So, no 360 Deg Cam.
How was the truck optioned?
Did it only come with (Rear Parking Aid) and you are wanting to (ADD) Front Parking Aid?
Can you find a (As-Built) On-Line truck that has (Both)?
If so, this is what you need to use as a (side by side) compare and go through (ALL) modules to see if there are any settings you are missing.
If all are correct, then you have something that is not wired or the IPMA may require a different part number.
Sorry but the manuals that I can see are not detailed on the variant options, such as - Parking Aid incorporates both Front & Rear and no varied option for only (Rear)
It lists a PAM module, but it is mounted under the dash and the upper dash has to be removed to access it.
Here are the varied options (Trim Level) Variance
1. Rear Parking Aid
2. Front & Rear Parking Aid
3. Front & Rear Parking Aid + Active Park Assist and Side Sensing Sensors (360 Deg Cam System)
So, for the US Version Rangers, without the 360 Deg Camera, there is a PAM module installed for options Rear Parking Aid and the Front & Rear Parking aid, so if you only have the Rear Parking Aid feature (OEM) then you should have a PAM
Now, I just did a As-Built search on a 2024 Ranger XLT, Rear Parking Aid, and it does not show module 736 either, but does show extra modules that the 5G does not have.
I deduced what they are except (1) Module 792 which may be fuel pump related
So, as I have previously said, the easiest way to do this is to find a truck that has exactly what you want to install without the 360 Deg Cam as side by side compare all settings to find exactly what needs changed.
I have a strong hunch you are missing wiring somewhere.
Here is a System Schematic of the Parking Aid System (W/O the 360 Deg Canera)
I have a feeling that although there is physical PAM module installed it may only be a communication (only) module, and the other modules need configured to be able to see (communicate) In & Out to it that you now have Front Parking Sensors installed.
Plus: With me now seeing that this is a - Primary LIN circuit.
Have you tried performing the:
New Lin Module Initialization with Forscan, this action MAY enable them as you have added new sensors and a switch to the circuit.
I checked varying trims for the 2024 Ranger (US Version) XLT / Lariat and Raptor with the Raptor having the 360 Camera. None of them list (736) as a module location.
However, in the manual it lists 736 as the module location for the PAM, so I am confused here and would need to actually find a 2024 to plug my scanner into to figure this out.
It should show up on the HS2-Can network.
