Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety during inspections and repairs.

2. Inspect Battery and Charging System

Tools Required: Multimeter, wrench set
Use a multimeter to check the battery voltage (should be around 12.6 volts).
Inspect battery terminals for corrosion or loose connections. Clean and tighten as necessary.
Check the alternator output to ensure it is charging the battery properly (should be around 13.5-14.5 volts when the engine is running).

3. Check Fluid Levels

Tools Required: Funnel, measuring tools
Check engine oil level using the dipstick and add oil if low (use the recommended oil type).
Inspect brake fluid reservoir and add fluid if the level is below the minimum mark.

4. Inspect ABS and Traction Control Systems

Tools Required: OBD-II scanner, multimeter
Use the OBD-II scanner to check for ABS-related error codes and address any faults indicated.
Perform a visual inspection on wheel speed sensors for damage or disconnection.
Test the ABS module with a multimeter for continuity and proper electrical function.

5. Reconnect Battery

Reconnect the battery terminals, ensuring they are tight and free of corrosion.

6. Clear Error Codes

Use the OBD-II scanner to clear any stored trouble codes after repairs are made.
Conduct a short test drive to ensure warning lights do not reappear.
