Test requirements:

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 1995 Volkswagen Jetta III, 1995 Volkswagen Golf III, 1995 Volkswagen Cabrio, 1994 Volkswagen Jetta III, and 1994 Volkswagen Golf III. However, it is still accessible from the selected car via links, so may be relevant.

Battery Positive Voltage (B+) OK
Fuses 14 (S14) and 21 (S21) OK
Transmission Ground (GND) connections OK:
- Ground (GND) connection located on left next to relay panel

Check Ground connections for corrosion and poor contact; repair if necessary.
Check Battery Ground (GND) strap as well as Ground (GND) strap between Battery and transmission.

NOTE:

Use the hand multimeter (Fluke 83, VAG 1526 or equivalent) for testing.
Use auxiliary cables from the VAG 1594 adapter kit, and the test box as specified, for connecting test equipment.

CAUTION: To avoid damaging the electronic components, select the appropriate function and measurement range on the test equipment before connecting the test leads.

NOTE:

The specified values are valid for ambient temperatures ranging from 0-40° C (32-104° F).
If the measured values differ from the specified values, determine the cause by using the wiring diagrams.
If the measured values differ only slightly from the specified values, clean the sockets and connectors of the test equipment and test leads, then repeat the test. Before replacing a particular component, test the wiring and connections and, particularly if specified values are below 10 ohms (10 Ω), repeat the resistance measurement.
