VAG 1598 Test box, connecting

Example: CIS-E Motronic control unit
- select the appropriate adaptor harness from the list (based on the connector you wish to connect to) for this example use adaptor harness VAG 1598/3
- connector adaptor harness VAG 1598/3 to main test box harness by joining the two rectangular connectors, then tighten via knobs on main harness connector

Note: The rectangular connector which is on every adaptor cable can only be installed one way. Examine the connector and you will see where the threaded connectors of the Test box harness attach to the adaptor connector.





- disconnect CIS-E Motronic control unit harness connector 1 from control unit 2
- connect test adaptor VAG 1598/3 male connector to control unit harness connector 1

Note: In this example the wiring up to the control unit is being checked statically, making it unnecessary to connect the control unit to the adaptor harness; however, for dynamic checks you will have to connect the control unit.
