Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Addressing Check Engine Light

Use the OBD-II scanner to read the fault codes.
Based on the codes, inspect and replace faulty components (e.g., oxygen sensors, mass airflow sensor).
Clear the error codes and reconnect the battery.

3. Fixing ABS Warning Light

Inspect wheel speed sensors for dirt or damage and clean or replace as needed.
Check the ABS module for faults and replace if necessary.
After repairs, use the scanner to reset the ABS warning light.

4. Resolving Oil Pressure Warning Light

Check the oil level and condition; change oil and filter if needed.
Inspect the oil pressure sending unit for malfunction and replace if faulty.
Test the oil pressure using a mechanical gauge to confirm proper levels.

5. Addressing TPMS Light

Check all tire pressures and inflate as needed to manufacturer specifications.
If the light remains, perform a TPMS reset using the vehicle's onboard system or a TPMS tool.
Replace any faulty tire pressure sensors if necessary.

6. Fixing Traction Control Light

Inspect wheel speed sensors and stability control system for faults.
Clear any fault codes related to the traction control system.
Test drive the vehicle to confirm the traction control light does not reappear.
