Solution

1. Preparation

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

2. Code Retrieval

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position (do not start the engine).
Follow the scanner instructions to read the stored error codes.
Document any codes for further analysis.

3. Inspect and Repair

Based on the retrieved codes, identify the component related to the warning light.
If a specific sensor is faulty, remove the sensor:
- Sub-steps:
  - Locate the sensor based on the vehicle service manual.
  - Disconnect the electrical connector.
  - Remove the mounting bolts (if applicable).
  - Install the new sensor and reconnect the electrical connector.
If a fluid level is low, top off the respective fluid (coolant, oil, etc.) with the correct fluid type.

4. Reset the Warning Light

Reconnect the battery terminal.
Use the OBD-II scanner to clear any stored codes and reset the warning light.
Start the engine and allow it to reach operating temperature to check for re-illumination of the warning light.
