INFOTAINMENT(DIAGNOSTICS) > Inspection Mode
PROCEDURE

DTC can be diagnosed by executing the Inspection Mode. After correcting the DTC, perform a necessary inspection mode and make sure that the function is resumed correctly and the DTC is recorded.

1.

Using the Subaru Select Monitor, perform the clear memory of [Infotainment]. COMMON(diag)>Clear memory

2.

Using the Subaru Select Monitor, read the DTC of [Infotainment] to check that there is no DTC displayed. INFOTAINMENT(DIAGNOSTICS) >Diagnostic Trouble Code (DTC)

If the DTC is displayed on the screen, the trouble is still present. Perform the diagnosis for the displayed DTCs. After solving the DTC, repeat from step 1).

3.

Turn the ignition switch to ON, and wait for 1 minute or more.

4.

Using the Subaru Select Monitor, read the DTC of [Infotainment] to check that there is no DTC displayed. INFOTAINMENT(DIAGNOSTICS) >Diagnostic Trouble Code (DTC)

If the DTC is displayed on the screen, the trouble is still present. Perform the diagnosis for the displayed DTCs.

INFOTAINMENT(DIAGNOSTICS) > Diagnostic Procedure for Subaru Select Monitor Communication
INSPECTION

Detecting condition:

- Defective harness connector

- Power supply circuit malfunction

- Infotainment system module malfunction

- Defective CAN communication circuit

- Defective Subaru Select Monitor

Trouble symptom:

Communication is impossible between the infotainment system module and Subaru Select Monitor.

Wiring diagram:

Audio and navigation system WIRING SYSTEM>Audio and Navigation System>WIRING DIAGRAM

Before performing diagnosis, refer to “CAUTION” in “General Description”. INFOTAINMENT(DIAGNOSTICS) >General Description>CAUTION

1. CHECK OTHER COMMUNICATION.

Communicate with the system other than the infotainment using the Subaru Select Monitor.

Is the communication to other control module possible?

2

Perform the “Communication for Initializing Impossible” of LAN system.

2. CHECK LAN SYSTEM.

Inspect LAN system. LAN SYSTEM (DIAGNOSTICS)>Basic Diagnostic Procedure>PROCEDURE

Is the check result OK?

3

Perform the inspection according to the diagnosis for LAN system.

3. CHECK FUSE.

Check the fuse of the infotainment. ENTERTAINMENT & MONITORING>Relay and Fuse>LOCATION

Is the check result OK?

4

Replace the fuse. If the replaced fuse blows out easily, repair the ground short circuit of the harness between the battery and audio connector, or between the navigation unit connectors.

4. CHECK HARNESS (POWER SUPPLY CIRCUIT).
1.

Turn off the audio or navigation unit.

2.

Turn the ignition switch to OFF.

3.

Disconnect the audio connector or navigation unit connector.

4.

Turn the ignition switch to ON.

5.

Using the tester, measure the voltage between audio connector or navigation unit connector and chassis ground.

Connector & terminal

(i85) No. 3 (+) — Chassis ground (−):

(i85) No. 4 (+) — Chassis ground (−):

Is the voltage 10 — 13 V?

5

Repair the open circuit of harness between audio connector or navigation unit connector and fuse.

5. CHECK HARNESS (GROUND CIRCUIT).
1.

Turn the ignition switch to OFF.

2.

Using the tester, measure the resistance between audio connector or navigation unit connector and chassis ground.

Connector & terminal

(i85) No. 7 — Chassis ground:

Is the resistance less than 1 Ω?

6

Repair the open circuit of harness between audio connector or navigation unit connector and fuse.

6. CHECK INFOTAINMENT SYSTEM MODULE.
1.

Turn the ignition switch to OFF.

2.

Connect the audio connector or navigation unit connector.

3.

Perform the communication with the infotainment system.

Is communication possible?

It is possible that temporary poor communication occurs.

Replace the audio or navigation unit. ENTERTAINMENT & MONITORING>Audio ENTERTAINMENT & MONITORING>Navigation Body

Navigation system check

GPS related check: Status of the GPS signal reception can be checked. When there is faulty in reception status, position detection or date indication, re-check the reception status at a location with a fine view and no obstacles around that will interrupt the signal reception. When normal condition is still not obtained, the GPS antenna may be faulty.

- GPS/Reception number: Normal when it is indicated in blue.

- GPS/Status: Normal when OK is indicated.
