C4 spacetourer 2018 Visual Parking Assistance INOP

[lgiovanni]

Hello everybody,

Since I bought this car, the 360º vision has been inoperative. The rear camera was stolen but, even after replacement, the system remains deactivated.

On the VPA module details page (image below), I saw strange information related to the SW version, calibration version and fabrication date. This is normal?

In your opinion, could this bad information be related to software problems (including the lack of sw loading in this module) or is it more likely related to a HW failure?

This is the list of faults related to this module:

I appreciate your support!

The faults all point to the calibration information being missing and this has to be done when the front camera is replaced for sure, but may apply to the system overall.

B122A 54 Front panoramic visual assistance camera fault: Calibration missing
B122B 54 Rear panoramic visual assistance camera fault: Calibration missing
B122C 54 Left-hand mirror parking assistance camera fault: Calibration missing
B122D 54 Right-hand mirror parking assistance camera fault: Calibration missing

So the first thing would be to recalibrate the camera system using Diagbox. Whether you will need any external equipment other than Diagbox I can't say. Or get your dealer to calibrate the system for you.

Good morning!

This problem was solved! Just to share...
The issue was in the Visual Parking Assistance control unit (PN 9806794080). I found a used part and after the replacement, all the cameras and 360º view back to work.

Of course, if the calibration procedure does not work, then it's likely to be the ECU which you have found. Thanks for the update.

Where is the location of parking assist ecu. I have the same problem. Thanks in advance

Greetings.

I changed the non-working front camera, but it lived for 3 turns and died:
B122A 49
B122A 13

I bought a block from 2016. But after installation, I get the same errors as in the old block.
B122A 54
B122B 54
B122C 54
B122D 54

Any thoughts?
How can they at least be calibrated in DiagBox?
