Car camera test station issue - need help

[krisbl]

Gentleman hi to everyone.

I am new here and someone of you might be able to help me with the issue that i have.

We have station for Car Camera Testing, testing is done thru a video receiver connected to a software - where camera during testing reads QR code and shows eitheer PASS or FAIL.

On the attached diagram you can see the complete circuit of the testing protocol.

Now the problem is, XC connector is wired at our facility. And often the workers missplace the wires places between pins 5 and 12 on the XC.

Both of the wires are ground, and even with missplaced wires the test passes - but on later stage when the camera got installed on the car shows problem.

I need to invent some solution that will prevent the camera to go ON if those two wires are missplaced on the connector - or to fail the test.



I need to sort this out, as i am in Maintenance there and my job depends on it.
AND TO BE HONEST HAVE NO IDEA WHAT TO DO.


THANK YOU IN ADVANCE,
KRIS




P.S. i have also posted the same thread on AAC, you can check the same https://forum.allaboutcircuits.com/threads/car-camera-test-station-issue.191389/

Can you show us a circuit of as much a possible? I still don't have a good idea of how the camera connects up.

It might help if you could show us on the picture of the circuit where the wires connect to.

The only solution I see it to make a dedicated cable tester, to verify the cable wiring before the cables are connected to the cameras.

Here is attached the photo of the assembly of the cable, once the mirror is assembled only the marked connector is visible and on the same the test is perofrmed.

So the grey connector consist of 4 wires, from which BK, YE, BN and RD.

Once the same is connected on the testing station and if the black and brown are replaced in their places the test again passes, which should fail in that case.
