i found a fault on the rear right parking sensor so i changed it but the fault still remains clearing the codes doesnt work i even cleaned the connector with contact cleaner before fitting a new sensor.

i ran tests all tests on ista for PDC it says the voltage is all correct, the sounder is making a noise when activated and everything else seems to be working according to ista.

funny thing was i couldnt run any pdc tests on inpa though for some reason. ive attached screenshots of the errors it says there is a short how do i test that though? i would rather test it if/where possible before i decide to replace the harness, just to confirm where the problem is

i have a multimeter so i can run tests with that if needed.

Don't know if this relates but when you have a short indicator
on Light's I believe you have to reset the fault with the software.
Once replacing the light.
Also did you try measuring for a short.
You are more likely to get a answer to this in the general forum.

i dont know how to test for a short exactly it might be different to another short.

i erased the codes still didnt fix the issue
