Solution

1. Preparation

Gather tools: multimeter, socket set, jump wire, OBD-II scanner.
Ensure the vehicle is in park (automatic) or neutral (manual) and set the parking brake.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery Inspection

Sub-step 1: Clean battery terminals using a wire brush to remove any corrosion.
Sub-step 2: Tighten the battery terminals securely; ensure a good connection.
Sub-step 3: If the battery voltage is below 12.4 volts, jump-start the vehicle or replace the battery if it fails to hold a charge.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor, typically found near the transmission.
Sub-step 2: Using a jump wire, connect the battery positive terminal directly to the starter motor's terminal to check if it engages.
Sub-step 3: If the starter engages, the issue may be with the ignition switch or wiring; if it does not engage, replace the starter motor.

4. Fuses and Wiring Inspection

Sub-step 1: Locate the fuse box in the engine compartment and check for any blown fuses related to the starting system.
Sub-step 2: Replace any blown fuses with the correct amperage rating.
Sub-step 3: Inspect the wiring harness for any signs of damage or loose connections.

5. Reassemble and Connect

Sub-step 1: Reconnect the negative battery terminal securely.
Sub-step 2: Ensure all tools are removed from the engine bay and close the hood.
