The proper way is to remove the component in question, visually inspect each side of the connector for signs of contamination, inspect the terminal bearing surfaces of the flat wire circuits for splits, cracks, or other imperfections that could cause poor terminal contact, and insert the appropriate adapter from the J 42675 Flat Wire Probe Adapter Kit on the flat wire harness connector to test the circuit in question.
