Notes:
Use VAG1526A multimeter for the test. The
tables list which measures range needs to be
selected before taking each measurement.
The specified values are valid for an ambient
temperature of 0 to 40 C (32 to 104 F).

If the values obtained differ from the specified
values, determine the malfunction using the
applicable wiring diagram.
If the measured values only deviate slightly
from the specified values clean sockets and
connectors of testers and repeat test. Before
replacing a component, check wires and
connections. If the specified values are below
10 , repeat the resistance measurement on
the component.

The contact numbers of the connector and the
socket numbers of VAG 1598/20 test box match

.

To check the multi-function switch, it is not
necessary to connect test box VAG 1598/20
because first the connectors for the multi-
function switch are checked.

CAUTION!

To avoid permanent damage of electronic
components, select the appropriate
measuring range on tester before connecting
the measuring leads.
