The System Does Not Notify The Telematics Service Provider Center Automatically After Collision

Probable cause:

Airbag Control Module malfunction, no contract agreement, out of service area, DCM malfunction, antenna malfunction, server side malfunction

CAUTION:

After the DCM is replaced, registrations of CommCheck and immobilizer system are required. Ref. to ENTERTAINMENT & MONITORING>TELEMATICS SYSTEM>OPERATION>REGISTRATION (COMM CHECK) .
Before performing diagnosis, refer to "CAUTION" in "General Description". Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>GENERAL DESCRIPTION>CAUTION .

NOTE: Perform the diagnostics for "Phone conversation is not possible. (The microphone does not respond to a voice. No sound is heard from the speaker.)". Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTICS WITH PHENOMENON>INSPECTION>PHONE CONVERSATION IS NOT POSSIBLE. (THE MICROPHONE DOES NOT RESPOND TO A VOICE. NO SOUND IS HEARD FROM THE SPEAKER.) .

CHECK COLLISION TYPE .
Check the type of collision of the vehicle.

Is it a frontal collision, or a side collision, or a rollover?

Yes: Go to 2.

No: For rear collision, Go to 4.
CHECK AIRBAG WARNING LIGHT .
Check the airbag warning light.

Does the airbag warning light illuminate at all times?

Yes: Go to 3.

No: There is no malfunction in the airbag system. Since the airbag Control Module does not transmit the collision detection signal in the event of a minor collision, it is normal that the automatic notification function does not work.
CHECK DTCS .
Read the DTC of [Airbag] using the Subaru Select Monitor. Ref. to AIRBAG (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .

Is any of the DTC [Front Impact Deployment], [Side Impact Deployment], or [Rollover Deployment History] displayed?

Yes: There is no malfunction in the airbag system. Go to 7.

No: Perform the diagnosis for the airbag system. Ref. to AIRBAG (DIAGNOSTICS)>BASIC DIAGNOSTIC PROCEDURE .
CHECK COLLISION DETECTION SIGNAL RECEPTION STATUS .
Using the Subaru Select Monitor, check the following items in the [Data monitor] of [Telematics]. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DATA MONITOR .
- TimeStamp at ACN Event: Date
- TimeStamp at ACN Event: UTC *UTC is the basis for local times worldwide.
Is a time stamp recorded?

Yes: Go to 7. (Rear collision detection was activated)

No: Go to 5.
CHECK DTCS .
Read the DTC of [Telematics] using the Subaru Select Monitor. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .

Are any DTCs displayed?

Yes: Perform the diagnosis for the displayed DTCs. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST .

No: Go to 6.
CHECK AIRBAG WARNING LIGHT .
Check the airbag warning light.

Does the airbag warning light illuminate at all times?

Yes: Perform the diagnosis for the airbag system. Ref. to AIRBAG (DIAGNOSTICS)>BASIC DIAGNOSTIC PROCEDURE .

No: There is no malfunction in the airbag system. Since the airbag Control Module does not transmit the collision detection signal in the event of a minor collision, it is normal that the automatic notification function does not work.
CHECK THE SUBSCRIPTION STATUS .
Using the Subaru Select Monitor, check the following items in the [Data monitor] of [Telematics]. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DATA MONITOR .
- ACN Active
Is the data [TRUE]?

Yes: Go to 8.

No :
- The user does not have a service subscription; therefore, it is not a failure.
- When the user's service subscription is not set to [TRUE], set the provisioning.
When the setting does not change to [TRUE] even after setting the provisioning again, replace the DCM. Ref. to ENTERTAINMENT & MONITORING>DATA COMMUNICATION MODULE .
CHECK DTCS .
Read the DTC of [Telematics] using the Subaru Select Monitor. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .

Are any DTCs displayed?

Yes: Perform the diagnosis for the displayed DTCs. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST .

No: Go to 9.
CHECK THE RECEIVED SIGNAL STRENGTH AT THE TIME OF THE ACCIDENT (CHECK THE DATA MONITOR) .
Using the Subaru Select Monitor, check the following items in the [Data monitor] of [Telematics]. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DATA MONITOR .
- RSSI at ACN Event
Is the data 26 [%] or more?

Yes: Go to 11.

No: Go to 10.
CHECK THE AT & T CELLULAR COVERAGE AREA .
Check whether the collision occurred within the cellular coverage area.

Is the location where the collision occurred within the cellular coverage area? (For the cellular coverage area, refer to the AT & T website. The system operates only on 3G and 4G technology.)

Yes: Go to 11.

No: The collision occurred outside the cellular coverage area.
CHECK THE COMMUNICATION STATUS AT THE TIME OF THE ACCIDENT (CHECK THE DATA MONITOR) .
Using the Subaru Select Monitor, check the following items in the [Data monitor] of [Telematics]. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DATA MONITOR .
- Call Status at ACN Event
If the data shows [Call Started] or [Call Connected]; Go to A.

If the data shows [Call Not Started]; Go to B.

If the data shows [No Network Service]; Go to C.

If the data shows [Call Ended by SXM]; Go to D.
1. Go to 12.
2. Replace the DCM. Ref. to ENTERTAINMENT & MONITORING>DATA COMMUNICATION MODULE .
3. Replace the antenna. Ref. to ENTERTAINMENT & MONITORING>ANTENNA .
4. The connection ended due to a server-side reason; therefore, there is no failure on the vehicle.
CHECK THE TIME OF THE ACCIDENT (CHECK THE DATA MONITOR) .
Using the Subaru Select Monitor, check the following items in the [Data monitor] of [Telematics]. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DATA MONITOR .
- TimeStamp at ACN Event: Date
- TimeStamp at ACN Event: UTC *UTC is the basis for local times worldwide.
NOTE: The time stamp is displayed in the Coordinated Universal Time (UTC), which is different from actual time at each location. Therefore, time difference needs to be corrected for use.
Example: [12/22 01:30 in UTC time] is corrected as [12/21 20:30 in New York time].

Does the time of the accident match with the data?

Yes: Replace the antenna. Ref. to ENTERTAINMENT & MONITORING>ANTENNA .

No: Replace the DCM. Ref. to ENTERTAINMENT & MONITORING>DATA COMMUNICATION MODULE .
