Isolation/Insulation Test (Test/Adjust)

Correction code 44000100 FRT 0.05 NOTE: Unless otherwise explicitly stated in the procedure, the correction code and FRT listed above 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. NOTE: See Personal Protection to make sure you are wearing proper PPE when performing the procedure below. NOTE: See Ergonomic Precautions for safe and healthy working practices.

Perform the isolation/insulation test when diagnosis requires verification that a circuit or component is properly isolated, or a cable has sufficient insulation.

Warning
When measuring isolation/insulation, the tester will generate high DC voltage up to 1000V. Proper HV PPE must be worn when performing an isolation/insulation test.

Warning
Residual voltage may still be present in the component after performing an isolation/insulation test – DO NOT TOUCH THE COMPONENT WITHOUT FIRST CHECKING THE VOLTAGE after an isolation/insulation test.

Warning
Always wear High Voltage (HV) gloves and safety glasses when handling any high voltage component, including test equipment. Before each use, test gloves using an authorized glove tester and verify that the testing date on the gloves has not expired.

Warning
Assume that high voltage is present at all times when working on a Tesla vehicle, associated high voltage components, or associated high voltage test equipment until proven otherwise. Be aware that energy states can change during testing, so err on the side of caution.

Warning
Always have an electrical safety hook in the area when working with HV components. Electrical safety hooks are used to remove an injured person from a live high voltage circuit without risking additional injury.

Warning
Obey all instructions when using test equipment or servicing a Tesla vehicle or associated high voltage components. If repair instructions are not clear or if there are any questions about how to use the test equipment, escalate a Toolbox session before proceeding.

Warning

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.
