t
| The test box -VAG 1598/42- has 105 sockets. The engine control unit may be connected using 2 different adapter cables. |
t
| The engine control unit is connected to the wiring harness of the vehicle via a 60-pin and 94-pin connector. |
t
| The test box -VAG 1598/42- is designed so it can be connected both to the wiring harness for the engine control unit and to the engine control unit itself at the same time. The advantage of this is that the engine control electronics can operate while the test box is connected (for example when measuring signals while the engine is working). |
t
| The relevant test procedure will state whether it is necessary to also connect engine control unit to test box. |
t
| For the connection of measurement equipment (for example voltage tester -VAG 1527 B-, hand-held multimeter -VAG 1526 A-, etc.) always use the auxiliary measurement set -VAG 1594 A-. |
In order to separate the engine control unit connectors from the engine, the engine control unit must be separated from the engine → Chapter. |
WARNING To avoid the destruction of the electronic components, before connecting the measurement cables, the correct measurement range must be selected and the test conditions must be complied with. |
