Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during the inspection.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and record any diagnostic trouble codes (DTCs) displayed.

3. Inspect Battery and Connections

Use a multimeter to check the battery voltage (should be around 12.6 volts).
Clean any corrosion from battery terminals and ensure tight connections.
If the battery is weak, replace it with a new one.

4. Check Engine Oil Level

Remove the dipstick and wipe it clean, then reinsert it and remove it again to check the oil level.
If low, add the appropriate type and grade of engine oil as specified in the owner’s manual.

5. Inspect Brake Fluid and ABS System

Check the brake fluid reservoir for low fluid levels, and refill if necessary.
Inspect the ABS sensors on the wheels for damage or dirt, clean if needed.

6. Verify Tire Pressure and ABS Functionality

Check all tire pressures and inflate them to the recommended PSI.
Test the ABS system by taking the vehicle for a short drive and monitoring the ABS warning light.
