TROUBLE DIAGNOSIS Ð GENERAL DESCRIPTIONZD30DDTi
ECM Terminals and Reference Value (Cont'd)
EC-4043

Component Description
The mass air ¯ow (MAF) sensor is placed in the stream of intake
air. It measures the intake air ¯ow rate by measuring a part of the
entire intake air ¯ow. The mass air ¯ow sensor controls the tem-
perature of the hot wire to a certain amount. The heat generated
by the hot wire is reduced as the intake air ¯ows around it. The
more air, the greater the heat loss.
Therefore, the electric current supplied to hot wire is changed to
maintain the temperature of the hot wire as air ¯ow increases. The
ECM detects the air ¯ow by means of this current change.
CONSULT-II Reference Value in Data Monitor

Speci®cation data are reference values.

ECM Terminals and Reference Value
Speci®cation data are reference values, and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM's transistor. Use a ground other than ECM terminals, such as the ground.

4. Perform self-diagnosis by selecting the ªSelf-Diagnosisº.
+ Self-diagnosis subdivision screen will be shown and the opera-
tion enters the self-diagnosis mode.
+ A bar graph shown below the self-diagnosis subdivision screen
indicates progress of the diagnosis.
5. On the ªSELF-DIAGNOSISº screen, each unit name will be colored according to the diagnosis result, as follows.Green: No malfunctioning.
Yellow: Cannot be judged by self-diagnostic results.
Red: Unit is malfunctioning.
Gray: Diagnosis has not been done.
+ If several malfunctions are present in a unit, color of its switch
on the screen will be either red, yellow, or gray, determined by
the malfunction of the highest priority.
+ Lines between navigation unit and GPS antenna are green or
yellow based on diagnosis results.
+ Lines between control unit and units other than those above are
gray regardless of diagnosis results.
CAUTION:
+ Navigation Unit = NAVI control unit
+ Communication converter = Transfer unit
+ Satellite Switch = NAVI switch
6. Select a switch on the ªSELF-DIAGNOSISº screen and com- ments for the diagnosis results will be shown.
+ When the switch is green, the following comment will be
shown. ªSelf-Diagnosis was successful. Further diagnosis
and adjustments are recommended. Follow the
ªcon®rmation/adjustmentsº menu or refer to the service
manual.º
+ When the switch is yellow, the following comment will be
shown. ªConnection to the following unit is not responding.
See the service manual for further diagnosis.º
+ When the switch is red, the following comment will be
shown. ªNavigation Unit is abnormal.º

GPS ROM
malfunction
GPS RAM
malfunction Contents of ROM (or RAM) in GPS substrate are mal-
functioning.
+
Location detection accuracy of the navigation system
will deteriorate, depending on the malfunctioning area
in the memory, because GPS cannot make correct
positioning. (Location correction using GPS is not per-
formed.)
+
Perform self-diagnosis.
+ When the NAVI control unit is judged normal by self-
diagnosis, the symptom may be intermittent, caused
by strong radio interference.
GPS RTC
malfunction Clock IC in GPS substrate is malfunctioning.
+
Correct time may not be displayed.
+ After the power is turned on, the system always takes
some time until GPS positioning becomes possible.
(The GPS receiver starts positioning without re-col-
lecting the whole satellite information when it judged
the data stored in the receiver is correct.)
+ Correct time of error occurrence may not be stored in
the ªHistory of Errorsº.
+
Perform self-diagnosis.
+ When the NAVI control unit is judged normal by self-
diagnosis, the symptom may be intermittent, caused
by strong radio interference.
GPS antenna
disconnected Malfunctioning connection between GPS substrate in
NAVI control unit and GPS antenna.
+Navigation location detection performance has dete-
riorated. (Location correction using GPS is not per-
formed.)
+ GPS receiving status remains gray.
+
Perform self-diagnosis.
+ When connection between NAVI control unit and
GPS antenna is judged normal by self-diagnosis, the
symptom may be intermittent, caused by impact or
vibration.

GPS The power voltage supplied to the GPS circuit board has
decreased.
+Navigation location detection performance has dete-
riorated. (Location correction using GPS is not per-
formed.)
