CHECK BODY INTEGRATED UNIT.
1) Start the engine, and set the vehicle speed
at 20 km/h (12 MPH) or more.
2) Read the “Front Wheel Speed” of the body
integrated unit using Subaru Select Monitor.
<Ref. to LAN(diag)-12, OPERATION, Subaru
Select Monitor.>

Is the data displayed as
999.9 km/h?

Check the follow-
ing items.
• LAN system
<Ref. to
LAN(diag)-65,
DTC U1223 CAN-
HS VDC/ABS NO-
RECEIVE DATA,
Diagnostic Proce-
dure with Diagnos-
tic Trouble Code
(DTC).>
• VDC
<Ref. to
VDC(diag)-2,
Basic Diagnostic
Procedure.>
• ABS
<Ref. to
ABS(diag)-2, Basic
Diagnostic Proce-
dure.>

Go to step 3.

CHECK BODY INTEGRATED UNIT.
Read the “Front Wheel Speed” of the body inte-
grated unit using Subaru Select Monitor. <Ref.
to LAN(diag)-12, OPERATION, Subaru Select
Monitor.>

Is the vehicle speed displayed
correctly?

Replace the body
integrated unit.
<Ref. to SL-56,
REMOVAL, Body
Integrated Unit.>

Go to step 4.

CHECK AMBIENT SENSOR.
Blow hot air at the ambient sensor, and read the
voltage of ambient sensor using Subaru Select
Monitor. <Ref. to LAN(diag)-12, OPERATION,
Subaru Select Monitor.>

Does the voltage change?

Go to step 8.

Go to step 5.

5

CHECK HARNESS.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from the body
integrated unit and the ambient sensor.
3) Measure the resistance of harness between
body integrated unit connector and ambient
sensor connector.

Connector & terminal

(B281) No. 10 — (F78) No. 1:
(B281) No. 3 — (F78) No. 2:

Is the resistance less than 1

:? Go to step 6.

Repair the open
circuit of harness.

6

CHECK HARNESS.
Measure the resistance between body inte-
grated unit connector and chassis ground.

Connector & terminal

(B281) No. 10 — Chassis ground:
(B281) No. 3 — Chassis ground:

Is the resistance less than 1 M

:? Go to step 7.

Repair the short
circuit of harness.

7

CHECK AMBIENT SENSOR.
Blow hot air at the ambient sensor, and read the
resistance between ambient sensor terminals.

Terminals

No. 1 — No. 2:

Does the resistance change?

Replace the body
integrated unit.
<Ref. to SL-56,
REMOVAL, Body
Integrated Unit.>

Replace the ambi-
ent sensor.

8

CHECK AMBIENT SENSOR.
Blow cold air at the ambient sensor, and read
the ambient temperature using Subaru Select
Monitor. <Ref. to LAN(diag)-12, OPERATION,
Subaru Select Monitor.>

Does the temperature change
(at lower temperatures)?

Replace the clock
body. <Ref. to IDI-
28, Clock.>

Replace the body
integrated unit.
