Electrical test table

The socket designations of the VAG1598 test box are identical to the terminal designations of the ABS Control Module (w/EDL) -J104- in the wiring diagram. Incorrect test procedures can cause damage to the system. Do not make connections between any terminals other than those listed in the table.
See appropriate System Wiring Diagrams article.
The specified values refer to the readings on the multimeter and are not necessarily applicable for other test units.
If the measured values do not match the specifications, refer to the corrective actions on the right side of the table.
If the measured values match the specifications, also check wiring for intermittent loose terminals and short circuit to B+ and Ground (GND). This applies especially to sporadic malfunctions.
Use the VAG1594 connector kit for checking continuity (bridging leads).
If the measured values only differ slightly from the specifications, clean the sockets and harness connectors of the testers and adapter leads (with terminal spray G 000 700 04), and repeat the check. Before replacing components, check the wiring and connections again, particularly if the specification calls for a resistance reading of less than 10 ohm..
