Isolate
- Open all the doors and lower all the windows.
- Remove the rear underhood apron. See 前备箱挡板 - 后部(拆卸和更换).
- Disconnect 12V/LV power. See 12V/低压电源(断开和连接).
-
Set the current clamp to measure
voltage , and then measure the voltage across the 12V/LV auxiliary battery terminals
using the test probes.
注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.警告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.警告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.
- Remove the mid aero shield panel. See 面板 - 流线型护板 - 后部(拆卸和更换).
-
Remove all items from pockets and
ensure not wearing metal items.
-
Inspect HV insulating gloves.
注Check gloves for damage prior to use, Refer to service document TN-15-92-003 R1, for information on inspecting HV gloves.
-
Put on HV insulating gloves, leather
outer gloves, and safety glasses.
警告Continue to wear the gloves until instructed to remove them.
-
Power on the current clamp meter, and
then zero out the meter for measurment.
警告Make sure to set the clamp meter to measure DC amps ("Adc").
-
Install the current clamp meter onto
one cable of the rear drive unit HV harness.
注Make sure the meter is facing the correct direction.
-
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.警告DO NOT DISCONNECT any HV harness when the current measurement is outside the range of -0.5 A to 0.5 A.
-
Disconnect the RDU HV cable from the
HV battery.
注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.
-
Verify no high voltage at the rear drive unit HV header.
警告为减少可能接触高压的风险,请按照如下顺序测量高压:注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.

Return to the procedure that required
the vehicle to be electrically isolated.
警告执行需要对车辆进行电气隔离的程序时,请遵守所有安全指示以及有关个人防护装备 (PPE) 的要求。执行需要处理高压线缆、母排或接头的程序时,请勿脱下高压绝缘手套。注If you are no longer exposed to high voltage, the HV insulating gloves may be removed.
Integrate
-
If removed, put on the HV insulating
gloves and leather over gloves.
-
Connect the RDU HV cable to the HV
battery.
注Verify that the lever is in the upright and open position. Carefully seat the connector and allow the lever to engage. Fully secure the lever and verify that the red tab is locked.
- Remove the leather glove protectors and the HV insulating gloves.
-
Install the mid aero shield panel. See
面板 - 流线型护板 - 后部(拆卸和更换).
注Apply Loctite 222 onto the mid aero shield bolts.
- Connect 12V/LV power. See 12V/低压电源(断开和连接).
- Install the rear underhood apron. See 前备箱挡板 - 后部(拆卸和更换).
- Raise all the windows and close all the doors.
