The next unit is activated with each pressing of the key  “ 1 ”.
When pressing key  “ 3 ” the working instructions for canceling the malfunctioning cause of

the unit will be displayed and by pressing the key

 

 “ > ” the unit is reselected.

When pressing key  “ N ”during the activation of a unit, one returns to the checking sub-range

of the activation units.

In case of choosing the displaying of the real values of the measured checking two options for

real values selection will be displayed by pressing the key “ 2 ”:

- press key   “ 1 ” for selecting three parameters wit real values;
- press key  “ 2  ”

 

for exploring one parameter in a raw, starting with the first one.

- press key  “ > ” for selecting the next item of the list;
- press key “ N ” for returning to the sub-menu displaying the real values of the measured

elements.

Further information concerning the KTS 300 Tester are provided in the Instructions Book

“Pocket – System Tester KTS 300 Bosch”.

D

ISMO UNTING

Disconnecting of the battery terminal (-).
Disconnecting of the connector coupling the control unit to the control cables of the fuel

injection, as follows:

- the lock (1) is pulled arrow-sense;
- the connector is turned around point (2), arrow-sense (a), until its disconnection;
- the fixing screws of the electronic control unit on the right bumper column are dismounted.

R

EMOUNTING

Reverse the above mentioned operations.
Functioning tests (system testing).

WARNING !

When manipulating the electronic control unit, you should avoid mechanic shocks

and above 85 °C heating. You should also avoid any dust or other impurities on the
contacts of the control unit and of the connector; these could lead to signal errors.

The control unit should be connected or disconnected only after battery terminal (-

) disconnection.

ISMO UNTING

The connector is disconnected from the

rotation sensor by  pressing the fuse  (1),
arrow-sense and  then  it  is  dismounted.

The fixing screw of the sensor on the clutch

case is  dismounted.

EMOUNTING

Reverse the above mentioned operations.
Functioning tests (testing of the rotation sensor functioning).

WARNING: In order to avoid its damaging, the sensor should be placed in the clutch

case by pushing, not by hammering.

The tightening strength of the fixing screw = 8 ± 2 Nm.
