A car diagnostic involves using specialised tools and equipment to assess the performance and health of a vehicle’s electronic and mechanical systems. The process typically includes:
- Plugging into the OBD-II Port: The diagnostic tool is connected to the car's onboard diagnostics (OBD-II) port. This port is standard in most vehicles made after 1996 and allows us to communicate with the vehicle's electronic control unit (ECU).
- Reading Fault Codes: The diagnostic tool scans the car’s ECU for stored trouble codes. These codes are generated when the vehicle detects a malfunction or anomaly in one of its systems, such as the engine, transmission, brakes, or emissions.
- Analysing Data: The diagnostic tool provides real-time data on various vehicle systems, including fuel efficiency, engine temperature, air and fuel ratios, and more. This data helps identify any underlying issues, even if they haven't triggered a warning light yet.
- Clearing Fault Codes: After identifying and fixing the issue, the technician can clear the fault codes stored in the ECU. If the problem persists, the code may reappear, indicating further investigation is needed.
- Providing a Report: The diagnostic service will generate a report detailing any issues found, the severity of the problem, and recommended repairs or maintenance.
This process helps detect issues early, prevents major breakdowns, and ensures the vehicle runs smoothly. It’s especially useful for understanding complex problems in modern vehicles, which rely heavily on electronic systems.
When your car's check engine light (CEL) comes on, it means the vehicle's onboard diagnostics system (OBD-II) has detected a problem with the engine or related components. The severity of the issue can vary, but here's what typically happens when this light illuminates:
1. Check the Nature of the Light
- Steady Light: A steady check engine light usually indicates a less severe issue, but it still requires attention. This could be something like a loose gas cap, minor engine performance issues, or a faulty sensor.
- Flashing Light: A flashing or blinking check engine light often signals a more serious problem, such as a misfire in the engine, which could cause damage if not addressed quickly.
2. Basic Troubleshooting
Monitor the Car’s Performance: Pay attention to any unusual noises, vibrations, reduced power, or poor fuel efficiency. These symptoms can help identify the severity of the issue.3. Resetting the Light
Once the issue is diagnosed and fixed, the mechanic will reset the check engine light. If the underlying problem hasn’t been fully addressed, the light may return.
Consequences of Ignoring the Check Engine Light:
- Damage to the Engine: Ignoring a flashing CEL can lead to significant engine damage or failure.
- Poor Performance: Problems that trigger the check engine light often affect fuel efficiency, emissions, and overall performance.
- Failed Emissions Test: In many places, a car will fail an emissions test if the check engine light is on, meaning it won't pass inspection until the problem is fixed.
We recommend routine diagnostic checks as per your car's manufacturer's recommendations or sooner if you experience any warning lights, unusual noises, or changes in performance.
Ignoring underlying issues can lead to more serious problems and costly repairs in the long run. Early diagnosis allows us to catch issues before they escalate.
We offer competitively priced diagnostic services, and the investment often pales in comparison to the cost of potential repairs if problems are left unchecked.
