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. AND 32 VEHICLE SPEED SENSOR, Diag-
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.

2CHECK LAN COMMUNICATION CIRCUIT
ERROR DISPLAY
Check if the communication error is displayed
on the odo/trip meter in combination meter.
Is the error code «Er xx» dis-
played on odo/trip meter?

9. CHECK SPEED SENSOR
NOTE:
•Before starting inspections, inspect the safety
around the vehicle.
•Lift-up the vehicle as necessary.
•When the diagnostic trouble code is input in the
VDC CM, clear the memory.
1) Move the vehicle 2 to 3 meters (6.6 to 9.8 ft).
2) Check that the numbers from the speed sensor
are displayed.
Standard value: Vehicle speed is to be shown in
numbers.
OK: Normal
NG: If vehicle speed is not displayed, check the sig-
nal line connection. If there are no problems, the
unit could be faulty.

Basic Diagnostic Procedure
LAN SYSTEM (DIAGNOSTICS)
1. Basic Diagnostic Procedure
A: PROCEDURE
1. WITH SUBARU SELECT MONITOR
CAUTION:
•Subaru Select Monitor is required for reading DTC, performing diagnosis and reading current data.
•Remove foreign matter (dust, water, oil, etc.) from the body integrated unit connector during re-
moval and installation.
•For model with immobilizer, registration of immobilizer may be needed after the replacement of
controller etc. For detailed procedure, refer to the REGISTRATION MANUAL FOR IMMOBILIZER.
NOTE:
•To check harness for broken wires or short circuits, shake trouble spot or connector.
•Check List for Interview.
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Ask the customer when and how the trou-
ble occurred using interview check list. LAN(diag)-3, Check List for Interview.>
2) Check the display of communication error
display. (Combination meter, odo/trip meter)
Is the communication error dis-
played?
Go to step 3.Go to step 2.
2BASIC INSPECTION
Check the components which might affect
body control. TION, General Description.>
Is the component that might
influence the body control
problem normal?
Go to step 3.Repair or replace
each component.
3CHECK INDICATION OF DTC.
1) Read DTC of all systems. LAN(diag)-12, READ DIAGNOSTIC TROUBLE
CODE (DTC), OPERATION, Subaru Select
Monitor.>
NOTE:•The LAN system is for the overall vehicle, so
read the DTC of all systems.
•If the communication function of the Subaru
Select Monitor cannot be executed normally,
check the communication circuit. LAN(diag)-32, COMMUNICATION FOR INI-
TIALIZING IMPOSSIBLE, Diagnostic Proce-
dure with Diagnostic Trouble Code (DTC).>
2) Record all DTC.
Is a DTC other than CAN com-
munication displayed in the
output code?
