HOW TO DETECT THE DOOR SILL PLATE COVERS FAILURE

Defects of the components are well seen with the naked eye. Cracks, scratches, warpage indicate that it's time for replacement. You need as well to inspect if the covers are reliably attached. If they got unglued or clips are damaged, repair the plates or install new components.

If the door sill covers are illuminated, you will need a multimeter to inspect them. You have to connect the multimeter to the power supply wire terminals and measure the voltage when switching on the lighting. If the power is not supplied to the LED, the cover is defective.
