From the ECU tools. First select the ECU > CEM then in the drop down you have commands to send to ECU. You'll see there SW version.
You mentioned in the other thread that if you configure regular front and rear park assist, you get only three codes for the three of the front sensors.
Left front inner > This is the driver side on the black trim in front of the radiator.
Left front outer > This is the driver side on the fog light bezel.
right front inner > This is the passenger side on the black trim in front of the radiator.
So, you have only 1 working one, passenger side on the fog light trim.
So, start from the basics. Try to make it work with regular front and rear park assist. (8 sensors in total)
Remove the sensors from the sides both rear and front. Leave total 8 sensors Just incase if any of them shorts.
Set the configuration to front and rear parking sensors. Reset the CEM and clear all the codes.
Then start the car and check for DTCs. Assuming you get the same DTCs above. Clear the DTCs. If you do not clear, it may give you false results.
Take the sensor passenger side on the fog light trim (did not give DTC) and replace it with the one on the driver side fog light trim.
start the car and then check the DTCs.
If the DTC moves, you know the sensor is faulty and you can check with of the two side sensors.
If the DTC does not move,
You have three possibilities.
1) CEM is faulty > Less likely.
2) You have a short on the wiring. > possible
3) The sensor's PIN1 and PIN 3 are switched. > most likely (if you did the whole bumper wire yourself)
Did you buy a front bumper harness or did you do the wiring yourself?
FYI, you should not be able to connect a front sensor to the rear harness.

With the fog lights I left them without cornering lights and it still doesn't work.
I bought the car 1 month ago, I don't know if it has any updates at all.
Where can I see the SW version?
