Notes on test table 

z

The socket designations of adapter V.A.G 1598/36 are identical to the ABS control module (w/EDL) -
J104- contact designations in wiring diagram.  

z

If the readings obtained deviate from the specifications, carry out malfunction repair measure in the right-
hand part of the table. 

See  

z

Continuity checks with adapter set V.A.G 1594 A (bridging).  

z

If the measured figures only deviate slightly from the specifications, clean sockets and plugs of the testers 
and adapter cables (with contact spray G 000 700 04) and repeat check. Before replacing components, 
check wiring and connections and also, particularly for specifications of less than 10 ohm, repeat 
resistance check on the component.
