Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery negative terminal to avoid electrical shorts.

2. Resolve Check Engine Light

Sub-steps:
1. Connect the OBD-II scanner to the vehicle's diagnostic port.
2. Record any error codes and research them to identify the specific issue.
3. Clear the codes and start the engine to see if the light returns.
4. If the light reappears, address the specific issue based on the error code (e.g., replace faulty sensors).

3. Address ABS and Traction Control Lights

Sub-steps:
1. Inspect ABS wheel speed sensors for dirt, damage, or wiring issues.
2. Clean or replace any faulty sensors or connectors.
3. If necessary, bleed the brake system to ensure proper hydraulic function.

4. Fix Oil Pressure Warning

Sub-steps:
1. Check engine oil level and condition.
2. If low, top up with the appropriate oil type (refer to owner’s manual).
3. If levels are adequate, test the oil pressure sending unit with a multimeter.
4. Replace the sending unit if it’s defective.

5. Resolve Battery Warning Light

Sub-steps:
1. Use a multimeter to check the battery voltage (should be around 12.6V).
2. Inspect battery connections for corrosion or looseness.
3. If the battery is weak, replace it with one that meets OEM specifications.
4. Test the alternator output to ensure it is charging correctly (should be around 13.7V to 14.7V when running).
