Solution

1. Preparation

Gather tools: multimeter, socket set, torque wrench, OBD-II scanner, and safety gloves.
Ensure the vehicle is in park (or neutral for manual transmission) and the parking brake is engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative (-) battery terminal using a wrench.
Sub-step 2: Clean any corrosion from the battery terminals and the cable connectors using a wire brush.
Sub-step 3: Reconnect the terminals securely, ensuring a tight fit.

3. Starter Relay and Fuse Check

Sub-step 1: Locate the fuse box (usually under the dashboard or in the engine compartment).
Sub-step 2: Inspect the starter relay; if necessary, swap it with a similar relay to test functionality.
Sub-step 3: Check the fuses related to the starting system (refer to the owner’s manual for their location) and replace any that are blown.

4. Starter Motor Inspection

Sub-step 1: If the above steps do not resolve the issue, access the starter motor (may require removing components for clearance).
Sub-step 2: Inspect the wires connecting to the starter for any frays or loose connections.
Sub-step 3: Check the starter motor operation by applying direct power from the battery; if it does not engage, it may need replacement.

5. Final Assembly

Sub-step 1: Reassemble any components removed to access the starter motor.
Sub-step 2: Reconnect the negative battery terminal.
Sub-step 3: Ensure all tools and materials are removed from the engine bay.
