Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.
Allow the engine to cool before inspecting any components.

2. Resolve Check Engine Light Issue

Sub-steps:
1. Use the OBD-II scanner to identify the specific error codes triggering the check engine light.
2. Address the identified issue based on the error code (e.g., replace faulty sensors, fix vacuum leaks).
3. Clear the error codes using the scanner.

3. Address ABS Warning Light

Sub-steps:
1. Inspect ABS sensors on each wheel for damage or disconnection.
2. Replace any faulty ABS sensors as needed.
3. Inspect the ABS module wiring for faults and repair if necessary.

4. Fix Battery Warning Light

Sub-steps:
1. Test the battery with a multimeter to ensure it is holding charge (should read around 12.6 volts with the engine off).
2. If the battery is weak, replace it with a new one.
3. Check the alternator output; it should be between 13.7 to 14.7 volts with the engine running. Replace if necessary.

5. Resolve Low Oil Pressure Light

Sub-steps:
1. Check the oil level with the dipstick; top off or change the oil if low.
2. Inspect the oil pressure sending unit for leaks or damage, replacing if faulty.
3. If oil levels are fine, use a mechanical gauge to test oil pressure.
