Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition key to the "ON" position without starting the engine.
Retrieve stored error codes and note any that are present.

3. Battery and Alternator Check

Reconnect the battery and start the engine.
Use a multimeter to measure the voltage at the battery terminals; it should read between 13.7V and 14.7V.
If the voltage is outside this range, replace the alternator or battery as needed.

4. Fluid Level Inspection

Check engine oil level using the dipstick and add oil if necessary.
Inspect the coolant reservoir and top off with the recommended coolant type.
Examine the brake fluid level and refill with DOT-approved brake fluid.

5. Fuse and Relay Inspection

Locate the fuse box, usually under the dashboard or engine compartment.
Use a fuse puller to check each fuse and replace any that are blown.
Inspect relays for proper operation and replace any faulty relays.

6. Wiring and Connector Inspection

Visually inspect wiring harnesses for fraying, exposed wires, or corrosion.
Disconnect and reconnect any connectors to ensure a good connection.
Repair or replace any damaged wiring or connectors.
