Electrical testing: Notes

WARNING: This page is about a different variant/trim than selected.

For testing use a Fluke 83 multimeter or equivalent.
The specified values are valid for an ambient temperature of 10-40 degrees C (50-104° F).
If measured values deviate from specified values, determine the malfunction using the appropriate wiring diagram.
If measured values deviate only slightly from specified values, clean the sockets and connectors of the test unit and test leads and repeat the test.
Before replacing components, check the respective wiring and connectors. Repeat resistance tests when values are below 10 ohms.
To connect test units, use test box VAG 1598/20.
The terminal numbers of the connector and the socket numbers of test box VAG 1598/20 must be uniform. See Figure .

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