Guided Project: Diagnosing the Injection Light

1. Connect your OBD-II dongle to the port under the steering wheel and pair with your favorite app (Torque Pro, Car Scanner or FIXD).
2. Open the “Fault Codes” section in the app: wait a few seconds while it reads the PCM (engine control module).
3. Write down the DTC code which appears, for example P0301 (misfire in cylinder 1).
4. Interpret the error: Use the built-in database to find out if it's a spark plug, coil, or low compression.
5. Solve it in a simple way: Check oil level and quality, tighten or replace the affected spark plug/coil pack.
6. Delete the code from the app and turn off the engine.
7. Take a driving test 10–15 minutes: Check that the light does not reappear and that the motor responds smoothly.

With this mini project, you'll go from being puzzled by a fault light to knowing how to identify and correct the most common cause in less than 30 minutes.

Customizing dashboards and alerts

To get the most out of it, adapt your digital board:

• Configure key gauges: In Torque Pro, add RPM, coolant temperature, and fuel pressure gauges; in Car Scanner, choose parameters for lambda and EGR sensors.
• Create multiple screens: separates “city monitor” (temperature, instantaneous consumption) from “route monitor” (speed, acceleration).
• Adjust colors and positions: Highlights high temperature or low pressure alerts in red.
• Activate push notifications: With FIXD, you receive automatic notifications when a problem is detected or a maintenance due date arrives.
• Save templates: Export your dashboards as screenshots or configuration files to share with friends or restore them on another device.

This way, your phone becomes a professional dashboard that alerts you instantly and visually guides you through any anomalies.

Predictive maintenance with apps

The key is to anticipate the breakdown:

• Schedule reminders: In FIXD, create tasks for oil changes (every 10,000 km), air filters (every 20,000 km), and brake checks (annually).
• Record each review: Record the date, mileage, and changed parts in the Car Scanner maintenance section or in Torque Pro notes.
• Monitor engine hours: For off-road work, use apps that calculate travel time and provide hourly alerts.
• Share reports: Export mileage and fault logs and send them to your trusted workshop for further analysis.
• Take advantage of temperature and voltage alerts: Anticipate overheating or weak battery problems before a long trip.

With a predictive routine, you minimize the risk of downtime and optimize the lifespan of each component.

Care and safety when getting into the car

Before any intervention, prioritize your protection:

• Ventilated space: works in an open garage or with air extraction.
• Insulated tools: Use rubber-handled wrenches and bits to avoid short circuits.
• Ergonomic posture: Keeps your back straight and prevents sudden twisting when bending under the hood.
• Battery disconnection: If you are going to touch circuits, disconnect the negative terminal to prevent shocks.
• Gloves and glasses: Protect your hands from hot oils and your eyes from particles or sparks when loosening screws.
• Adequate lighting: Use a headlamp to keep your hands free and allow good visibility in dark corners.

These precautions ensure that your training doesn't compromise your integrity and makes every repair a safe experience.
