Tesla Model S: Fusebox - Battery (RHD) (Remove and Replace)

Warning: If the 12V power supply is disconnected, do not attempt to open any doors with door glass in closed position. Failure to follow this instruction could result in door glass shatter.

Note: Before disconnecting the 12V power supply, ensure that the driver's door window is fully open. Failure to follow this instruction could result in vehicle lockout.

Removal

1. Remove the 12V battery (refer to procedure).
2. Pull back the LH front upper wheel arch liner for access (refer to procedure). Note: The wheel arch liner does not need to be completely removed.
3. Remove the nut that retains the battery fusebox cover.

   

4. Remove the battery fusebox cover.
5. Record the positions of the small-gauge cables at the RH side of the fusebox.

   

6. Remove the nuts that retain the small-gauge cables and fuses at the RH side of the fusebox (torque 5 Nm).

   Note: After removing the lowest cable, temporarily reinstall the nut loosely. This prevents the bolt from falling out of the back of the fusebox when it is removed.

   

7. Remove the wire separator for access to the inboard cables and fuses.

   

8. Remove the nuts that retain the inboard wires and fuses at the RH side of the fusebox (torque 5 Nm).

   Note: The middle green fuse, fuse F82, is for the air suspension compressor. Vehicles with coil suspension do not have a wire connected to fuse F82.

   

9. Remove the nuts (x2) that secure the pyrotechnic fuse (torque 12 Nm). Disconnect the pyrotechnic fuse connector.

   

10. Remove the pyrotechnic fuse.
11. Remove the nut that secures the DCDC harness to the fusebox (torque 12 Nm).

    

12. Remove the nut that secures the battery positive cable to the fusebox (torque 10 Nm).

    Note: After removing the battery positive cable, temporarily reinstall the nut loosely. This prevents the positive terminal adaptor and square head bolt from falling out of the back of the fusebox when it is removed.

    

13. Remove the nut that secures the fusebox to the fusebox bracket (torque 5 Nm).

    

14. Remove the fusebox.

Installation procedure is the reverse of removal, except for the following:

1. Before installing the fusebox, temporarily install the nut on the battery positive terminal loosely. This prevents the positive terminal adaptor and square head bolt from falling out of the back of the fusebox before it is installed.
2. Before installing the fusebox, temporarily install the nut on lowest small-gauge cable loosely. This prevents the bolt from falling out of the back of the fusebox before it is installed.
