Tesla Model 3: Procedure (Single - Phase)
SPECIAL TOOLS
Insulation Multimeter, Fluke 1507 (NA) (1076921-00-B)
Insulation Multimeter, Fluke 1587 (EMEA) (1076921-00-A)

Warning: This procedure verifies that high voltage power is no longer available to the charge port. Perform this procedure before servicing any part of the charge port assembly.Warning: Remove all jewelry (watches, bracelets, rings, necklaces, earrings, ID tags, piercings, etc.) from your person, and all objects (keys, coins, pens, pencils, tools, fasteners, etc.) from your pockets before performing any procedure that exposes you to high voltage.
Warning: If corrective eyewear is necessary to safely perform any procedure, make sure that the eyewear is securely restrained to the head and cannot fall off.
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 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.
Warning: Make sure that the insulation meter and leads are capable of handling at least 500V DC.
Procedure (Single-Phase)
- Open the charge port door.
- Disconnect 12V power. See 12V Power (Disconnect and Connect).
- Set the insulation multimeter to measure DC voltage.
- Put on safety glasses, High Voltage (HV) insulating gloves, and leather glove protectors.
- Use the insulation multimeter with slim test probes to check voltages at charge port terminals B+ and B-.
Warning: If the voltage reading is greater than 10V, the HV battery contactors are closed or welded. Stop this procedure and escalate a Toolbox session, as appropriate.
- Attach the insulation multimeter ground connector to the LH rear door latch striker.
- Use the insulation multimeter to check voltages at B+ and ground.
Warning: If the voltage reading is greater than 10V, the HV battery contactors are closed or welded. Stop this procedure and escalate a Toolbox session, as appropriate.
- Use the insulation multimeter to check voltages at B- and ground.
Warning: If the voltage reading is greater than 10V, the HV battery contactors are closed or welded. Stop this procedure and escalate a Toolbox session, as appropriate.
- If all previous voltage readings were less than 10V, return to the procedure that specified the charge port voltage check.

Wearing Seat Belts
Using seat belts and child safety seats is the
most effective way to protect occupants if a
collision occurs. Therefore, wearing a seat belt
is required by law in most jurisdictions.
Both the driver and passenger seats are
equipped with three-point inertia reel seat
belts. Inertia reel belts
