When A Malfunction Indicator Light/Warning Light Is Lit, Notification Is Not Sent

Probable cause:

No contract agreement, out of service area, server side malfunction, DCM malfunction

CAUTION: Before performing diagnosis, refer to "CAUTION" in "General Description". Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>GENERAL DESCRIPTION>CAUTION .

CHECK THE SUBSCRIPTION STATUS .
1. Turn the ignition switch to ON.
2. Using the Subaru Select Monitor, check the following items in the [Data Monitor] of [Telematics]. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>DATA MONITOR .
- Diagnostic Alert Active
Does the data display [TRUE]?

Yes: Go to 2.

No: The user does not have a service subscription; therefore, it is not a failure.
CHECK WARNING LIGHT .
Check if the warning light illuminates.

Does it Illuminate?

Yes: Go to 3.

No: Currently no failure is found. Since the warning light is not lit, notification is not sent.
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 4.
CHECK THE AT & T CELLULAR COVERAGE AREA .
After the warning light was lit, check whether the location where the ignition switch was turned to OFF is within the cellular coverage area.

Is the location where the ignition switch was turned to OFF after the warning light was lit 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: Check the Starlink Server report to verify that there was no server outage that coincides with the day/time the customer reported that the issue occurred. (Refer to STARLINK Server Maintenance/Down Report under Reports and Starlink section in Subarunet.) If no outage exists for that time frame, it is possible that there was environmental interference (radio waves, etc.) when the user performed the operation. No further actions are recommended.

No: The location where the ignition switch was turned to OFF (where warning light illumination information was sent) was outside the cellular coverage area.
