Tesla Model S: HV Junction Box - Cover - 1st Generation (Remove and Replace)
Warning: Only technicians who have been trained in High
Voltage Awareness are permitted to perform this procedure. Proper
personal protective equipment (PPE) and insulating HV gloves with a
minimum rating of class 00 (500V) must be worn any time a high
voltage cable is handled. Refer to Tech Note TN-15-92-003, "High
Voltage Awareness Care Points" for additional safety information.
Removal
- Disconnect 12V and HV power:
- Rear wheel drive (RWD): Refer to procedure.
- Dual Motor: Refer to procedure.
- Remove the 2nd row cushion frame (refer to procedure).
Warning: Proper personal protective equipment (PPE) and
insulating HV gloves with a minimum rating of class 00 (500V) must
be worn while performing the remainder of this procedure.
Warning: Ensure that the multimeter and leads are capable
of handling at least 500V.
- Remove the bolts (x6) that secure the HV junction box cover
(torque 5 Nm). Remove the cover.
- Use a multimeter to check voltages across the HV cables and to
ground:
- B+ to ground
- B- to ground
- B+ to B-
Warning: If any voltage reading is more than 10V, the high
voltage contactors are not fully opened. Due to the risk of
electrocution, contact Service Engineering before performing
any further work.
