I have been out of the FORScan/ modding game for a couple of years now, but I would say if you added the correct sensors and rear harness, and IF you main harness was already populated with the correct wires, it would be very plausible that the needed FORScan changes could give you a working system. I'm sure that changes would need to be made in multiple locations though... BCM, IPC for sure

 

I am trying to see if anyone would have the values in the BCM and IPC that needed to be changed. I am able to enable the rear park aid in the APIM as-built

 

BCM: 726-46-02 xxxx xxx1 xxxx
IPC: 720-02-02 1xxx xxxx

This is what I have found using @Livnitup's spreadsheet

 

Cool thank you! I’m going to order the bumper, sensors and the new rear wiring harness and see if it will work.

 

Does anyone know the part number for the rear wiring harness for a 2019 f150 lariat with halogen taillights and rear park aid?

 

Hello everyone,

I started adding OEM LED/BLIS, ACC, and Reverse Distance Sensors back in 2020 by making additional writing harnesses during that project. I completed OEM LED/BLIS and only completed adding the parts/wiring for the ACC but had IDS / VCN issues so never completed that. Since I disabled it, I had no issues.

This past week I completed the Reverse Distance Sensor project by replacing the bumper, adding the sensors, making the final wiring harness at the bumper, and then the programming changes. This is where I started having issues getting it to work.
I enabled it using the following:
BCM 726-46-02 xxxx xxx1 xxxx
IPC 720-02-02 5xxx xxxx

The PAM module then showed up in Forscan so I programmed it:
736-01-01 3454 0009 xx
736-02-01 0400 0300 xx
736-03-01 0600 4200 xx
736-04-01 0000 2002 xx
736-05-01 1000 0000 xx

At that time, I started getting U2100-00-2B Initial Configuration Not Complete error. I had Forscan reset the module but that didn’t resolve anything.

I then tried another change on the APIM which cleared the PAM U2100-00-2B error but caused a C-CM C1001:08-2E error.

7D0-01-01 xAxxx xxxx xxxx
(My truck as built was 222A 0102 0028)
(Donor truck as built and what I used: 2A2A 0102 0030)

Since that error is the C-CM I added for ACC but not yet activated it, is this causing the problem adding Reverse Sensors or have I chosen the wrong configuration? The C-CM module is programmed for my VIN as I programmed it in 2020 and cross-checked it again today, VIN ASCII to HEX is correct.

Seems this should be simple but yet everything I try doesn’t work. When I made my wiring harness in 2020 for OEM LED/BLIS, I added the wires for reverse sensors and found that C316 was already wired for it and there were pigtails that I only had to butt splice my wires to which I found interesting but saved me from having to go from C316 engine compartment to the BCU. 😊

Any suggestions or options I can try to finish this?

 

I can't assist you with your questions, but I do have one for you. Do you think the old (non-sensor) bumper could be drilled to accept the sensors or is the hole a special shape?

 

I tried that and it is very hard steel and once you get the correct size hole, you will have to make 3 notches so the sensor brackets fit and do not rotate. That's why I quit for 3 years and finally purchased new bumpers. You also have to have another donor to measure the holes for the proper placement of the hole.
