Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and safety gloves.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery to prevent electrical shorts.
2. Clean the battery terminals using a wire brush to remove any corrosion.
3. Reconnect the battery terminals tightly after cleaning.

3. Starter Motor Replacement

Sub-steps:
1. Disconnect the negative battery terminal again.
2. Locate the starter motor; it is typically found near the engine block.
3. Remove the wiring harness connected to the starter.
4. Unbolt the starter motor using the appropriate socket size (usually 10mm or 12mm).
5. Carefully remove the starter motor from its mount without damaging surrounding components.
6. Install the new starter motor in reverse order and torque bolts to manufacturer specifications (usually around 15-20 ft-lbs).

4. Relay and Ignition Switch Check

Sub-steps:
1. Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
2. Swap the starter relay with another identical one in the fuse box to test functionality.
3. If the problem persists, proceed to check the ignition switch by removing the steering column cover and testing for continuity using a multimeter.
