[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. 
|
[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. 
|
| 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 |
