- If the readings obtained deviate from the specifications, carry out repair measure in the right-hand part of the table.
- 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 ohms, repeat resistance check on the component.
