1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Clean the battery terminals using a wire brush.
2. If the battery voltage is below 12.4 volts, jump-start the vehicle or replace the battery.
3. Reconnect the battery terminals securely.

3. Starter Motor Access and Testing

Sub-steps:
1. Remove any covers obstructing access to the starter motor.
2. Disconnect the starter electrical connectors.
3. Check for voltage at the starter solenoid terminal when the ignition key is turned to the start position.
4. If no voltage is present, investigate wiring and ignition switch.
5. If voltage is present, replace the starter motor.

4. Ignition Switch Testing

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Disconnect the ignition switch connector.
3. Use a multimeter to check for continuity when the key is turned to the start position.
4. Replace the ignition switch if it fails continuity tests.
