Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Addressing Check Engine Light

Use the OBD-II scanner to clear the error codes after repairs are made.
If codes persist, investigate specific components associated with the identified codes (e.g., oxygen sensors, catalytic converter).
Replace any faulty components as necessary.

3. Resolving ABS Warning Light

Inspect the ABS wheel speed sensors at each wheel for dirt or damage.
Clean any debris from the sensors and connectors.
Replace faulty sensors if necessary.

4. Correcting Tire Pressure Warning Light

Adjust tire pressures to the recommended levels as stated on the driver’s door jamb.
Reset the tire pressure monitoring system (TPMS) according to the manufacturer’s instructions.
Replace any defective TPMS sensors if the warning light remains on.

5. Stabilizing Stability Control System

Inspect the stability control system for fault codes using the OBD-II scanner.
Repair or replace any components indicated by the fault codes.
Clear codes and test the system to ensure proper function.
