1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, jumper wire.
Ensure the vehicle is in a safe position with the ignition turned off.

2. Battery Replacement

Sub-steps:
1. Disconnect the negative terminal first, then the positive terminal from the battery.
2. Remove the old battery from the battery tray.
3. Clean the battery terminal connectors with a wire brush to remove corrosion.
4. Install the new battery by placing it in the tray and connecting the positive terminal first, then the negative terminal.
5. Tighten the terminals securely but avoid overtightening.

3. Starter Replacement (if necessary)

Sub-steps:
1. Disconnect the negative battery terminal.
2. Locate the starter motor, typically mounted near the transmission housing.
3. Remove the electrical connections from the starter (note their positions).
4. Unbolt the starter motor from its mounting (usually 2-3 bolts).
5. Install the new starter motor by reversing the removal steps, ensuring all connections are secure.

4. Ignition Switch Inspection/Replacement

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
