Circuit/System Testing
WARNING: This page is about a different variant/trim than selected.
- Identify how to disable high voltage.
- Identify how to test for the presence of high voltage.
- Identify condition under which high voltage is always present and personal protection equipment (PPE) and proper procedures must be followed.
- Safety glasses with appropriate side shields when within 15 meters (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 with leather protectors at all times when working with the high voltage battery assembly, whether the system is energized or not.
- Ignition OFF, disable the high voltage at the drive motor generator battery. Refer to High Voltage Disabling .
- Disconnect the X4 harness connector at the drive motor battery control module.
- Connect the EL-48571 high voltage battery pin out box.
- Install the high voltage manual disconnect lever. Measure and record each of the 20 battery voltages.
- Each battery voltage reading should be between 10-19 V.
- If not within the specified range, replace the drive motor battery assembly.
- Each battery voltage reading should be within 1.5 V of each other.
- If not within the specified range, replace the drive motor battery assembly.
- If all circuits test normal, replace the drive motor generator battery control module.
WARNING:
Always perform the High Voltage Disabling procedure prior to servicing any High Voltage component or connection. Personal Protection Equipment (PPE) and proper procedures must be followed.
The High Voltage Disabling procedure includes the following steps:
Before working on any high voltage system, be sure to wear the following Personal Protection Equipment:
Failure to follow the procedures may result in serious injury or death.
