Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather necessary tools and parts.
Disconnect the battery to avoid electrical shorts during repairs.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record all error codes and clear them from the system.
If the check engine light reactivates, focus on the specific code indicated.

3. Fluid Level Check

Open the hood and check engine oil, coolant, and brake fluid levels.
Top off any low fluids using manufacturer-recommended types.
Inspect for leaks that may cause fluid loss and repair as necessary.

4. Battery Inspection

Inspect battery terminals for corrosion and clean if necessary using a wire brush.
Check battery voltage with a multimeter; it should read between 12.4V and 12.7V when fully charged.
Replace the battery if voltage is below 12.4V.

5. Brake System Inspection

Inspect brake fluid reservoir for proper fluid level.
Check brake lines and hoses for leaks or damage.
Replace any damaged components or top off brake fluid as needed.

6. ABS and Traction Control Reset

Use an appropriate diagnostic tool to check ABS system status.
If any faults are found, replace defective ABS sensors or modules.
Clear the ABS fault codes and test the system.
