Gearbox: Electrical test

Special tools, testers and aids required
♦ Hand-held multimeter (e.g. V.A.G 1526 A)
♦ Auxiliary cable (e.g. V.A.G 1594)
♦ Test box (e.g. V.A.G 1598/18)
Test requirements:
l Voltage supply of vehicle o.k.
l Fuses o.k.
⇒ „Current Flow Diagrams, Electrical Fault
Finding and Fitting Locations“ binder
l Earth connections and earth point for gearbox
and gearbox control unit o.k.
⇒ „Current Flow Diagrams, Electrical Fault
Finding and Fitting Locations“ binder
- Inspect battery earth strap and earth strap
between battery and gearbox.
Important!
Switch on the relevant range at the tester before
connecting the test cables in order to avoid dam-
aging the electronic components.
♦ The specified values stated apply to an am-
bient temperature of 0 ... 40 °C.
♦ If the readouts obtained differ from the speci-
fications, determine fault on the basis of cur-
rent flow diagram.
⇒ „Current Flow Diagrams, Electrical Fault
Finding and Fitting Locations“ binder
♦ If the readouts obtained differ only slightly
from the specifications, clean contacts and
connectors of the test equipment and test
cables, and repeat test. Inspect the cables
and connections before replacing any com-
ponents. It is particularly important to repeat
the resistance measurement at the compo-
nent if the specification is less than 10 .
