System Diagnostics

The heart of a car diagnostic lies in the Onboard Diagnostics (OBD) system. Our team is proficient with this system and solving your problem.

  1. Components:

    • Diagnostic Link Connector (DLC): This is the port usually located under the dashboard, near the driver’s seat, where a diagnostic scan tool can be connected to access the vehicle’s onboard computer system.
    • Onboard Computer: The vehicle’s onboard computer or Engine Control Module (ECM) continuously monitors various sensors and systems, including engine performance, emissions control, transmission, and more.
    • Sensors: OBD systems rely on numerous sensors throughout the vehicle to collect data on parameters such as engine speed, airflow, oxygen levels, temperature, and vehicle speed.
    • Diagnostic Trouble Codes (DTCs): When the onboard computer detects a problem, it generates diagnostic trouble codes, which are alphanumeric codes that indicate specific issues or malfunctions. These codes provide valuable information for diagnosing and repairing problems.
    • Check Engine Light (CEL): When a fault is detected, the OBD system typically illuminates the check engine light on the vehicle’s dashboard to alert the driver to the issue.
  2. Functions:

    • Monitoring Emissions: OBD systems continuously monitor emissions-related components and systems to ensure compliance with environmental regulations.
    • Diagnostic Capability: OBD systems can detect a wide range of issues, including engine misfires, faulty sensors, exhaust system problems, and more.
    • Data Logging: Some OBD systems can record data over time, allowing mechanics to analyze vehicle performance trends and diagnose intermittent issues.
    • Readiness Monitors: OBD-II systems feature readiness monitors that assess the status of various emissions-related systems, indicating whether they have completed self-diagnostic tests.
  3. Diagnostic Tools:

    • Scan Tools: These handheld devices or software applications can interface with the vehicle’s OBD system to read diagnostic trouble codes, view sensor data, and perform diagnostic tests.
    • Code Readers: Basic code readers can retrieve and display diagnostic trouble codes but may have limited functionality compared to more advanced scan tools.
    • Diagnostic Software: Advanced diagnostic software is available for use with laptop computers or mobile devices, offering comprehensive diagnostic capabilities and data analysis features.
