Continuity checks with adapter set V.A.G 1594 A (bridging).

If the measured figures only deviate slightly from the specifications, clean sockets

and plugs 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.
