Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely parked.
Disconnect the battery before starting work, especially if addressing electrical issues.

2. Address Engine Warning Light

Sub-step 1: Identify the error codes from the OBD-II scanner.
Sub-step 2: Research the error codes to determine the necessary repairs (e.g., replace sensors, repair wiring).
Sub-step 3: Perform the required repairs or component replacements based on the diagnostic results.

3. Address ABS and Traction Control Lights

Sub-step 1: Check the ABS module and the wheel speed sensors for faults.
Sub-step 2: Clean or replace any faulty sensors.
Sub-step 3: Reconnect all wiring and clear the error codes using the OBD-II scanner.

4. Check Battery and Alternator

Sub-step 1: Use a multimeter to check the battery voltage; it should be around 12.6 volts when fully charged.
Sub-step 2: If voltage is low, charge the battery or replace it if necessary.
Sub-step 3: Inspect the alternator output; it should be between 13.7 to 14.7 volts when the engine is running.

5. Inspect and Change Oil
