Solution

1. Preparation

Tools Required: Multimeter, socket set, wrench set, OBD-II scanner.
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
- Disconnect the negative terminal of the battery to ensure safety.
- Clean any corrosion from the terminals using a wire brush.
- Reconnect the battery terminals securely.
- If the battery voltage is below 12.4 volts, jump-start the vehicle or replace the battery.

3. Starter Relay Inspection

Sub-steps:
- Locate the starter relay in the fuse box (refer to the owner’s manual for location).
- Remove the relay and visually inspect it for damage.
- Swap it with a similar relay to test functionality.
- If the vehicle starts, replace the faulty relay.

4. Starter Circuit Testing

Sub-steps:
- Reconnect the battery.
- Use a multimeter to perform a voltage drop test on the starter circuit while attempting to start the engine.
- If voltage drop exceeds 0.2 volts, inspect wiring for damage or loose connections.

5. Starter Replacement (if necessary)

Sub-steps:
- Disconnect the negative battery terminal.
- Remove any components obstructing access to the starter.
- Unbolt the starter from the engine block and disconnect the electrical connectors.
- Install the new starter by reversing the removal process and ensuring all connections are secure.
- Reconnect the negative battery terminal.
