Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Error Codes

Reconnect the OBD-II scanner and note down all error codes.
Research each error code to determine the affected systems.
Clear the error codes after repairs to reset the warning lights.

3. Battery Inspection and Replacement

Reconnect the battery terminals and check voltage with a multimeter.
If the battery voltage is low (below 12.4 volts), replace the battery.
- Use a socket set to remove the battery terminals (negative first, then positive).
- Remove the battery hold-down bracket and lift out the old battery.
- Install the new battery, securing it in place and reconnecting terminals (positive first, then negative).

4. Brake System Inspection

Check the brake fluid reservoir for proper fluid level.
If low, add recommended brake fluid (DOT 3 or DOT 4).
Inspect brake lines for leaks or damage and replace any faulty components.

5. Tire Pressure and Stability Control

Check and inflate tires to the manufacturer-recommended pressure.
If stability control light persists, inspect wheel speed sensors for damage or debris.
Clean or replace any damaged sensors as needed.
