The System Does Not Notify The Center Even If The I-Button Is Pressed Upon Vehicle Malfunction

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.)".
WARNING: CommCheck is required after replacing the DCM. Ref. to ENTERTAINMENT>Telematics System>OPERATION>REGISTRATION (COMM CHECK) .
  1. CHECK THE SUBSCRIPTION STATUS. 

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

    Is the data TRUE?

    • Yes: Go to 2. 
    • No: The user does not have a service subscription; therefore, it is not a failure.
  2. CHECK DTCS. 

    Read DTCs of the Telematics. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>Diagnostic Trouble Code (DTC) .

    Is DTC displayed?

  3. CHECK RECEIVED SIGNAL STRENGTH WHEN I-BUTTON WAS PRESSED (CHECK DATA MONITOR). 

    Display the data monitor [RSSI at SOS/ICALL(1)] of the Telematics. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>Data Monitor .

    Is the data 26% or more?

    • Yes: Go to  5.
    • No: Go to 4. 
  4. CHECK THE AT&T CELLULAR COVERAGE AREA. 
    1. Check whether the i-button was pressed within the cellular coverage area.
    2. Display the data monitor [GPS Data at Time of Button Push(1)] of the Telematics. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>Data Monitor .

    Is the displayed location data indicated 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: Go to 5. 
    • No: The i-button was pressed outside the cellular coverage area.
  5. CHECK COMMUNICATION STATUS OF WHEN I-BUTTON WAS PRESSED (CHECK DATA MONITOR). 

    Display the data monitor [Call status at SOS/ICALL Event(1)] of the Telematics. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>Data Monitor .

    If the data shows [Call Started] or [Call Connected]; go to  1.

    If the data shows Call Not Started; go to  2.

    If the data shows [No Network Service]; go to  3.

    If the data shows Call Ended by SXM; go to  4.

    • A: Go to 6. 
    • B: Go to  7.
    • C: Replace the antenna. Ref. to ENTERTAINMENT>Antenna .
    • D: The connection ended due to a server-side reason; therefore, there is no failure on the vehicle.
  6. CHECK COMMUNICATION STATUS OF WHEN I-BUTTON WAS PRESSED (CHECK DATA MONITOR). 

    Display the data monitor [Timestamp at Time of Button Push(1)] of the Telematics. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>Data Monitor .

    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 i-button operation match with the data?

  7. CHECK I-BUTTON. 

    Check the i-button. Ref. to TELEMATICS SYSTEM (DIAGNOSTICS)>Diagnostic Procedure with Diagnostic Trouble Code (DTC)>DTC B2A09 I-CALL BUTTON CIRCUIT .

    Is the check result OK?
