[SOC Inspection]
1. | Connect the GDS to the Data Link Connector (DLC). |
2. | Turn the ignition switch ON. |
3. | Check the SOC in GDS service data. ![](images/inspection-464/413/slhhc5052l.gif)
|
[Battery Voltage Inspection]
1. | Connect the GDS to the Data Link Connector (DLC). |
2. | Turn the ignition switch ON. |
3. | Check the cell and pack voltage in GDS service data. Cell Voltage : 2.5 - 4.3V Pack Voltage : 180 - 300V |

|
[Voltage Sensing Circuit Inspection]
1. | Shut off the high voltage circuit. (Refer to "High Voltage Shutoff Precedure") |
2. | Remove the battery temperature sensor. (Refer to "Battery Temperature Sensor") |
3. | Check the continuity of the wiring between the harness connectors of the module and BMS ECU. ![](images/inspection-464/413/syehc1604n_n.gif)
|
4. | Connect the harness connectors to the BMS ECU. |
5. | For checking the short circuit to ground, measure resistance between the module harness connectors and chassis ground. Specification : 1 MΩ or higher |

|
[Isolation Resistance Inspection]
1. | Connect the GDS to the Data Link Connector (DLC). |
2. | Turn the ignition switch ON. |
3. | Check the isolation resistance in GDS service data. Isolation Resistance : Around 1.0 MΩ |
