Telematics System -- How To Proceed With Troubleshooting |
- HINT:
- Use the following procedure to troubleshoot the telematics system.
- *: Use the GTS.
1.VEHICLE BROUGHT TO WORKSHOP |
The telematics system provides a variety of functions. Therefore, it is important to identify whether a malfunction is related to the communication system, including radio wave signal conditions, or any other systems. Carefully confirm the conditions that caused the malfunction in order to determine if a temporary problem with the radio wave signal condition caused the malfunction.
Displayed Message and Problem Symptom
| Cause
|
A message is displayed temporarily indicating to try again after moving the vehicle because the center cannot be accessed and the screen cannot be displayed, due to a busy line, etc.
| This is caused when there is a problem with the radio wave signal conditions or when the base station is busy. This is not a malfunction (inform the customer that this is not a malfunction and ask them to use the system as is).
|
A message is displayed temporarily indicating to try again after waiting for a while because the lines are busy
| This is caused when there is a problem with the radio wave signal conditions or when the base station is busy. This is not a malfunction (inform the customer that this is not a malfunction and ask them to use the system as is).

3.INSPECT BATTERY VOLTAGE |
Measure the battery voltage.
- Standard voltage:
- 11 to 14 V
- HINT:
- If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.
4.CHECK CAN COMMUNICATION SYSTEM* |
Use the GTS to check if the CAN communication system is functioning normally (Click here).

6.PERFORM TROUBLESHOOTING BASED ON MALFUNCTION SYMPTOM |
Refer to Terminals of ECU (Click here).
Adjust, repair or replace as necessary.
- NOTICE:
- Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Telematics System (Click here).
