Note: For test table

^ The socket designations of the VAG 1598 test box are identical to the contact designations of the ABS control module (w/EDL) -JI04- in the wiring diagram. Incorrect test procedures can cause damage to the system: do not make connections between any contacts other than those listed in the table

Refer to Wiring Diagrams
^ The specified values refer to the readings obtained on VAG 1526 tester and are not necessarily applicable for other test units.
^ If the readings obtained do not match the specifications, carry out the malfunction repair measures in the right-hand part of the table.

Refer to Wiring Diagrams,
^ If the specified values are achieved, also check wiring for intermittent loose contacts and short circuit to positive and Ground (GND). This applies especially to sporadic malfunctions.
^ Use VAG 1594 test leads for checking continuity (bridging leads).
^ If the measured figures only differs slightly from the specifications, clean the sockets and plugs of the testers and test leads (with contact spray G 000 700 04) and repeat the check. Before replacing components, check wiring and connections again, particularly if the specification calls for a resistance reading of less than 10 Ohms.
