must be followed.
Before working on any high voltage system, be sure to wear the following Personal Protection Equipment:
* Safety glasses with appropriate side shields when within 50 feet of the vehicle, either indoors or outdoors.
* Certified and up-to-date Class "0" Insulation gloves rated at 1000V with leather protectors.
- 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 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.
锟斤拷If 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.
锟斤拷If not within the specified range, replace the drive motor battery assembly.
7. If all circuits test normal, replace the drive motor generator battery control module.
