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}.
5) Check the neutral position switch signal by
shifting the select lever to “P” or “N” range.
Is Subaru Select Monitor ON
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.

Engine Control
Module (ECM).>
Go to step 2.
2CHECK TCM OUTPUT VOLTAGE.
1) Turn the ignition switch to ON.
2) Measure the voltage between TCM har-
ness connector terminal and chassis ground.
Connector & terminal
(B55) No. 19 (+) — Chassis ground (–):
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?
Go to step 3.Check the TCM.
2, Basic Diagnos-
tic Procedure.>
3CHECK HARNESS BETWEEN TCM AND
ECM.
1) Turn the ignition switch to OFF.
2) Disconnect the harness connector from
TCM and ECM.
3) Measure the resistance between TCM har-
ness connector terminal and ECM harness
connector terminal.
Connector & terminal
(B136) No. 31 — (B55) No. 19:
Is the resistance less than 10
Ω?
Replace the ECM.

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 “ 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.
