The On-Board Diagnostics II (OBD2) system is a standardized system implemented in all cars and light trucks manufactured after 1996 in the United States. Its primary purpose is to monitor the vehicle’s emissions systems and ensure they are operating within acceptable limits. The OBD2 system also monitors other critical vehicle parameters, such as engine performance, fuel efficiency, and transmission operation.

The OBD2 system consists of several components:

• Sensors: Various sensors are strategically placed throughout the vehicle to monitor different parameters. These sensors include oxygen sensors, mass airflow sensors, coolant temperature sensors, and throttle position sensors.
• Engine Control Unit (ECU): The ECU is the “brain” of the OBD2 system. It receives data from the sensors, analyzes it, and makes adjustments to the engine and other systems to optimize performance and minimize emissions.
• Diagnostic Trouble Codes (DTCs): When the ECU detects a problem, it stores a DTC in its memory. Each DTC corresponds to a specific problem or fault.
• Diagnostic Connector: The diagnostic connector, also known as the OBD2 port, is a standardized connector that allows external devices, such as scanners, to communicate with the ECU.

4.2 Connecting the Scanner to the Vehicle

The Konnwei OBD2 scanner code reader connects to the vehicle via the diagnostic connector. The connector is typically located under the dashboard on the driver’s side. Once the scanner is connected, it can communicate with the ECU and retrieve data.

4.3 Reading and Interpreting DTCs

When the scanner requests DTCs from the ECU, the ECU responds by sending a list of stored codes. The scanner then displays the codes on its screen, along with their definitions.

DTCs are five-character codes that follow a specific format:

• First Character: Indicates the system that the code relates to:
  • P: Powertrain (engine, transmission)
  • B: Body (airbags, power windows)
  • C: Chassis (ABS, suspension)
  • U: Network (communication)
• Second Character: Indicates whether the code is generic or manufacturer-specific:
  • 0: Generic (standardized across all manufacturers)
  • 1: Manufacturer-Specific (unique to a particular manufacturer)
• Third Character: Indicates the specific subsystem that the code relates to:
  • 1: Fuel and Air Metering
  • 2: Fuel and Air Metering (Injector Circuit)
  • 3: Ignition System or Misfire
  • 4: Auxiliary Emission Controls
  • 5: Vehicle Speed Controls and Idle Control System
  • 6: Computer Output Circuit
  • 7: Transmission
  • 8: Transmission
• Fourth and Fifth Characters: Indicate the specific fault within the subsystem.

For example, the DTC P0171 indicates a generic powertrain code related to fuel and air metering. Specifically, it means that the system is “too lean” (too much air, not enough fuel).

4.4 Using Live Data and Freeze Frame Data

In addition to reading DTCs, the Konnwei OBD2 scanner code reader can also display live data from the vehicle’s sensors. This data can be used to monitor the performance of various systems and identify potential problems.
