Correction code 16304026 0.54 NOTE: Unless otherwise explicitly stated in the procedure, the above correction code and 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. To provide feedback on FRT values, email LaborTimeFeedback@tesla.com. NOTE: See Personal Protection to make sure wearing proper PPE when performing the below procedure.

Only
technicians who have been trained in High Voltage Awareness and
have completed all required certification courses (if applicable) are permitted to
perform this procedure. Proper personal protective equipment
(PPE) and insulating HV gloves with a minimum rating
of class 0 (1000V) must be worn at all times a high voltage
cable, busbar, or fitting is handled. Refer to Tech Note TN-15-92-003, High Voltage Awareness
Care Points
for additional safety
information.
Install
- Perform a zero adjust of the Hioki resistance meter in preparation to measure resistances later in this procedure. See Resistance Meter (Zero Adjust).
-
With the new HV battery on a
battery table, remove the HV battery ancillary bay cover. See Cover - Ancillary Bay (Remove and Replace) for
guidance.
WarningIt is not necessary to perform the electrical isolation test on the new HV battery, but continue to follow all warnings and HV safety guidance.
- Remove the pyrotechnic battery disconnect. See Pyrotechnic Battery Disconnect (Remove and Replace).
- Raise the high voltage controller, release the clips that attach the fuse access insulator to the RH ancillary bay bus cover, and remove the insulator.
-
Install the PTC heater fuse
to the RH ancillary bay bus, and then install new nuts to attach the fuse to the
bus.
-
Use the Hioki resistance
meter to measure the resistance at the HV joint between the ancillary bay bus
and the LH side of the PTC heater fuse body .
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
-
Use the Hioki resistance
meter to measure the resistance at the HV joint between the RH side of the
PTC heater fuse and the respective ring terminal plating.
NoteThe maximum acceptable resistance is 0.145 mΩ (145 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
- Install the fuse access insulator on the RH ancillary bay bus cover, fasten the clips that attach the insulator to the cover, and lower the high voltage controller.
- Measure the voltage across the pyrotechnic battery disconnect mount points, and then install the pyrotechnic battery disconnect. See Pyrotechnic Battery Disconnect (Remove and Replace).
- Install the HV battery ancillary bay cover. See Cover - Ancillary Bay (Remove and Replace) for guidance.
- Return to the procedure that requested installation of the cabin heater fuse.
