Correction code 17010400 0.06 NOTE: Unless otherwise explicitly stated in the procedure, the correction code and its associated FRT reflect all of the work required to perform this procedure, including the linked procedures. Do not stack correction codes unless explicitly told to do so. NOTE: See Flat Rate Times to learn more about FRTs and how they are created. NOTE: See Personal Protection to make sure you are wearing proper PPE when performing the procedure below. NOTE: See Ergonomic Precautions for safe and healthy working practices.

  • 2025-10-30: Added a caution to make sure windows are not moved for at least 1 minute before disconnecting the 12V/LV power.
  • 2025-10-16: Updated steps to connect/disconnect LV battery connector.
  • 2024-05-15: Added steps to disconnect charging cable and shut down HVAC.
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 (Test/Adjust) 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 12V/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 from the vehicle.
  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. Open all doors and lower the windows.
  4. Open the LH and RH rear doors, and then pass a shop towel halfway through each door striker to prevent the latch from securing.
  5. Remove the rear apron. See Underhood Apron - Rear (Remove and Replace).
  6. Power off the vehicle from the center display.
    Note
    On the touchscreen, touch Controls > Safety > Power Off > Power Off.
  7. Disconnect the LV battery connector from the LV battery.
    1. Release the green locking tab by pulling it outwards (1).
    2. Press the black locking tab numbered as "1" (2A), and then pull the black connector lock outwards (2B).
    3. Press the black locking tab numbered as "2" (3A), and then pull the black connector lock even further outwards (3B) to fully release the connector.
    4. Pull the connector upwards to release it from the LV battery.
  8. Disconnect the first responder loop.
    Note
    Before proceeding to service the vehicle, allow 2 minutes for all electrical circuits to discharge.
  9. 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 (Test/Adjust).

Connect

  1. Connect the first responder loop.
    CAUTION
    Connect the first responder loop BEFORE connecting the LV battery connector.
  2. Connect the LV battery connector to the LV battery.
    1. Connect the connector to the LV battery (1).
    2. Push the black connector lock fully inwards (2).
    3. Push the green locking tab inwards (3) to lock the connector.
  3. Install the rear apron. See Underhood Apron - Rear (Remove and Replace).
  4. Return the windows, seats, climate control, audio, and charging to the state before service.
  5. Close all doors.
