Notes on control unit diagnosis

The KTS 560 / 590 is supplied with voltage either via
the power supply unit provided or the OBD interface in
the vehicle.
!
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.
i
On some vehicles, the ignition must be switched on
for power to be supplied via the OBD interface.
Connection to the diagnostic interface in the vehicle is
made by way of:
R
the OBD connection cable (fig. 6, item 2) or
R
the OBD connection cable and additionally a vehi-
cle-specific adapter cable (special accessory).
i
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.

Notes on control unit diagnosis can be found in the
Online Help for the diagnosis software.
3.6.3 Notes concerning the multimeter
and oscilloscope
Danger due to high voltage!
There is a risk of a potentially fatal voltage
when measuring high voltages.
¶
Always plug measurement cables into the
KTS modules first and then into the vehicle.
¶
Only use the measurement cables provided
(with contact protection).
¶
Connect measuring leads CH1- and CH2- as
close as possible to the object being mea-
sured.
¶
Use KTS modules only on the vehicle and
not for measuring voltage > 60 VDC, 30 VAC
or 42 VACpeak. Do not perform any mea-
surements on ignition systems.
¶
Do not lay unshielded measurement cables
close to sources of major interference such
as ignition cables.

Bluetooth USB adapter

The Bluetooth USB adapter included in the scope of deliv-
ery provides a radio link between KTS 560 / 590 and PC/
laptop.
!
It is not possible to operate any other item of Blue-
tooth hardware installed or plugged into the PC/
laptop, as this would interfere with data communica-
tion between the KTS module and the control unit.

Firmware update

After an update of ESI[tronic] 2.0, the firmware of the
KTS module is updated automatically when the control-
ler diagnosis is started.
To update the firmware, the KTS module is to be sup-
plied with voltage from the power supply unit provided
and connected to a PC/laptop by way of the USB con-
nection cable. Do not interrupt the USB connection
during the firmware update. The firmware update can
also be done using DDC (Diagnostic Device Configura-
tion) (see online help on DDC).
!
For a KTS 560 / 590, firmware updates must always
be performed using the USB connecting cable (not
by way of Bluetooth).
