Precautions on Using X-431 Torque
Before using this test equipment, please read the following safety information
carefully.
 Always perform automotive testing in a safe environment.
 If the diagnostic connector remains unused for a long period of time, it is
suggested to unplug the connector from vehicle’s DLC to conserve battery
power.
 Wear an ANSI-approved eye shield when testing or repairing vehicles.
 The vehicle shall be tested in a well-ventilated work area, as engines produce
various poisonous compounds (hydrocarbon, carbon monoxide, nitrogen
oxides, etc.)
 Do not connect or disconnect any test equipment while the ignition is on or
the engine is running.
 Put blocks in front of the drive wheels and never leave the vehicle unattended
while testing.
 Keep the test equipment dry, clean, free from oil, water or grease. Use a mild
detergent on a clean cloth to clear the outside of the equipment as
necessary.
 Do not drive the vehicle and operate the test equipment at the same time.
Any distraction may cause an accident.
 Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or
hot engine parts.
 Before starting the engine, put the gear lever in the Neutral position (for
manual transmission) or in the Park (for automatic transmission) position to
avoid injury.
 To avoid damaging the test equipment or generating false data, please make
sure the vehicle battery is fully charged and the connection to the vehicle
DLC (Data Link Connector) is clear and secure.
 Automotive batteries contain sulfuric acid that is harmful to skin. In operation,
direct contact with the automotive batteries should be avoided. Keep the
ignition sources away from the battery at all times.
Precautions on Operating Vehicle’s ECU
 Do not disconnect battery or any wiring cables in the vehicle when the ignition
switch is on, as this could avoid damage to the sensors or the ECU.
 Do not place any magnetic objects near the ECU. Disconnect the power
supply to the ECU before performing any welding operations on the vehicle.

iv
 Use extreme caution when performing any operations near the ECU or
sensors. Ground yourself when you disassemble PROM, otherwise ECU and
sensors can be damaged by static electricity.
 When reconnecting the ECU harness connector, be sure it is attached firmly,
otherwise electronic elements, such as ICs inside the ECU, can be damaged.
