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 ensure safety.
2. Scanning and Error Code Review
  • Tools Required: OBD-II scanner
  • Connect the OBD-II scanner to the vehicle’s diagnostic port.
  • Turn the ignition to the "ON" position without starting the engine.
  • Retrieve and record the error codes displayed on the scanner.
  • Cross-reference error codes with the vehicle service manual to identify the issue.
3. Fluid Inspection and Replacement
  • Tools Required: Fluid containers, funnel, socket set
  • Check and top off engine oil, coolant, and transmission fluid as needed.
  • If any fluid is low, inspect for leaks and replace as necessary.
  • Dispose of used fluids according to local regulations.
4. Battery Check and Replacement
  • Tools Required: Multimeter, socket set
  • Use a multimeter to check the battery voltage; it should read approximately 12.6 volts when fully charged.
  • If the voltage is low, clean battery terminals and connections.
  • If the battery is failing (voltage below 12.4 volts), replace it with a new one.
5. Engine Air Filter Replacement
  • Tools Required: Screwdriver or socket set (as applicable)
  • Locate the engine air filter housing and remove the retaining clips or screws.
  • Carefully remove the old air filter and inspect the housing for debris.
  • Install the new air filter, ensuring it is properly seated, and re-secure the housing.
6. Reconnect Battery and Clear Codes
  • Reconnect the negative battery terminal.
  • Use the OBD-II scanner to clear the error codes from the system.
  • Start the engine to check if the warning light has turned off.
