the vast number of test applications and variations in the products that
can be tested with this equipment, we cannot possibly anticipate or
provide advice or safety messages to cover every circumstance. It is the
automotive technician's responsibility to be knowledgeable of the system
being tested. It is crucial to use proper service methods and test
procedures. It is essential to perform tests in an appropriate and
acceptable manner that does not endanger your safety, the safety of
others in the work area, the device being used, or the vehicle being
tested.
Before using the device, always refer to and follow the safety messages
and applicable test procedures provided by the manufacturer of the
vehicle or equipment being tested. Use the device only as described in
this manual. Read, understand, and follow all safety messages and
instructions in this manual.

Safety Warning
Always perform automotive testing in a safe environment.
Wear safety eye protection that meets ANSI standards.
Keep clothing, hair, hands, tools, test equipment, etc. away from all
moving or hot engine parts.
Operate the vehicle in a well-ventilated work area, for exhaust gases
are poisonous.
Put the transmission in PARK (for automatic transmission) or NEUTRAL
(for manual transmission) and make sure the parking brake is engaged.
Put blocks in front of the drive wheels and never leave the vehicle
unattended while testing.
Be extra cautious when working around the ignition coil, distributor cap,
ignition wires and spark plugs. These components create hazardous
voltages when the engine is running.
Keep a fire extinguisher suitable for gasoline, chemical, and electrical
fires nearby.
Do not drive the vehicle and operate the test equipment at the same
time. Any distraction may cause an accident.

Refer to the service manual for the vehicle being serviced and adhere to

special functions.
3.1 Protocol Supported
High Speed CAN - offers baud rates from 40 Kbit/s to 1 Mbit/sec, depend�
ing on cable length. This is the most popular standard for the physical
layer, since it allows for simple cable connection between devices. High
speed CAN networks are terminated with 120 ohm resistors on each end
of the networ
Low Speed CAN - offers baud rates from 40 Kbit/s to 125 Kbits/sec. This
standard allows CAN bus communi�cation to continue in case of a wiring
failure on the CAN bus lines. In low speed CAN networks, each device
has its own termination.
Single CAN - offers baud rates up to 33.3 Kbit/s (up to 88.3 Kbit/s for
high-speed mode)
J1939 CAN - is used in the commercial vehicle area for communication
through�out the vehicle with the physical layer defined in ISO 11898.
Under J1939/11 and J1939/15, the data rate is specified as 250 Kbit/s,
with J1939/14 specifying 500 Kbit/s.
J1850 (PWM) - SAE J1850 pulse-width modulation offers baud rates up
to 41.6 Kbit/s, standard of the Ford Motor Company
J1850 (VPW) - SAE J1850 variable pulse width offers baud rates up to
10.4 Kbit/s, standard of the General Motors
J1708 (SAE) - the standard defines a double-wire 18-gauge cable that
can run upto 130 feet (40 m) and operates at 9600 bit/s
