1. 1
   Self-Diagnosis: Checks malfunction and Diagnostic Trouble Code (DTC)
2. 2
   Current Data: Check the system input/output status.
3. 3
   Select "Vehicle Model" and "eCall System" to inspect the vehicle with the tester in sequence.
4. 4
   To determine the cause of a fault in each module using self-diagnosis, select "Diagnostic Trouble Code".

   

   

5. 5
   Select the "Current Data" menu to check the current input/output data.

   

   

6. 6
   Turn the ignition off.
7. 7

    Conditions Preventing Test Mode Operation

    1. PSAP Call in Progress
    2. Callback Mode: The eCall system enters callback mode after a successful call and remains on standby for 120 minutes to receive calls from the call center.
    3. Test mode is automatically terminated when the vehicle speed reaches 1 km/h or more, or after traveling 300 m or more.
    4. Less than two minutes have passed since the previous test call was completed.
13. 13
    Test Mode Sequence (Audio Guidance)

    1. LED Test
    2. Speaker Test
    3. MIC Test
    4. BUB (Back-Up Battery built into eCall unit) Test (No separate notification is given if the BUB is in normal condition.)

       Back-Up Battery Voice Prompt: When the "eCall Back-Up Battery Voltage Low" message is played, repeat the test mode after the battery has been sufficiently charged during driving.

    5. Test Call (Pressing the SOS button sends the test result to the PSAP.)

eCall Parameter Download: The eCall parameter download is used to change the eCall parameter value for Europe. eCall Test Mode: Press the SOS TEST button to activate the voice guidance and test the eCall system by following the instructions. In the Test Call stage, which is the final stage of the test mode, press the SOS button following the voice guidance to send data on faulty components to the call center. To exit the test mode, press the SOS TEST button at the voice guidance prompt.

The red LED remains on if one or more DTCs for the eCall system are set. If the red LED is on, be sure to use the diagnostic tool (GDS) to check for failure.

Backup Battery Inspection: The backup battery (BUB) built into the eCall system has a limited service life, and prolonged use may reduce its charge/discharge performance. The backup battery ensures operation of the eCall system when the vehicle battery cannot be used due to a collision. Be sure to inspect the backup battery if the red LED illuminates, and replace it if necessary.

Back-up battery warranty: 3 years. Inspect the back-up battery every three years and replace it if necessary. (Refer to Emergency Call Module – Repair Procedures.)

The eCall system is designed to place an emergency call to the call center in an emergency. Arbitrary removal or operation of system components may affect occupant safety and may result in a false accident report to the emergency call center.
