DIAGNOSTIC TECH
EV TOOL REQUIREMENTS
Love them or hate them, EVs will need service, and even
if you're already servicing these vehicles, there are some
new tools you may want to familiarize yourself with. As
you'll see below, you'll also need to consider how to address
infrastructure charging complaints as well.

ELECTRICAL RELAY CIRCUIT ANALYSIS
When performing diagnostics on various power circuits
controlled via a relay, I usually operate within one or more
of the power distribution centers on the vehicle. This usually
provides us quick access to the problem circuit on the
vehicle without major disassembly. I have a tool that I've
been using for over a decade that has helped me make quick
diagnostic decisions that I'll talk about below.
UACTIVATE FROM AESWAVE.COM
The uActivate comes with various adapters that plug
directly into the same socket your relay-controlled circuit
under test consumes. It makes quick work for checking
relay controls, power, and ground,
and provides one with various test
points. I was informed about the latest
version of this tool and was able to get
my hands on one recently. This tool is
new and improved in several areas, and
I'm impressed. One of the cooler parts
of the tool is that it provides a highcurrent
loop that allows one to connect a
current probe along with shrouded
banana jack connections allowing one to
monitor, measure, and activate circuits
on the vehicle under test.

AUTEL - INTELLIGENT EV DIAGNOSTICS FOR
HYBRID AND BATTERY ELECTRIC VEHICLES (BEVS)
MS909EV/ULTRA EV
Autel has recently introduced a new platform that takes
Hybrid/BEV diagnostics to a new level. From the diagnostic
port, most Hybrids and BEVs have diagnostic info available
but in most cases, that data is limited. Autel's new offering
brings forward a new EV diagnostic capability. Under the
New Energy menu, one has all the modern vehicle scan
functions, including the network topology layout and new
battery cell data that can help with a health assessment.
Additionally, the Battery Pack Test menu includes a highvoltage
system block diagram, which provides guided pathways
for the technician to remove the vehicle connection
to the Battery Management System (BMS) and connect
the scan tool to the new EV Diag. Box. This interfaces
directly with power, ground, and communication circuits
to produce a more granular dataset, including battery state
of charge, health, total voltage, pack voltage delta, temperature,
and more.
This information can help the technician gain a deeper
knowledge of the high-voltage battery pack and controls.
EV CHARGER DIAGNOSTICS
The future will likely introduce problems where a vehicle
cannot charge properly, and there may not be anything wrong
with the vehicle. So how can one test a charger to see if it
works properly? Fluke has introduced a new Electric Vehicle
Service Equipment (EVSE) diagnostic tool that can help you
analyze infrastructure chargers.
