Warning
This procedure is a DRAFT,
although it has been validated. Warnings and Cautions might be missing. Follow safety
requirements and use extreme caution when working on or near high voltage systems and
components. Provide corrections and feedback to ServiceDevelopment@teslamotors.com.
Remove
- Open all the doors and lower all the windows.
- Place the vehicle into Service Mode. See Service Mode.
- Remove the ancillary bay cover. See Cover - Ancillary Bay (Structural Pack) (Remove and Replace).
- Remove the pyrotechnic battery disconnect. See Pyrotechnic Battery Disconnect (Structural Pack) (Remove and Install).
- Release the tabs that secure the 63A fuse cover to the vehicle, and then remove the cover from the assembly.
-
Remove and discard the nuts (x2) that
attach the 63A fuse to the ancillary bay, and then remove the fuse from the ancillary bay.2.5 Nm (1.8 lbs-ft)Tip: Use of the following tool(s) is recommended:

Install
-
Position the 63A fuse into the ancillary bay, and then install new nuts (x2) that attach
the fuse to the ancillary bay.2.5 Nm (1.8 lbs-ft)Tip: Use of the following tool(s) is recommended:
- 8 mm socket
-
Use a Hioki resistance meter to
measure the resistance between the 63A fuse and the terminal.
NoteThe maximum acceptable resistance is 0.105 mΩ (105 μΩ). There is too much resistance in the High Voltage joint. Remove the fastener, clean areas with isopropyl alcohol, install fastener back and test again
