Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify specific fault codes.
2
Check fluid levels, including engine oil, coolant, and transmission fluid.
3
Inspect the gas cap for tightness or damage, as a loose cap can trigger the check engine light.
4
Visually inspect engine components for wear, corrosion, or loose connections.
5
Test the battery and alternator output to ensure proper electrical supply.
6
Check the condition of spark plugs and ignition coils if misfiring is suspected.

Solution
