- Visually and functionally inspect the gloves before use.

- Wear the Insulation gloves at all times when working with the high voltage battery assembly, whether the system is energized or

not.

Failure to follow the procedures exactly as written may result in serious injury or death.

1. Ignition OFF, disable the high voltage at the drive motor generator battery. Refer to High Voltage Disabling ().

2. Disconnect the X4 harness connector at the drive motor battery control module.

3. Connect to the EL-48571 high voltage battery pin out box.

4. Install the high voltage manual disconnect lever. Measure and record each of the 20 battery voltages.

5. Each battery voltage reading should be between 10-19 V.

瀚慖f not within the specified range, replace the drive motor battery assembly.

6. Each battery voltage reading should be within 1.5 V of each other.

瀚慖f not within the specified range, replace the drive motor battery assembly.

7. If all circuits test normal, replace the drive motor battery control module.
