VAG1598 Test Box, Connecting

VAG1598 Test Box, Connecting

- Switch off ignition.
- Remove A/C control head -E87- and disconnect all connectors, -A-, -B-, -C- and -D-.







- Connect VAG1598/11 and 12 adapter cables to corresponding connectors of the vehicle wiring harness (to -E87-).
- Connect VAG1598 test box to the respective adapter cable for performing measurements.

NOTE:
- Do not connect -E87-.
- When using VAG1598/12 adapter cable, the terminal assignment of the sockets is identical with the terminal assignment of -E87-.
- When using VAG1598/11 adapter cable, the terminal assignment of the sockets is not identical to the terminal assignment of -E87-.

Connector terminal assignment of VAG1598 test box with VAG1598/11 adapter cable

NOTE:
- The terminal assignment of VAG1598/11adapter cable connectors A and B is not identical to the terminal assignment of sockets on the VAG1598 test box.
- The terminal assignment of VAG1598/11 adapter cable terminal C is identical to the terminal assignment of sockets on the VAG1598 test box.
- The terminal assignment of VAG1598/12 adapter cable terminal D is identical to the terminal assignment of sockets on the VAG1598 test box
- As a result of splitting the connectors to A/C control head -E87- using two adapter cables (VAG1598/11 and 12), no ground connection exists for the test when VAG1598/11 adapter cable is connected. When performing various electrical tests, it is therefore necessary to use an external Ground source (vehicle body etc.) or a second VAG1598 test box (when adapter cable VAG1598/12 is connected, Ground exists at sockets 14 and 15).
