Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Addressing Error Codes

Sub-step 1: Connect the OBD-II scanner to the vehicle's diagnostic port.
Sub-step 2: Record all error codes and refer to the service manual for descriptions.
Sub-step 3: Clear the error codes and perform a test drive to see if any lights reappear.

3. Fluid Level Checks

Sub-step 1: Check engine oil level using the dipstick; add oil if necessary.
Sub-step 2: Inspect coolant level in the reservoir; top up if low with the appropriate coolant type.
Sub-step 3: Examine brake fluid reservoir; fill with the recommended brake fluid type if needed.

4. Battery and Alternator Inspection

Sub-step 1: Use a multimeter to measure the battery voltage; it should be between 12.4V and 12.7V when the engine is off.
Sub-step 2: Start the engine and measure the voltage again; it should be between 13.7V and 14.7V, indicating proper alternator function.
Sub-step 3: If readings are out of range, replace the battery or alternator as necessary.

5. Brake System Inspection

Sub-step 1: Remove the wheel to access the brake components.
Sub-step 2: Inspect brake pads for wear; replace if thickness is below the manufacturer’s specifications.
Sub-step 3: Check brake lines for leaks or damage; replace any compromised lines.

6. Wiring and Component Inspection

Sub-step 1: Visually inspect all wiring harnesses connected to the engine and braking systems for frays or disconnections.
Sub-step 2: Repair or replace any damaged wiring as necessary.
Sub-step 3: Ensure all connectors are seated properly to prevent further electrical issues.
