduling. It seems like the software isn't working properly until the vehicle cools off?. Has done this from new and I now have about 3400KMs on the van with about 55% on ICE.I tried this and while it worked to warm up the car there were some quirks.

Hmmm....okay, well the past couple days I've just done the double start button then -- thinking that was it. 🤦♂️No SCC is its own mode.

So how do I get to this specific SCC mode?
And you scheduling this thru the Uconnect app.....you're paying for the subscription then?
(my 1 year trial just ended)
I just "discovered" a silly issue with the schedules... there are only 3 schedules in total!!! I thought there were 3 Charging AND 3 Climate schedules. Yes, you have to select Schedule 1, or 2, or 3; and then select Charging or Climate. But I really thought I had access to 6 schedules in total. That explains why after fooling around with Climate schedules my charging was all screwed up!!!My 2022 Hybrid Ltd. has the same flakiness when trying to change a SCC from one date or time to another..

Really, Chrysler, is there not enough memory in the computer to have a few more schedules?
I sometimes... well, often... get the feeling that companies do not pay enough attention to human factors in the design of the man/machine interface. Number One on that list of peeves is having a rotary gear selector on the console next to the radio volume control knob. It took awhile to get accustomed to NOT trying to change the radio volume with the BIG knob. Thank goodness there are interlocks on the gear selector. Another peeve is not being able to change the focus of the console display from the steering wheel. Yes, I can see some limited radio info on the instrument cluster, but sometimes I would just like to flip between the radio full display and the navigation full display. Having smaller windows on a custom Home Screen works, but it is not the same as full screen. Oh well, not everyone has the same likes and dislikes, so I will just accept an engineer's/programmer's decision on how to operate the vehicle.
Through the e.Hybrid app on the UConnect system in the vehicle. You have a 2021 so you go to Vehicle at the bottom, then go to Hybrid. It’ll bring you up to the Power Flow screen, then go to Schedules.Hmmm....okay, well the past couple days I've just done the double start button then -- thinking that was it. 🤦♂️
