Parking sensors retrofit status / update

[Stbentoak]

And now I find it interesting that they're shipping new Tahoe's with the heated steering wheel and rear park assist and removing the wireless charger from the vehicle with a $50 credit that isn't eligible for a future retrofit.

So we've already spent our $60k+ and don't get two key features of the vehicle BUT people who haven't paid GM yet are getting the chip? Something doesn't add up here. The sonar I can live without, to be honest--especially with the surround camera view. And I will GLADLY forfeit my wireless charger for my heated steering wheel LOL

Why does this surprise you? They already have your money. There is no urgency to make you whole….

And there's not a damn thing we can do about it... Classic

Has anyone heard anything other than that they don’t have parking sensors? I’ve reached out to GM and they say they will send a letter when they’re available. A year later and the wait goes on.

This thread provides a glimmer of hope that the retrofit is coming soon. Read post #17 and beyond where a GM employee mentions that there’s a pilot program rolling out to GM employees for the retrofit and after that it goes out to the general public.

Front and Rear Parking Sensor Retrofit

Has anyone who didn’t get the front and rear parking sensors had their dealership contact them to get them retrofitted yet? Had the car for over 2 months and nothing yet. Seems like it’s taking a long time especially since all cars coming off the assembly line are getting them again

Promising. Maybe within the next 6 months? .... I'm avoiding going to the dealership to get my washer fluid pump fixed but I'll definitely go in if I can get the sensor retrofit.

Your washer fluid pump failed too? Hm. I have a oil change due soon so plan on getting mine fixed but now wonder how common this problem is.

this is odd! the "2022 - Yukon Electrical Body Builder Manual" says that :
The parking assist system is made up of the following
components:
• K182 Parking Assist Control Module
• B306 Parking Assist Alarm Sensors
• Infotainment system

if the module, sensors and of course the infotainment systems are not missing, then it should be working, unless an internal component inside one of these 3 components is missing!

I figured out what’s missing.

After looking at the wiring diagrams and reading the function overview on the GM Upfitter site, it seemed like the only thing that could be missing was the module mounted on the passenger side D-pillar.

Mine has it installed as shown in a previous post, but it dawned on me that maybe it’s just the box, but no circuit board. I pulled out the interior trim and got the module out. I released the tabs on the housing holding in the circuit board and this is what I found.

Now I’m no electrical engineer but do you see what’s missing from this PCB? Chips!!! I see at least two locations where surface mount chips should be soldered.

They’ll probably remove this incomplete module when it gets retrofit, send them back to Bosch to get reworked and then put them back on the production line.

I guess this is the case, GM fitted uncomplete module.
however bought the P/N 85131832 and when fitted, got the message "Service
Driver Assist System"
so it has to be programmed to the car VIN. so you'd need a programming interface plus 45$ for ACDelco DTS
and yes the original part is missing all ICs.

Well, that takes care of that. Good to know it’s not plug and play. It’s also a bummer that this module is in a place which requires removal of so much trim. If it was on the opposite side, they could pop off the fuse block/jack cover and have it replaced in a minute when the dealer does the retrofit.

Just a little update;

tried to reprogram the module and got error E4398 – No Calibration Data
which is the result of a missing or incomplete data record. so GM has not put the data in the Service Programming System (SPS-2) yet.

Gm won't do the retrofit anytime soon and won't let us fix it
