Types of MST300 scanners

An MST300 scanner can come in different variations, each with distinct features and characteristics.

• Bluetooth Car Scanner

  This is an advanced wireless technology that allows a car's computer to be scanned without cable connections. Bluetooth car scanners diagnose vehicle problems by wirelessly connecting to a mobile phone or tablet. This enables the user to read trouble codes, monitor sensor data, reset fault codes, and perform other diagnostic functions. They offer convenience and flexibility compared to traditional wired scanners.

• Full System Scanner

  A full system scanner has comprehensive coverage of a vehicle's systems and modules. Unlike basic or module-specific scanners, full system scanners diagnose and interface with all available vehicle systems. This includes not just engine diagnostics but also systems like transmission, abs, airbag, body control, and more. Advanced features may include live data streaming, active test capabilities, bi-directional control, and access to manufacturer-specific functions and overrides. Full system scanners are typically used by professional technicians who need in-depth access to all of a vehicle's computers for complete troubleshooting and repair.

• Key Programming Scanner

  A key programming scanner is a specialized type of diagnostic tool used to program keys for vehicles that have immobilizer or security systems. When a car is manufactured, the keys are made with unique transponder chips that send specific codes to the car's ignition system. If the codes match, the car will start. If a car owner loses the keys or needs a new one made, the key programming scanner can create a new one by encoding it with the correct transponder chip code for that vehicle. This process requires connecting the key programming scanner to the vehicle's OBD-II port and then linking it to the car's systems to add the new key. Some models of key programming scanners can program keys for multiple vehicle makes and models, making them versatile tools for locksmiths and auto technicians.

• OBD2 Scanner

  The On-Board Diagnostics II (OBD2) scanner is the most well-known car scanner type. It connects to the OBD2 port, usually located underneath the dashboard on the driver's side. The OBD2 port is standardized in most vehicles made after 1996. Using an OBD2 scanner allows access to diagnostics, trouble codes, and data from the vehicle's onboard computer systems. Basic OBD2 scanners can read and clear trouble codes related to engine issues but advanced models may offer more extensive functionalities.

Specification and Maintenance

An automobile diagnostic tool should have specifications that meet the professional needs of users in the auto repair business. The following types of specifications are critical for the Mst300 scanner and other diagnostic scanners for professional use.

• Comprehensive Vehicle Coverage

  A professional auto repair scanner must cover many vehicle makes and models. It should include both domestic and foreign vehicles so that technicians can use one tool to diagnose most of the vehicles that come for repair.

• Advanced Functions

  The scanner should provide advanced functions for a more in-depth analysis of complex vehicle issues. Some of the crucial advanced functions it must possess are these: an actuation test allows technicians to control specific vehicle components and actuators to examine their response; an adaptation program enables the scanner to recalibrate and reprogram learned values after the replacement of modules or sensors; an automatic vehicle identification feature quickly identifies the make and model of a connected vehicle; and service and repair recalls feature gives the technician easy access to manufacturer service bulletins and repair recalls related to a specific vehicle.

• Bidirectional Control

  With the help of the scanner, a technician must be able to send commands to the vehicle's systems and receive responses from them. Examples of areas where this feature will come in handy are active tests of engine components like fuel injectors and cooling fans, tests on actuator systems like throttle actuators and electronic steering, tests on brake systems including anti-lock brake actuators, and calibration of replaced modules or new parts like Electronic Control Units (ECUs) or sensors.

• Data Stream and Live Parameters

  The scanner in question must show real-time data and live parameters from a vehicle’s sensors and actuators. It should monitor critical engine functions such as air intake, fuel pressure, engine temperature, and oxygen sensor readings, among others. In addition to engine parameters, the scanner should also have features for monitoring transmission data, such as gear position, temperature, and slip values; Body Control Module (BCM) data, including door status, window operation, and lighting functions; Anti-lock Brake System (ABS) parameters like wheel speed, brake pressure, and ABS module status; and Airbag Module data including impact sensors, seatbelt sensors, and airbag status.

For the scanner to stay in good operating condition for many years of use, it will require periodic maintenance from time to time. The routine Mst300 scanner maintenance schedule is as follows.

• Regular Software Updates

  Constantly upgrade the scanner software to maintain compatibility with new vehicle models and technologies. Doing so will ensure that technicians have access to the latest diagnostic functions and features.

• Data Backup and Restore

  Always back up diagnostic data, vehicle profiles, and custom settings. Doing so will make it easy to restore the information in case of data loss or system failure. The operator should also create and maintain a log of software updates, diagnostic sessions, and any issues encountered along the way. This log will provide valuable information when troubleshooting or seeking technical support.

• System Diagnostics

  Periodically run a full system diagnostic test on the scanner itself to check for any errors or issues that may be present at that time. The user should also perform hardware inspections on the device. This includes checking all relevant components, cables, connectors, and adapters for any signs of wear, damage, or loose connections that can affect performance.

• Battery Maintenance

  Technicians should calibrate the scanner battery regularly. Doing so will guarantee longevity and reliable performance, even under various conditions. If the scanner battery is detachable, store it in a cool, dry place when it is not in use.

Uses of an MS3100 Code Scanner

The main function of a car diagnostic scanner is to read the codes on the dashboard. But that is not all there is to an engine diagnostic scanner. Here are some other things else how the scanner is used.

• Diagnosing Problems: A diagnostic scanner's primary purpose is to identify issues with a vehicle by reading fault codes generated by its onboard computer. These codes correlate with specific problems, often related to the engine, emission systems, or other critical components. By interpreting these codes, a car scanner can point technicians toward the general area of concern, facilitating faster and more accurate repair.
• Reading Live Data: In addition to retrieving trouble codes, car diagnostic scanners can display live data from various sensors and systems within the vehicle. This real-time information includes details about engine parameters, sensor readings, vehicle speed, temperature, fuel trim, and more. Analyzing this live data allows technicians to monitor the vehicle's functioning in real-time, helping to identify issues that may not trigger a fault code but require attention.
• Recalibrating Tires: Some car scanners can recalibrate the system after performing tire replacements or changes. This ensures that the system is accurate and reflects the vehicle's current tire setup.
• Performing Active Tests: Certain advanced diagnostic scanners can perform active tests, which means they can command specific components or systems to function. For example, a scanner might activate an individual engine or another part to verify its operation. Active testing assists technicians in pinpointing faulty parts that may need to be replaced.
• Maintenance Reset: A car scanner can reset maintenance indicators and service reminders on the dashboard. After completing routine maintenance tasks, resetting these alerts helps maintain proper communication between the vehicle's systems and the driver's information interface.
• Reading Freeze Frame Data: When a fault occurs, the onboard computer may take a snapshot of the data at that specific moment, known as freeze frame data. This information is invaluable for diagnosing intermittent problems, as it provides a snapshot of the vehicle's conditions when the issue arose. An MST scanner can read this freeze-frame data and offer insights into the situation, allowing for more precise diagnostics.
