Notes on control unit diagnosis

KTS Truck is supplied with power by way of either the
adapter cable with battery clips provided, the connec-
ting cable for the cigarette lighter socket or the OBD
interface in the vehicle.
i
On some vehicles, the ignition must be switched on
for power to be supplied via the OBD interface.
Connection to the diagnostic connector in the vehicle is
made by using one of the following options:
R
The OBD diagnostic cable (fig.3, item 4)
R
OBD diagnostic cable together with vehicle-specific
adapter cable (fig. 3, item 3) (special accessory)
R
Universal adapter cable (fig. 3, item 5).
!
Make sure the OBD connection cable is properly
connected to the KTS Truck. Incorrect connection
could cause the pins of the plug to bend or break
off. Only use the OBD diagnostic cable contained in
the scope of delivery!
