Follow the scanner's instructions to read and record the trouble codes.

3. Interpret the Codes

Cross-reference the retrieved codes with the manufacturer's specifications or an online database to determine the specific issue indicated by the warning light.
Note any recommended repairs or common issues associated with the codes.

4. Address Identified Issues

Based on the trouble codes, perform necessary repairs, such as replacing faulty sensors, topping off fluids, or addressing any mechanical issues identified.
