Carry out Diagnostic Procedures
1. Wear safety eye protection that meets ANSI standards, glasses or mask to protect eyes from flying particles and liquid sprays , gloves for handling hot items and chemicals, suitable neat-fitting overalls or clothing, safety footwear.
Wear a mask and face shield before Operating the vehicle in a well-ventilated work area: Exhaust gases are poisonous.
Don’t connect or disconnect any test equipment while the ignition is on or the engine is running.
Keep the scan tool dry, clean, free from oil/water or grease. Use a mild detergent on a clean cloth to clean the outside of the scan tool, when necessary
Keep clothing, hair, hands, tools, test equipment, etc. Away from all moving or hot engine parts
2. Before removing EFI wiring connectors, terminals, etc., first disconnect the power by either turning the ignition switch OFF or disconnecting the negative (-) terminal cable from the battery. HINT: Always check the diagnostic trouble code before disconnecting the negative (-) terminal cable from the battery.
Do not smoke or work near an open flame when working on the fuel system.
Keep gasoline away from rubber or leather parts.
3. Risk of short circuits and burns. Batteries can produce a short circuit current high enough to weld jewelry to metal. Remove jewelry such as rings, bracelets, and watches before working near batteries.
4. Keep hands clear of all moving parts. Use extreme caution, as these may strike you, fling objects, start unexpectedly, or catch dangling leads or strings. Avoid touching hot parts. To work on the drive line, shafts or axles, the street rod must be lifted up. Use the correct procedure when lifting the vehicle on a hoist. Also, if you don’t have a vehicle lift, always use jack stands to support the vehicle safely. Be careful not to crush your fingers or hand when the differential is being removed, disassembled, or reinstalled. Never try to lift heavy drivelines or differentials without proper lifting equipment and specialized jacks. Always wear OSHA-approved safety glasses when working on drivelines, differentials, and axle components.

6. There are multiple precautions that should be followed while working on diagnosis. An accident could occur due to any carelessness or misconduct. Some of the necessary precautions are as follows:
Never leave tools on the battery, where they might short the terminals and create a spark
Wear eye protection when your eyes are at risk, such as when you grind, or drill upside down
Keep a fire extinguisher near your working space.
Make sure that all electrical components are switched off when you remove the strap, otherwise a spark may occur, which could cause the battery to explode.
Never trust a jack. Rather buy some sturdy stands and use them whenever you need to crawl underneath the car.
7. Connect an exhaust gas scavenger system to the vehicle tailpipe when static running, particularly when working in a vehicle inspection pit. It should ventilate to a safe place in the open air – where fume will not be drawn back into the workshop or affect other premises or people nearby. Maintain couplings and flexible connections in good condition to prevent leaks.
8. Open questions ask for more information and encourage the customer to expand on what they have been telling you
9. Closed questions ask for specific information from the customer and typically receive yes/no type responses. I
10. Discover and understand the problem. Collect the information regarding the issue is important for the accurate analysis.
11. Investigation or analysis of the cause or nature of a condition, situation, or problem. A procedure is a logical set of steps to follow. Using a logical procedure will help to diagnose a vehicle’s problem quickly and efficiently. All diagnostic techniques are based on logical thinking and a systematic approach to solving the problem. They often take the form of a diagram or flow chart.

13. A flowchart is a picture of the separate steps of a process in sequential order. It is a generic tool that can be adapted for a wide variety of purposes, and can be used to describe various processes, such as a manufacturing process, an administrative or service...
