    Cluttered benches and dark areas may cause accidents.
  2. Do not connect or disconnect the Code Reader while the ignition is on or the engine is running.
  3. DO NOT attempt to operate the Code Reader while driving the vehicle. Have a passenger operate the Code Reader.
  4. Before testing a vehicle, engage the parking brake and chock the tires.
  5. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
  6. Carbon Monoxide is produced while the vehicle’s engine is operating and is deadly in a closed environment. Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness, or nausea. If you have these signs, the work area may not be vented properly. Get fresh air immediately. Operate the vehicle in a well-ventilated work area.

Working Voltage 12 V DC provided by vehicle battery


OBD II On-Board Diagnostics
It is required by the EPA that all 1996 and newer vehicles sold in the United States be equipped with an OBD II computer system.
OBD II is an early warning system designed to monitor engine, transmission, and emissions control components by performing specific diagnostic tests.
When a fault condition is detected, the system captures important data and activates the “Check Engine” light.
If the light comes on, the vehicle might have a condition that wastes fuel, shortens engine life, or causes excessive air pollution. If the problem that caused the light to come on is addressed, for instance a loose gas cap is tightened, the light will go out.
If the light comes on and stays on, a minor engine fault condition is occurring and should be addressed as soon as possible
If the light is blinking, a severe engine fault condition is occurring and should be addressed immediately.
The Code Reader connects to the vehicle’s computer system and captures information that can help identify the fault condition.
