Test table 

 

Notes on test table  

 The socket designations of adapter V.A.G 1598/21 are identical to the control 

module -J104 contact designations in wiring diagram.  

 Electrical Wiring Diagrams, Troubleshooting & Component Locations binder  

 If the readings obtained deviate from the specifications, carry out repair measure in 

the right-hand part of the table.  

 Electrical Wiring Diagrams, Troubleshooting & Component Locations binder  

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

 If the measured figures only deviate slightly from the specifications, clean sockets 

and connectors 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 

, repeat resistance check on the 

component.
