AV:DTC 96 CURTAIN AIRBAG MODULE LH FAILURE
DTC DETECTING CONDITION:
•Curtain airbag harness (LH) is shorted to power supply.
•Airbag control module is faulty.
CAUTION:
•Before diagnosing the airbag system, be sure to turn the ignition switch to OFF, disconnect the
ground terminal from battery, and wait more than 20 seconds before starting to work.
•After replacing the airbag module, seat belt pretensioner, roll connector, control module and sen-
sor, reconnect each part and confirm that the warning light operates properly.
•When inspecting the airbag main harness, disconnect the airbag module connectors of driver's
and passenger's seats for safety reasons.
•When inspecting the airbag rear harness, disconnect the side airbag module connector, curtain
airbag module connector and seat belt pretensioner connector for safety reasons.

AIRBAG SYSTEM (DIAGNOSTICS)
Step Check Yes No
1CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the airbag control module, curtain air-
bag module LH and the curtain airbag sensor
LH.
Is there poor contact? Replace the airbag
rear harness LH
with the body har-
ness.
Go to step 2.
2CHECK SIDE AIRBAG MODULE.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the connector (AB31) from
(AB39), and connect the connector (1F) in test
harness F to connector (AB31).
3) Connect the airbag resistor to the connec-
tor (3F) of test harness F.
4) Connect the battery ground terminal and
turn the ignition switch to ON.
Does the airbag warning light
illuminate for 6 seconds and go
off?
Replace the cur-
tain airbag mod-
ule (LH). <Ref. to
AB-19, Curtain Air-
bag Module.>
Go to step 3.
3CHECK AIRBAG REAR HARNESS LH (CUR-
TAIN AIRBAG MODULE HARNESS LH).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the connector (AB21) from seat
belt pretensioner (LH).
3) Disconnect the connector (AB19) from side
airbag module (LH).
4) Disconnect the airbag resistor from test
harness F.
5) Disconnect the connector (AB17) from air-
bag control module.
6) Connect the connector (1U) in the test har-
ness U to connector (AB17).
7) Connect the battery ground terminal and
turn the ignition switch to ON.
8) Measure the voltage between connector
(5U) in the test harness U and chassis ground.
Connector & terminal
(5U) No. 1 (+) — Chassis ground (–):
(5U) No. 3 (+) — Chassis ground (–):
Is the voltage less than 1 V? Go to step 4.Replace the airbag
rear harness LH
with the body har-
ness.
4CHECK AIRBAG CONTROL MODULE.
1) Connect all the connectors.
2) Erase the memory.
3) Perform the inspection mode.
4) Read the DTC.
Is the same DTC displayed? Replace the airbag
control module.
<Ref. to AB-21,
Airbag Control
Module.>
Go to step 5.
5CHECK ANY OTHER DTC ON DISPLAY.Is any other DTC displayed? Check DTC using
“List of Diagnostic
Tr o u b l e C o d e
(DTC)”. <Ref. to
AB(diag)-45, List
of Diagnostic Trou-
ble Code (DTC).>

Subaru Select Monitor
CRUISE CONTROL SYSTEM (DIAGNOSTICS)
5. Subaru Select Monitor
A: OPERATION
1. GENERAL DESCRIPTION
The on-board diagnosis function of the cruise con-
trol system uses Subaru Select Monitor.
The on-board diagnosis function operates in two
categories, which are used depending on the type
of problems;
1) Cruise Control Cancel Conditions Diagnosis:
(1) This category of diagnosis requires actual
vehicle driving in order to determine the cause,
as when cruise speed is cancelled during driv-
ing although cruise cancel condition is not en-
tered.
(2) Cruise control memory in ECM stores the
cancel condition (Code No.) which occurred
during driving. When there are multiple cancel
conditions (Code No.), they are shown on the
Subaru Select Monitor.
CAUTION:
•The cruise control memory stores not only
the cruise “cancel” which occurred (although
“cancel” operation is not entered by the driver),
but also the “cancel” condition input by the
driver.
•The content of memory is cleared when igni-
tion switch or cruise control main switch is
turned OFF.
2) Real-time Diagnosis:
Real-time diagnosis function is used to determine
whether or not the input signal system is in good or-
der, according to signal emitted from switches, sen-
sors, etc.
(1) Vehicle cannot be driven at cruise speed
when the problem occurs in the cruise control
system or relevant circuits.
(2) Monitor the signal conditions from switches
and sensors.
2. CRUISE CONTROL CANCEL CONDI-
TIONS DIAGNOSIS
1) Prepare the Subaru Select Monitor kit.
2) Connect the diagnosis cable to Subaru Select
Monitor.
3) Insert the cartridge to Subaru Select Monitor.
<Ref. to CC(ETC)(diag)-4, SPECIAL TOOL,
PREPARATION TOOL, General Description.>
4) Connect the Subaru Select Monitor to data link
connector.
(1) Data link connector is located in the lower
portion of the instrument panel (on the driver’s
side).
(2) Connect the diagnosis cable to data link
connector.
5) Start the engine and turn the cruise control main
switch to ON.

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 “<Ref. to WI-112, WIRING DIA-
GRAM, Navigation System.>” of the navigation de-
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.

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.
