Solution

1. Preparation

Gather tools and parts required for repairs.
Ensure the vehicle is parked on a flat surface, and the ignition is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Addressing Diagnostic Trouble Codes (DTC)

Sub-step 1: Connect the OBD-II scanner to the vehicle's diagnostic port and retrieve the error codes.
Sub-step 2: Research the codes to determine the specific issues. Refer to the vehicle's service manual for guidance.
Sub-step 3: Clear the codes using the OBD-II scanner and check if they reappear after taking corrective actions.

3. Fluid and Battery Inspection

Sub-step 1: Check and top off engine oil, coolant, and brake fluid levels as necessary. Replace fluids if they are dirty or contaminated.
Sub-step 2: Inspect the battery terminals for corrosion and ensure they are tightly connected. Clean the terminals if corrosion is present.
Sub-step 3: Use a multimeter to check battery voltage; it should read between 12.4V to 12.7V when the engine is off. If below this range, consider replacing the battery.

4. Fuse Inspection

Sub-step 1: Locate the fuse box (usually under the dashboard or in the engine compartment).
Sub-step 2: Check the fuses related to the illuminated warning lights; replace any blown fuses with the same amperage rating.

5. Brake System Check

Sub-step 1: Inspect the brake fluid level and ABS sensors for any damage or disconnection.
Sub-step 2: If the ABS warning light persists, consider using a scan tool to check for ABS-specific codes and follow the necessary diagnostic procedures.
