Warning
This procedure verifies that high voltage power is no longer available to high voltage components (A/C compressor, inverters, etc). Perform this procedure before servicing high voltage components.
Warning
执行暴露在高压之下的任何程序之前，请取下佩戴的所有首饰（手表、手链、戒指、项链、耳环、身份牌、穿刺饰品等），并取出口袋中的所有物品（钥匙、硬币、钢笔、铅笔、工具、钮扣等）。
Warning
如果需要为了安全地执行程序而佩戴矫正护目镜，请确保护目镜牢固地固定到头上并且不会掉落。
Warning
Always wear High Voltage (HV) gloves and safety glasses when handling any high voltage component, including test equipment. Before each use, test gloves using an authorized glove tester and verify that the testing date on the gloves has not expired.
Warning
All repair and operating instructions should be reviewed and understood before working on Tesla vehicles, associated components, or associated repair equipment.
Warning
Assume that high voltage is present at all times when working on a Tesla vehicle, associated high voltage components, or associated high voltage test equipment until proven otherwise. Be aware that energy states can change during testing, so err on the side of caution.
Warning
Always have an electrical safety hook in the area when working with HV components. Electrical safety hooks are used to remove an injured person from a live high voltage circuit without risking additional injury.
Warning
Use a high voltage digital multimeter to check for the presence of high voltage on both sides of the connector every time a high voltage connector is disconnected. Do not use a
Warning
Make sure that the insulation meter and leads are capable of handling at least 500V DC.
Warning
Obey all instructions when using test equipment or servicing a Tesla vehicle or associated high voltage components. If repair instructions are not clear or if there are any questions about how to use the test equipment, escalate a Toolbox session before proceeding.
Warning
If any test equipment fails to operate as expected, do not attempt to diagnose or repair the vehicle. Follow the appropriate lock out – tag out procedure for the equipment, notify your manager.
Warning
When using test equipment, make sure that all cables are connected before turning equipment on or otherwise initiating use.
Warning
High voltage is present on battery recovery chargers whenever the HV LEDs are lit. However, indicators and LEDs can fail. Do not assume that if an LED is not lit no high voltage is present. Assume high voltage is present at all times until proven otherwise by use of a multimeter.
Warning

Note
This procedure is for 非结构化电池组 7 seat vehicles. For instructions on checking HV disablement on 非结构化电池组 5 seat vehicles, see 车辆高压禁用程序. For instructions on checking HV disablement on 结构化电池组 5 seat vehicles, see 车辆高压禁用程序 （结构化电池组）
  1. Open all the doors and lower all the windows.
  2. Remove the rear underhood apron. See 前备箱挡板 - 后部（拆卸和更换）.
  3. Disconnect 12V/LV power. See 12V/低压电源（断开和连接）.
  4. Set the current clamp to measure voltage , and then measure the voltage across the 12V/LV auxiliary battery terminals using the test probes.
    Note
    For LV (Li-Ion) auxiliary battery: if the voltage across the battery terminals is 0, the battery may have switched off internally. Use a 12V Lead Acid battery for testing. For mobile technicians: use the 12V Lead Acid battery in the Mobile Service vehicle.
    CAUTION
    For LV (Li-Ion) auxiliary battery: if the voltage across the battery terminals is less than 13 volts or greater than 16 volts, the current clamp is not measuring reliably and must not be used.
    CAUTION
    For 12V (Lead Acid) auxiliary battery: if the voltage measured is less than 10 volts or greater than 14 volts, the current clamp is not measuring reliably and must not be used.
  5. Remove the mid aero shield panel. See 面板 - 流线型护板 - 后部（拆卸和更换）.
  6. Remove the rear battery skid plate. See 滑板 - 高压电池 - 后部（拆卸和更换）.
  7. Remove all items from pockets and ensure not wearing metal items.
  8. Inspect HV insulating gloves.
    Note
    Check gloves for damage prior to use, Refer to service document TN-15-92-003 R1, for information on inspecting HV gloves.
  9. Put on HV insulating gloves, leather outer gloves, and safety glasses.
    Warning
    Continue to wear the gloves until instructed to remove them.
  10. Power on the current clamp meter, and then zero out the meter for measurement.
    Warning
    Make sure to set the clamp meter to measure DC amps ("Adc").
  11. Install the current clamp meter onto one cable of the rear drive unit HV harness.
    Note
    Make sure the meter is facing the correct direction.
  12. Measure the current in the HV cable.
    • If the current is within the range of -0.5 A to 0.5 A, continue to the next step.
    • If the current is outside the range of -0.5 A to 0.5 A, for example -0.8 A or 1.3 A, re-perform the LV power disconnect procedure. See 12V/低压电源（断开和连接）. If the measurement is still outside the range of -0.5 A to 0.5 A, escalate for assistance.
      Warning
      DO NOT DISCONNECT any HV harness when the current measurement is outside the range of -0.5 A to 0.5 A.
  13. Remove the nut that attaches the RDU HV cable bracket to the HV battery.
  14. Disconnect the RDU HV cable from the HV header.
    Note
    Release the locking tab, and then rotate the release lever upward to disengage the connector. Do not force the release lever up. Ensure the alignment tabs on the RDU header are not damaged.
  15. Verify no high voltage at the rear drive unit HV header.
    Warning
    为减少可能接触高压的风险，请按照如下顺序测量高压：
    Note
    Verify test equipment is rated CATIII or higher. Measure B+ to Ground, B- to Ground, B+ to B-. If the voltage is greater than 10V, the pack contactors are not open or welded. Stop work and reach out to Service Engineering.
