Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, basic socket set, multimeter, and safety gloves.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Address Engine Light

Sub-step 1: Connect the OBD-II scanner to the vehicle’s diagnostic port.
Sub-step 2: Record any trouble codes and research their meanings.
Sub-step 3: Clear the codes and take the vehicle for a test drive to see if they reappear.
Sub-step 4: If codes return, follow the specific troubleshooting steps related to the identified issue.

3. Inspect Fluid Levels

Sub-step 1: Open the hood and check engine oil level using the dipstick; add oil if necessary.
Sub-step 2: Inspect coolant reservoir and top off if low.
Sub-step 3: Check brake fluid reservoir and add fluid if necessary.

4. Inspect Battery and Charging System

Sub-step 1: Use a multimeter to check battery voltage; a healthy battery should read between 12.4V and 12.7V.
Sub-step 2: Inspect battery terminals for corrosion and clean if necessary.
Sub-step 3: Test the alternator output to ensure it is charging the battery properly (should be between 13.5V and 14.5V when the engine is running).

5. Brake System and ABS Check

Sub-step 1: Visually inspect the brake pads and rotors for wear.
Sub-step 2: Check the ABS wheel speed sensors for dirt or damage.
Sub-step 3: If necessary, replace any damaged sensors and reset the ABS light as per the manufacturer’s manual.
