1. SAFETY
WARNING! To prevent personal injury or damage to vehicles and/or the scan tool, read this instruction manual first and observe the
following safety precautions.
Always perform automotive testing in a safe environment.
Wear safety eye protection.
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. Exhaust gases are poisonous.
Put blocks in front of the drive wheels and never leave the vehicle unattended while running tests.
Use extreme caution when working around the ignition coil, distributor cap, ignition wires and spark plugs. These components
create hazardous voltages when the engine is running.
Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual transmission) and make sure the parking brake
is engaged.
Keep a fire extinguisher suitable for petrol/chemical/electrical fires nearby.
DO NOT connect or disconnect any test equipment while the ignition is on or the engine is running.

4. USING THE SCAN TOOL
4.1. LOCATION OF THE DLC
4.1.1. The DLC (Data Link Connector or Diagnostic Link Connector) is the standardized 16-cavity connector where diagnostic scan tools
interface with the vehicle's on-board computer. The DLC is usually located 300mm from the center of the instrument panel (dash),
under or around the driver's side for most vehicles. If Data Link Connector is not located under dashboard, a label should be there
telling the location. For some Asian and European vehicles, the DLC is located behind the ashtray and the ashtray must be
removed to access the connector. If the DLC cannot be found, refer to the vehicle's service manual for the location.
4.2. TOOL DESCRIPTION
4.3. FUNCTION DESCRIPTION
