Types of Vehicle Diagnostics Vehicle diagnostics can be used to determine the cause of a variety of issues with a vehicle. There are different types of diagnostic tools and the service technician will select the appropriate one based on the particular situation and current technical condition. OBD-II, CANBUS are two examples of these tools. Making use of the appropriate tool for the job can help the technician identify the issue and make repairs needed. OBD-II OBD-II vehicle diagnostics are carried out with the use of sensors to identify problems with vehicles. diagnostic checks transmit abnormal data to the vehicle's engine controller unit (ECU), who stores it as a Diagnostic Trouble Code. The code is a string containing numbers and letters that indicates the nature and cause of the problem. OBD-II codes are applicable to all areas of a car, including the chassis, body, powertrain, and network. There are a variety of tools that can be used to perform OBD-II vehicle diagnostics. These tools be as basic as consumer-grade tools to more sophisticated OEM dealership tools and vehicle remote systems. The most basic tools comprise hand-held scanners and fault code readers. However, there are sophisticated and rugged devices available in the market. A scan tool reads the diagnostic trouble codes that are stored in a vehicle's computer system. It can also read the VIN of the vehicle. OBD-II scanners also come with a feature that allows them to read codes from any protocol. The data can be read and understood by mechanics and provide you with information about your vehicle's problem. OBD-II diagnostics for vehicles are an excellent method to save money and improve your car's performance. They also provide details about the health of key engine components and emission controls. This information is helpful in diagnosing issues quickly and easily. CANBUS A scanner tool can be employed to analyze the entire system of any vehicle that is CANBUS conforming. This will allow you to see what modules are supposed to be connected and which are not. This could indicate that there is a problem with wiring or the communication. CAN bus problems can present a variety of signs, such as complete or partial loss of vehicle functionality. These issues can cause an audible warning or visual sign for the vehicle operator. Software errors may be a cause. A CAN bus fault could also lead to a defective charging system, low battery voltage, or insufficient connections. Low resistance readings at CAN ports are an indication of a damaged CAN or wiring harness. Some CAN devices may contain an internal termination resistor that turns on and off as the device starts up. The service data provided by the manufacturer should include information about the internal termination resistors that are unique to a Can device. The CAN bus protocol is a protocol based on messages that is designed to allow communication between automotive components. Multiplex electrical wiring is used to reduce copper consumption and facilitate communication between vehicles. Each device transmits data within a frame that is then received by all other devices in the network. Check engine light A Check engine light on your car could be a sign of a serious problem. You should immediately get your car checked in the event that you see an red or orange light. It will cost you less to fix it the faster you fix it. This light may be accompanied by additional signs, like a strange engine noise. The Check Engine Light, regardless of the reason it is designed to inform you of a problem with your vehicle. This engine-shaped orange icon is typically located in the instrument cluster and it comes on when the car's onboard computer detects any issue. This indicator can be triggered by a variety of problems however, sometimes it's as simple as a leaky gas cap or a defective spark plug. Another reason for the Check Engine Light is a problem with the exhaust system. This light can be caused by an EGR (exhaust gas recirculation valve). These valves don't require regular maintenance , but they can become blocked with carbon and require to be replaced. EGR valves that aren't working properly could also result in more emissions. After you have resolved the issue, your car will automatically stop the light. If your car's CEL is on for more than three days, you may want to check it again, or manually reset the light. A diagnostic scan will reveal the problems that are causing your Check Engine Light to come on. Sometimes, a simple scan using an ordinary scan tool will find the cause. For more complex problems, you'll need to use an expert scan tool. Troubleshooting diagnostic codes Diagnostic trouble codes, also known as DTCs are digits that are that describe the issue in your vehicle. These codes range in length between one and five characters and can represent anything from a warning light to a malfunctioning engine. These codes can be used to troubleshoot and pinpointing the root of the problem. Although DTCs are used to identify car problems but not all are serious. Sometimes, trouble codes signal that the sensor circuit is not functioning properly or that there is an issue with the emissions control system. Once you have identified the root of the problem you can begin figuring out the solution. It is important to know where the trouble codes are located in your vehicle. Typically, DTCs are stored in the Engine Control Module (ECM) or the Powertrain Control Module (PCM). Diagnostic trouble codes are important in determining the type of problem is causing the problem. These codes can aid a mechanic to identify the problem and determine the best option for action. For example, the check engine light may be a sign of a problem with the circuit that controls the fuel level. It could also indicate an issue with the emissions idle control system. In other instances, the light can be a sign of something more serious, for instance, a loose gas cap. Certain codes can be dangerous and need to be fixed immediately. If you have more than one DTC in your vehicle, it is important to identify which is more serious and urgent to fix. Checking fuel supply The volume and pressure of the fuel can be an important aspect of vehicle diagnostics. A malfunctioning fuel pump can cause trouble codes to show on your vehicle's computer. These codes can be interpreted using code readers, or a scan tool. Many auto parts stores provide code reading for free. Additionally, you can purchase cheap code reading devices for your smartphone. Once you've learned what to look for, you can begin taking a look at the pressure inside your fuel system. The process of checking the fuel supply is a step-by-step procedure. It's simple to perform. The first step in evaluating the fuel system is to listen for a humming sound. It should last for around 2 seconds and then stop. If you hear a hum it is likely that the electrical circuit inside your fuel pump is operating in a proper manner. If it's not, then you will need to run additional diagnostic tests. In addition to monitoring the fuel pressure You can also examine the MAF sensor for leaks and blocked fuel injectors. A damaged MAF sensor could be the cause of the P0171/P0174 codes. If you aren't sure what part to replace then you can use an efficiency chart for volumetric measurements or calculator to determine which one. Checking fuel pressure is essential to your vehicle's health. If your car isn't starting properly, even though the pressure is high, it will experience difficulty getting started. A voltmeter reading that indicates low pressure can be indicative of poor fuel flow. You can check the ampage and voltage of the injector pulses by using a scope and an amp clamp. Checking the air filter Filters that are dirty could cause many issues in your car, including rapid acceleration, fuel that is not burned and mini explosions. A thorough inspection of the air filter can help you detect the issues early, and you may be able to notice them before your car shows any symptoms. Start by removing all the fasteners that connect the air intake box together. These fasteners may be clips, screws or even hex nuts. Once the fasteners are removed you can take the air filter out. Make sure that the filter is clean and properly seated. This will enable the filter to perform its functions properly. If the filter is not clean the engine will not perform as it should and may not give you an accurate reading. The air filter is typically located close to the engine or near the front of the vehicle. A blocked air filter may cause the check engine light to flash. This indicator could also signal something more serious. A blocked air filter restricts the flow of air into the engine, which can result in excessive fuel being burned. The check engine light could be triggered by excessive carbon deposits. A skilled mechanic will be able identify the reason for the check engine light. Changing the air filter is an essential component of a car's engine. It stops dust and impurities from getting into the air of the engine. This leads to cleaner combustion. Without proper airflow your engine could have difficulty starting, running, and accelerating.
