Car scanner codes

Types of Car Scanner Codes

Car scanner codes are divided into many types, but the main ones are as follows:

• OBD-II Codes

  These are standard codes used for emissions-related issues. They cover a wide range of problems and have a standardized format that is recognized across all car makes and models. OBD-II codes are divided into 5 categories:

  1. Class A: These are codes for emissions-related issues. They do not affect the safety of the driver or the vehicle's operability. Example: Secondary Air System Incorrect Purge Flow.

  2. Class B: These codes indicate issues that could affect the safety of the driver but do not affect the vehicle's operability. Example: Brake Switch Stuck Open.

  3. Class C: These are codes for issues related to the vehicle's safety systems, such as the brakes or airbags. Example: ABS Module Communication Error.

  4. Class D: These codes are for issues related to the vehicle's driveability, such as engine performance problems. Example: Engine Misfire Detected.

  5. Class E: These codes are for issues that cannot be classified into the other categories. Example: Invalid Data Received From Vehicle Equipment.

• Manufacturer-Specific Codes

  These codes are used to diagnose problems that are unique to a particular make or model of car. They are not standardized like OBD-II codes and can vary depending on the manufacturer.

• Generic Codes

  These codes are used for problems that are common across many different makes and models of cars. They are not tied to a specific manufacturer or model, making them useful for mechanics working on a wide range of vehicles.

• Proprietary Codes

  Proprietary codes are used for issues related to the software or electronics of a specific make or model car. They are only accessible using specialized diagnostic tools from the car's manufacturer.

• Communication Protocol Codes

  These codes are used to diagnose problems related to the communication between different electronic modules in a car. They are used by specialized diagnostic equipment to troubleshoot issues with the car's electrical system.

Specification and Maintenance of Car Scanner Codes

Car scanner tools have various specifications that make them unique and suitable for different functions. Here are the general specifications of car scanner codes:

  Car scanner codes get their power from different sources. The common ones include the car's battery through the OBDII port, a built-in rechargeable battery, or the vehicle's 12-volt power outlet. Each power source has its advantages and disadvantages. For instance, a scanner that gets its power from the OBDII port draws power from the car's battery. This means it will drain the battery once the ignition is off.

• Data Transmission

  Data transmission refers to how the scanner communicates with the car's computer. It can either be wireless through Bluetooth and Wi-Fi or wired through an USB or serial cable. Wireless options allow communication with the car's computer from a distance. They are also compatible with modern laptops and phones.

• Functionality

  Different types of car scanners have different functionalities. For instance, some are only designed to read and erase codes, while others can perform advanced functions such as live data streaming, vehicle diagnostics, and programming.

• Compatibility

  Some car scanner codes are designed to work with all cars, while others are only compatible with specific car models. For example, a scanner code that works with all cars needs to comply with the ISO 9141, KWP 2000, or SAE J1850 standards.

• Build Quality

  Some important aspects of an obd scanner tool's build quality are durability and robustness. For instance, a handheld scanner tool needs to be resistant to falls and rough handling, while a car laptop scanner needs to be slim and lightweight.

• Warranty

  Some manufacturers offer a warranty period to ensure that the quality of their car scanners is assured. The warranty period varies depending on the manufacturer, but it is commonly one year.

Below are some of the maintenance tips for a car scanner:

• Always update the scanner's software and firmware to improve its performance and add new features.
