5 . Set the ignition switch and the tester main switch
to ON. Read the engine coolant temperature value
on the diagnostic tester DS-21 or on the OBD II
general scanning device.
Is the value measured equal to 140° C or higher?:
If SO: the wire between the ECT sensor and the
electronic control unit is interrupted. Repair or re-
place the cable harness.
If NOT (EURO 3): check the connector connection
and the electronic control unit terminals. If this is
in order, replace the engine electronic control unit
(see the relevant section).
If NOT (EURO 4): the DRACO or the cable har-
ness connecting with the ECU is interrupted. Fix
the cable harness or replace the DRACO.
Check cable harnesses downstream and up-
stream the DRACO and on the DRACO itself in the
following order
•
Test the cable harness in the EFI ECU
control unit connecting the special tool
to the DRACO connectors on the con-
trol unit side.
•
Check the DRACO works properly: dis-
connect the DRACO cable harness on
the device side of the vehicle, connect
the special tool to the relevant connec-
tors and follow the procedure of Step 3
from the start. If no failures are detec-
ted, the problem is in the DRACO con-
trol unit which must be replaced.
•
Test the cable harness in the vehicle
connecting the special tool to the DRA-
CO connectors on the device side.
If all the tests do not work, go back to Step 2 .
