Continuity checks with adapter set V.A.G 1594 A (bridging).
If the measured figures only deviate slightly from the specifications, clean sockets and
connectors of the testers and adapter cables (with contact spray G 000 700 04 ) and repeat
check. Before replacing components, check wiring and connections and also, particularly for
specifications of less than 10 , repeat resistance check on the component.
