Warning
This procedure disables LV power, but does not verify that high voltage power is no longer available to high voltage components (A/C compressor, inverters, etc). Perform Vehicle HV Disablement Procedure after this procedure, and before servicing high voltage components.
Warning
Failure to follow the exact order of steps in this procedure may cause permanent damage to the car computer.
CAUTION
Before disconnecting the LV power, make sure windows are not moved for at least 1 minute. Failure to wait before disconnecting can result in component damage.

Disconnect

  1. Disconnect any charging cable.
  2. On the touchscreen, power off the climate control system, and wait at least 30 seconds for the climate control system to completely shut down.
  3. Make sure the vehicle is in Park.
  4. Open all doors and lower the windows.
  5. Open the LH and RH rear doors, and then pass a shop towel halfway through each door striker to prevent the latch from securing.
  6. Remove the HEPA filter or cowl assembly. See HEPA Filter Assembly (Remove and Replace) or GUID-DBC8475C-F7BA-4A10-9234-C810D77D3F90.html.
  7. Power off the vehicle from the center display.
    Note

  9. Disconnect the first responder loop.
    Note
    Before proceeding to service the vehicle, allow 2 minutes for all electrical circuits to discharge.
  10. If LV power was disconnected to service a high voltage component, verify that high voltage power is no longer available to that component. See Vehicle HV Disablement Procedure.

Connect

  1. Connect the first responder loop.
    CAUTION
    Connect the first responder loop BEFORE connecting the LV battery connector.
