Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to reset the electronic systems.

2. Addressing Specific Warning Lights

A. Check Engine Light

Review the error codes retrieved from the OBD-II scanner.
Perform repairs based on the specific code (e.g., replace faulty sensors, fix leaks).
Clear the codes using the OBD-II scanner and reconnect the battery.

B. ABS Warning Light

Inspect ABS wheel speed sensors for damage or dirt buildup.
Clean or replace any malfunctioning sensors.
Check the ABS fuse and replace if blown.

C. TPMS Light

Verify tire pressures using a tire pressure gauge and inflate tires as necessary.
Reset the TPMS using the vehicle's reset button or through the OBD-II scanner.
If the light persists, inspect the TPMS sensors for faults or battery failures.

D. Maintenance Required Light

Check the vehicle's service history to determine overdue maintenance items.
Perform necessary services (e.g., oil change, filter replacements).
Reset the Maintenance Required light using the trip reset button.
