CRUISE CONTROL SYSTEM (DIAGNOSTICS)
32 Out of vehicle speed of
cruise control operation
•Controlled vehicle speed decreased under
the limit during cruising.
•Set operation was performed at vehicle
speed unavailable for setting.
•Resume operation was performed with-
out memorized vehicle speed.
This DTC is displayed, though the vehicle
speed is increased to the speed available for
cruise set and set operation was performed
again.
nostic Procedure with Diagnostic Trouble
Code (DTC).>
33 WAIT is prohibited after
operating accelerator
pedal.
Controlled vehicle speed increased above
the limit during cruising.
This DTC is displayed when driving at higher
speed than appropriate cruise control
speed. In this case, lower the vehicle speed
to the speed available for cruise set, and
perform cruise set operation again.
34 Prohibited when accelera-
tor pedal position large is
continued.
The vehicle has been driven at higher speed
than set vehicle speed for an abnormally
long time (approximately 10 minutes) during
cruise driving.
This DTC is displayed when driving for a
long period of time at higher speed than
appropriate cruise set vehicle speed by
operating accelerator pedal. In this case,
release the cruise set.
35 Prohibited when vehicle
speed feedback unavail-
able.
Set vehicle speed cannot be kept because
of some reasons (steep uphill, parking
brake, abnormal decrease of engine output,
etc.) during cruise driving.
This DTC is displayed when driving condi-
tion is not suitable for cruise control. Perform
cruise set operation again after clearing the
possible cause.
41 VDC/TCS operation Vehicle dynamics control (VDC) or TCS is
operated during cruise driving or cruise set-
ting.
This DTC is displayed when driving condi-
tion is not suitable for cruise control. Perform
cruise set operation again after clearing the
possible cause.
43 ABS/VDC malfunction Vehicle dynamics control (VDC) system mal-
function is detected during cruise driving or
cruise setting.
44 Body integrated unit mal-
function
Body integrated unit system malfunction is
detected during cruise driving or cruise set-
ting.
45 Meter Failure Combination meter malfunction is detected
during cruise driving or cruise setting.

1CHECK NEUTRAL POSITION SWITCH.
1) Connect the Subaru Select Monitor to data
link connector.
2) Turn the ignition switch and Subaru Select
Monitor switch to ON.
3) Select {Engine} from the main menu.
4) Then, select {Current Data Display &
Save}.

when select lever is shifted into
“P” or “N” range? Is Subaru
Select Monitor OFF when
select lever is shifted to a
range other than the “P” or “N”
range?
Replace the ECM.

Is voltage more than 10 V
when select lever is shifted to a
range other than “P” or “N”
range? Is voltage less than 1 V
when select lever is shifted into
“P” or “N” range?

ness for open or
short circuit
between ignition
switch and ECM.
Step Check Yes No
1CHECK ABS WARNING LIGHT.
1) Turn the ignition switch to ON.

meter is completed, check if the VDC warning
light continues to illuminate.
Does the VDC warning light
continue to illuminate?
Check the
VDCCM.

A: WIRING DIAGRAM
B: INSPECTION
1. CHECK THE OPERATION OF THE NAVI-
GATION.
Start the engine, and then inspect that the opening
screen is displayed.
Standard value: The opening screen should be dis-
played.
OK: Normal
NG: When not displayed, check the signal line con-
nector and the audio connector. If there are no
problems in the connecting lines or the lines were
repaired, check that the opening screen is dis-
played.
At this point, if the display is not viewable, the unit is
defective.
2. CHECK THE DVD-ROM.
An opening screen is displayed, then it switches to
the map screen after a while.
When a screen other than the opening screen is
displayed, press the «MAP» key.
Standard value: The map screen should be dis-
played.
OK: Normal
NG: If the map screen is not displayed, check
whether the DVD-ROM is set in the navigation sys-
tem, whether the correct side is set, type of the
DVD-ROM, the existence of any scratches, etc. If
there are no problems on the DVD-ROM, the main
body is defective.
3. CHECK EACH CONNECTION
If there are no problems in the inspections of 1 and
2 above, use “
vice to perform inspection.
4. SWITCHING TO CONNECTION INSPEC-
TION MODE
1) Press the menu key.
2) Select navigation setup from the menu screen.
3) Select navigation information from the naviga-
tion setup screen.
4) Select the vehicle signal from the navigation in-
formation screen.
5) The display will switch to the vehicle signal (for
connection inspection) screen.
6) Check that the display changes according to
each operation
ON: Normal
NG: Check the circuit when the display does not
change.
5. CHECK THE GPS ANTENNA
NOTE:
When checking the GPS antenna, perform the
check operation outdoors to improve the receiver
sensitivity.
Make sure that a value other than “zero” is dis-
played in the GPS item.
OK: Normal
NG: If “No positioning” is displayed, check the GPS
antenna connection.
If the GPS display is red, the main unit could be
faulty.
6. CHECK THE BACK SENSOR
NOTE:
Before starting inspections, inspect the safety
around the rear end of the vehicle.
1) Turn the ignition switch to ON.
2) Pull the parking brake and depress the brake,
then put the gear in reverse.
3) Make sure that “On” is lit in the back sensor item.
Standard Value: “On” should be lit.
On: Normal
NG: If “On” does not light, check the signal line con-
nection. If there are no problems, the unit could be
faulty.
7. CHECK THE ILLUMINATION
1) Turn the lighting switch to level 1.
NOTE:
Make sure that the bright switch is not turned ON at
this time.
2) Make sure that “On” lights in the illumination
item, then the screen fades out.
Standard Value: “On” should be lit.
OK: Normal
NG: If “On” does not light, check the signal line con-
nection. If there are no problems, the unit could be
faulty.
8. CHECK THE PARKING SIGNAL
NOTE:
The side brake signal is normally “OFF”, so operat-
ing it will produce no change.
