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 Freeze Frame #1: - EVENT\_TIME: 333751905 s (Sat Jun 14 19:08:53 2025) - Event tim - TOTAL\_DISTANCE: 64647 km - Total Distance - MODULE\_VOLTAGE: 11.8 V - Control Module Voltage - OUTDOOR\_TEMPERATURE: 17 °C - Outside temperature PWR\_MODE\_KEY: Ignition On - Power Mode Key State - PWR\_MODE\_QF: Power Mode OK - Power Mode Quality Factor - SS\_TRQ2: -0.5 Nm - Steering Shaft Torque 2 - ECU\_POWER\_SUPPLY: 12.0 V - ECU Power Supply Voltage - ECU \_INTERNAL\_TEMPERATURE: 20 °C - ECU Internal Temperature - VS3: 0.0 km/h - Vehicle Speed - DLA\_SED\_FDOB\_PID: 129 - DL\_SED\_FDOB\_PID - DLA\_NUM\_FDOC\_PID: -0.02 A - DL\_NUM\_FDOC\_PID - DLA\_NUM\_FDOD\_PID: 0.00 A - DL\_NUM\_FDOD\_FID - DLA\_NUM\_FDOE\_PID\_1: 0.0 Nm - DL\_NUM\_FDOE\_PID\_1 - DLA\_NUM\_FDOF\_PID\_1: 0 1/min - DL\_NUM\_FDOF\_PID\_1 - 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 ||7A5-01-01 |00AE | |7D0-01-01 |111F |89C0 |0355 | | |7D0-01-02 |4000 |001A | | | |7D0-02-01 |0455 |4B00 |007E | | |7D0-02-02 |00DB | | | | |7D0-03-01 |0000 |0000 |00DB | | |720-20-01 |FFFE |FFFF |43 | | |726-01-01 |5400 |8104 |A2AA | | |726-01-02 |0100 |0014 |0A4F | | |726-01-03 |4150 |1201 |10E5 | | |726-01-04 |0101 |0202 |053D | | |726-01-05 |1800 |000B |0B61 | | |726-01-06 |00C0 |0100 |00F5 | | |726-01-07 |0000 |7D00 |00B2 | | |726-01-08 |0000 |0000 |0036 | | |726-01-09 |0000 |0000 |0037 | | |726-01-10 |0000 |0000 |003E | | |726-02-01 |0004 |1E1E |70 | | |726-03-01 |0101 |33 | | | |726-04-01 |0100 |33 | | | |726-05-01 |0033 | | | | |726-06-01 |0034 | | | | |737-01-01 |0040 | | | | |737-02-01 |8000 |0000 |C1 | ---

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.
