Adding front parking sensors

Hello
I'm from Poland so that's why
sorry for my English :)
I bought a Jeep in the USA that was damaged in the front. While repairing it, I came across a bumper with parking sensors. I wonder if they can be activated.
The wiring harness connecting the cables to the first connector is intact. I also bought the appropriate PDC module. Only now I don't know how to connect. Please help. If anyone has one, please turn off the front sensor electrical diagram.
Jeep Cherokee 3.2 Limited 2020
Kind regards

Hi Arkadiusz,

I don't have parking assist in my 2014 TH but I think there is much more that you will need. The front bumper sensors and module are only part of the ParkSense system. There's also the back bumper and its sensors. In addition you would need the harness from the back bumper to the front. Then it would all need to be activated. If you only had the front bumper sensors active (and not the rear), I would think you will get errors. Again, I can't say for sure but here's some schematics.

You are great, thank you very much.
I have factory rear parking sensors. The original module does not have an output for the front sensors. I already bought one that has it. I have a computer program to configure the vehicle. I know that I need to run the harness between the parking sensors and the module. I still have two free wires that I didn't know where to connect. Thanks to the wiring diagram, I now know. I have to connect the wiring harness in the bumper because I don't know if the cables were installed by the factory. Even if they are there, I don't know where to look for them. I have already added a wiper sensor to this car (it works). I also have a camera on the windshield (requires adaptation) and ACC radar (requires adaptation). I have added all the necessary buttons.
Kind regards

Hi, 7 and 12 appear to be the signal wires for two of the six rear sensors. The rear sensors are 7,8,9,10,11 and 12. It is usual but according to the diagram, it looks like those two sensors are part of the front sensor connector. I am not certain why they are different. The only thing I can think of is that they are the first and last of the rear sensors. If so, they might be on both the right and left corners and in addition to the parking sensors, they also work for the blind spot detection system.

Hello
Following your suggestion, I checked the operation of the rear sensors live. There are 4 rear sensors. The blind spot sensors work like the other two, which gives a total of 6. All you need to do is connect the wires from the front sensors to the blind spot sensors and it should work. In a few days I will test it and share the results :). Once again, thank you very much!

Hello.
I studied the diagrams. My Cherokee has 4 rear parking sensors. There are 6 of them in cars before 2019. I simply won't plug in those sensors because they don't exist. If I do that, we'll see what happens. Unfortunately, the scheme for vintages after 2019 must be slightly different than before 2019.
best regards to you

Interesting, mine only shows one module. Then again there could be two since it also says they are in the front fascia.

Edit: hmmm Wonder if it will activate.
Wrangler Forum:
Having owned my JT for 1 year now I did not realize you can use the rear camera when driving. I was hauling stuff today and view was blocked and something told me to hit the camera button and voila. Image does not stay on for long but long enough to help with lane changes and to orient for incoming traffic on the interstate. Really cool stuff!!!

When you have both, they are on the same wiring harness on each side...
There's tons of modules in cars these days. :cool:
On my '19, you can turn on the back up camera from the 'Controls' menu in uConnect.

Hello,
Thank you all for your help. At this point, after visiting the Jeep service center, I managed to activate the adaptive cruise control, which I didn't have :). The camera on the windshield does not work yet, it could not be calibrated because there is an error. I think the error was caused by the wrong PDC module (PAM) that I bought to activate all the parking sensors. I have ordered another PDC module and will try to continue working soon. As for the parking sensors, I ran an additional beam from the front sensors and added and connected 2 additional sensors at the rear. I am adding a few photos to illustrate my work. I will let you know if there is any progress.

Hello Unfortunately, the sensors failed to activate. I tried on two different parking modules. In each case it shows an error and I can't clear it even programmatically. I think that the car's main computer does not have the appropriate settings and I am unable to change these settings. I'm giving up on parking sensors. I managed to activate ACC and the rain sensor. I will also try to run the camera on the windshield from the lane assistant. Kind regards A.M

Please help. I'm stubborn and I don't give up. I managed to add ACC to my jeep. The radar was used and I managed to install it in my Cherokee. However, the FFCM camera failed. The "incorrect vehicle configuration" error persists. Do you think that if a brand new camera is installed, it will work and the problem of incorrect vehicle configuration will disappear?
Best regards, A.M

I was able to boot all the systems I wanted. Semi-automatic parking, ACC and FCW.
1. "It was enough" to replace the front bumper with one with sensors, install 2 additional parking sensors in the rear bumper, replace the PDC module and the wiring harness in the bumper. The Jeep manufacturer was kind enough to wire the wiring harness from the front sensors to the PDC module. The plug is wrapped and lies next to the PDC module. Replacing the multi-button in the center console. The wiring diagram is different from before 2019.
2. With ACC, installing the radar, replacing the button on the steering wheel and calibrating it at the service center, and that's it
3. FCC, it's easiest to replace the windshield (I tried it on the old one, it's possible, but difficult). The electrical harness from the rear-view mirror in the cabin needs to be replaced. Install a brand new camera on the windshield. Then calibrate it and that's it 😊
Previously I managed to get the rain sensor working, almost the same work as with the FCC camera.
Best regards, A.M

I also wish to modify it. I was able to identify the parts but not able to get the cables and proper process to install them. I am having Jeep Cherokee 2019 which rear parking sensors only. I wish to add Front Radar for Adaptive cruise control, Front Lane assist camera, and Front Bumper parking sensors. So can you please help me to get the details for all Harness, modules and process? I will appreciate it. I have front Radar sensor (68441352AB) and Lane assist camera(68551095AC) part number. but I am not getting its harness and connection method for them.

I need you help to help me to get :
1. Radar wire Harness part number and connection location/diagram.
2. Front Lane assist camera wire Harness part number and connection location/diagram.
3. Front Facia Parking sensor wiring Harness part number and connection location/diagram.
4. Harness Connection for new buttons (68146856AC) in steering and dashboard panel (68158645ab).

Hi,

Finally I was able to complete all modifications successfully in my Jeep Cherokee 2019 3.2 Limited.
I have added Front Radar sensor, Lane assist camera, Rain sensor, front Parking sensor, Rear side sensors.

All Features like Adaptive cruise, normal cruise, keep lane assist, Lane departure warning, front collision warning and braking, Side distance warning, semi automatic parking including parallel parking, are working flawlessly. In short it’s Technology Package without Witech subscription under $1000.

All work done in UAE where there is no dealer support for American specs cars. Even no garage is aware about it or able to do it. All work done by own learning and taking help from different blogs site. But now feeling that this modification is worth.

If someone needs assistance, will happy to help.
