Park Aid & Sensors Not Working

,

Right, im hoping someone can help

Ive recently bought a 2014 C-Max 2.0 diesel, automatic, which i was aware the above were not working.

Ive plugged in with forscan and im getting the following DTCs

Code: U0159 - Lost Communication With Parking Assist Control M

Status (-0A):

  • DTC Present at Time of Request
  • Malfunction Indicator Lamp is Off for this DTC

Module: Power Steering Control Module

I also have a similar message for the rear camera.

The original build sheet, show the car left the factory with above options.

It has the 10 sensor park aid.

When in forscan i cannot find build date in the AsBuilds for both the camera and the pam.

I have

7A5-01-01 00AE

&

720-02-01 FFFE FFFF 43

Am i right in thinking, that the BCM is not actually programmed to find the said modules?

Any help appreciated

Here is my build sheet

Looks like you may have a bad steering module.

I would guess the same. 7A5 is not your rear camera, it is your Navigation Display MFD5. Because you have a 2014, the camera has no own Module and is controlled by the BCM, by its own LIN line. A module doesn´t need to be programmed to only be find. Either a module on your HS-Can is defect or the wiring is messed up. The PAM has no own AsBuilt.
