Using VAG 1598/18 the wiring can be checked according to the wiring diagram.


CAUTION!
In order to avoid interference with electronic components, switch to the correct test range on the multimeter before connecting the test leads.


NOTE:
- For testing use a Fluke 83 multimeter or equivalent with auxiliary wiring from VAG 1594.
- The specified values are valid for an ambient temperature from 0 °C - 40 °C (50 - 104 °F).
- If measured values differ from the specified values, determine the malfunction using the appropriate wiring diagram.
- If measured values differ only slightly from the specified values, clean the sockets and connectors of the testers and test leads and repeat the test. Before replacing the particular components, test wiring and connections and, particularly if specified values are below 10 Ohms, repeat resistance measurement on the component.
