The contact numbers of the connector and the
socket numbers of VAG 1598/20 test box match
up page 01

.

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.

- If the specified value is not read, check fuses
and wiring connectors according to wiring
diagram and make necessary repairs.

Note:
If the check results and the voltage supply to the
Multi-function TR switch were OK, check wiring
