1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal.
2. Inspect the battery for any swelling, corrosion, or leaks.
3. If the battery is faulty, replace it with a new battery of the same specifications (usually 12V, Group size as per manufacturer’s recommendation).
4. Clean the battery terminals with a wire brush and a mixture of baking soda and water.
5. Reconnect the battery terminals, ensuring they are tight.

3. Starter Motor Check

Sub-steps:
1. Access the starter motor (usually located near the transmission).
2. Disconnect the wiring harness from the starter motor.
3. Check for any signs of damage or corrosion on the connectors.
4. Using a multimeter, test the starter motor for continuity.
5. If the motor is faulty, replace it with a new starter motor.
6. Reconnect the wiring harness and ensure all connections are secure.

4. Ignition Switch and Relay Inspection

Sub-steps:
1. Locate the ignition switch and visually inspect for wear or damage.
2. Test the ignition switch for continuity with a multimeter.
3. If defective, replace the ignition switch.
4. Check the starter relay by swapping it with a similar relay in the fuse box as a test.
5. Replace the starter relay if it does not function properly.
