Step 3: Start the engine and monitor if the warning light reappears.

3. Check Oil Pressure Warning

Step 1: If the oil warning light is on, check and top off oil if necessary.
- Use the correct oil type as specified in the owner's manual.
Step 2: If the light persists, inspect the oil pressure sending unit for faults.
Step 3: Replace the oil pressure sending unit if defective.

4. Resolve ABS or Transmission Warning Light

Step 1: Inspect the ABS sensor at each wheel for damage or disconnection.
Step 2: Check the transmission fluid level and condition; replace if low or burnt.
