than seven percent of its service industry has the qualifications

requirements for those working on these high-voltage systems.
Additionally, there are specific guidelines on how PPE is checked
and validated prior to use. Some items such as gloves have a shelf
life and will need to be recertified on time. Typically, one will
usually find performing general services do not require the use
of the high voltage PPE which is usually limited to direct work
with the vehicle's energy storage system (ESS). BEVs/hybrids
and the like went through a ton of engineering design that meets
several standards through SAE and ISO. These standards have
resulted in vehicle platforms that have very good safeguards in
place to prevent harm to vehicle operators and service personnel.
However, service precautions should always be adhered to in
order to stay safe. It's important to seek out and use the correct
tooling, as well. The proper category rated (CAT) equipment as
defined by the International Electrotechnical Commission (IEC)
61010 standard should be top of mind when choosing the proper
tooling and equipment for work on hybrid and electric vehicles.
The CAT ratings are in place to define how much voltage the tool
can tolerate without causing any damage or harm.
CAT ratings for tools and test equipment should typically
meet either a CAT III or CAT IV level depending on the requirements.
My multimeter of choice is Fluke as I have found them
to be highly reliable devices for decades in my shop. The table
in Figure 4 outlines the voltage levels.
Your test equipment and test leads need to not only meet the
rating requirements but should be closely inspected for damage
prior to each use. Do not use test leads that don't have the requirements
needed to keep you safe. Frayed or damaged test leads can
be a hazard and you don't want to end up as a statistic. And as
mentioned earlier, you will want to make sure that you're equipped
with the proper diagnostic tools such as a highly capable scan tool
and the ability to carry out module programming operations.
If you're working on a specific carline, an OEM-specific
scan tool may be the right choice. For example, if you're working
on Toyota/Lexus automobiles, then you should look at their
Techstream offering. For a low annual fee and an inexpensive but
very capable J2534 interface such as the Mongoose-Plus offered by
Opus, one will have the same capabilities dealership technicians
have access to. The Techstream subscription provides one access
to a PC-based scan tool, reprogramming, and service information.
Note: Although some vehicles today are supported with overthe-air
updating capabilities, there will still be instances where the
service technician will be required to initiate firmware changes
locally with external 12V support systems attached to the vehicle.
