Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrench set, battery terminal cleaner, and a load tester.
Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.

2. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative battery terminal first, followed by the positive terminal.
2. Clean any corrosion on the terminals with a battery terminal cleaner.
3. Reconnect the battery terminals securely.
4. If the battery is found to be faulty, remove the old battery using a socket set (typically a 10mm socket).
5. Install a new battery, ensuring the positive (+) terminal is connected first, followed by the negative (-) terminal.

3. Starter Motor Inspection and Replacement

Sub-steps:
1. Locate the starter motor (usually near the transmission).
2. Disconnect the wiring harness from the starter motor.
3. Remove the mounting bolts using a socket set (typically 13mm).
4. Carefully remove the starter motor from its housing.
5. Install a new starter motor by reversing the disassembly steps and ensuring all connections are tight.

4. Testing the Electrical System

Sub-steps:
1. Reconnect the battery and ensure all connections are secure.
2. Use the OBD-II scanner to clear any previous error codes and check for new codes after repairs.
3. Attempt to start the engine to verify functionality.
