Notes on control unit diagnosis

If a test step involves starting the engine, the
battery voltage may drop to such an extent that
supply via the vehicle is no longer guaranteed.
In such cases it may be necessary to run the
KTS 560 / 590 by way of the power supply unit.
On some vehicles, the ignition must be switched on
for power to be supplied via the OBD interface.
the OBD connection cable (fig. 6, item 2) or
the OBD connection cable and additionally a
vehicle-specific adapter cable (special accessory).
KTS 560 / 590 is ready for use if an acoustic signal
is heard after making a connection with the motor
vehicle's diagnostic interface.
Make sure the OBD connection cable is connected
to the KTS modules in the correct position.
Incorrect connection could cause the pins of
the plug to bend or break off. Use only the OBD
connection cable contained in the scope of
delivery.
