Diagnostic Auto-Electrics

Fault diagnosis, investigatory diagnosis, Engine Control Unit (ECU), Engine Control Module (ECM), Body Control Module (BCM) checks and much more.

What is Diagnostics?

On‑Board Diagnostics (OBD/OBD‑II): A standard computer system built into modern vehicles (mandatory in the UK/EU since around 2001–2004) that continually monitors components like the engine, transmission, brakes, emissions, airbags, and more.

Diagnostic Tool: A handheld scanner or tablet plugged into the OBD port retrieves Diagnostic Trouble Codes (DTCs) and live sensor data.

How it Works

  1. Vehicle sensors detect anomalies and set fault codes

  2. The diagnostic tool reads these codes and often explains them

  3. Live data from sensors (like engine temperature or oxygen levels) helps mechanics dive deeper

Why it Matters

  • Fault Detection Accuracy: Eliminates guesswork – pinpoints issues in engine, ABS, airbags, emissions, electrical systems and more

  • Early Detection and Savings: Finds minor problems before they become expensive repairs – e.g., a simple injector fix vs. complete engine work

  • Performance and Efficiency: Fixing sensor errors can restore fuel economy and smooth running

  • Safety Assurances: Verifies critical systems like brakes, airbags, stability control, lighting, etc. are working properly

  • Regulatory Compliance: Ensures emissions systems meet standards for MOT and environmental protection

  • Longevity and Resale Value: Regular diagnostic checks extend vehicle life and support resale, showing documented maintenance

What Tools Can Do

  • Basic Code Readers: Show error codes and let you clear warning lights

  • Advanced Scanners: Offer live data, freeze-frame reads, component-specific diagnostics

  • OEM-Level Tools: Access manufacturer-specific modules (transmission, ABS, airbags)

When the “check engine” light appears, it’s a generic alert. Only a diagnostic scan shows exactly what’s wrong – whether it’s a loose fuel cap or a failing catalytic converter.

Regular Scanning: A Smart Routine

Even with no warning lights, occasional diagnostic scans can uncover hidden faults early – keeping your car safe, well-running, and cheaper to maintain.
