Safety First!
It is important that every user utilizing this product read all instructions and warnings included within this manual to ensure
your safety, the safety of others, and to prevent damage to this product & vehicles being diagnosed and repaired. This
manual describes common test procedures used by experienced service technicians. It is inferred that the user has a good
understanding of vehicle systems before using this product.
Many test procedures require precautions to avoid accidents that can result in personal injury, and/or damage to your
vehicle or test equipment. At a minimum, the following safety standards should be followed whenever using this product,
or whenever working on a vehicle.
When an engine is running, it produces carbon monoxide, a toxic and poisonous gas. To prevent
serious injury or death from carbon monoxide poisoning, operate the vehicle ONLY in a well-
ventilated area.
To protect your eyes from propelled objects as well as hot or caustic liquids, always wear approved
safety eye protection.
When an engine is running, many parts (such as the coolant fan, pulleys, fan belt etc.) turn at high
speed. To avoid serious injury, always be aware of moving parts. Keep a safe distance from these
parts as well as other potentially moving objects.
Engine parts become very hot when the engine is running. To prevent severe burns, avoid contact
with hot engine parts.
Before starting an engine for testing or troubleshooting, make sure the parking brake is engaged.
Put the transmission in park (for automatic transmission) or neutral (for manual transmission).
Block the drive wheels with suitable tire blocks.
Connecting or disconnecting test equipment when the ignition is ON can damage test equipment
and the vehicle’s electronic components. Turn the ignition OFF before connecting the tablet to
or disconnecting the tablet from the vehicle’s Data Link Connector (DLC).
To prevent damage to the on-board computer when taking vehicle electrical measurements,
always use a digital multimeter with at least 10 Megohms of impedance.
Fuel and battery vapors are highly ammable. To prevent an explosion, keep all sparks, heated
items, and open ames away from the battery and fuel vapors. DO NOT SMOKE NEAR THE
VEHICLE DURING TESTING.
Don’t wear loose clothing or jewelry when working on an engine. Loose clothing can become
caught in the fan, pulleys, belts, etc. Jewelry is highly conductive and can cause a severe burn if it
makes contact between a power source and ground.
