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

Display the data monitor [Diagnostic Alert Active] of the Telematics. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>Data Monitor .

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 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 the DTC of telematics. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>Diagnostic Trouble Code (DTC) .

Is DTC displayed?

• Yes: Perform the diagnosis for the displayed DTCs. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>Diagnostic Trouble Code (DTC)>LIST .
• No: Go to 4. 

Ask the user where he/she turned the ignition switch to OFF after the warning light was lit.

Is the location, where the ignition switch was turned to OFF after the warning light was lit, within the AT&T cellular coverage area? (For the AT&T 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.
