Solution

1. Preparation

Gather tools: Socket set, multimeter, OBD-II scanner, wrench set.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery cable to prevent electrical shorts.

2. Inspect Battery Connections

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean any corrosion from terminals and cable ends using a wire brush.
3. Reconnect the terminals securely, ensuring a tight fit.

3. Check and Replace Fuses

Sub-steps:
1. Locate the fuse box and remove the cover.
2. Inspect fuses related to the starting system (refer to the fuse diagram).
3. Replace any blown fuses with new ones of the same amperage.

4. Test the Starter Motor

Sub-steps:
1. Reconnect the negative battery cable.
2. Use a multimeter to measure voltage at the starter motor terminal while a helper turns the key to the start position.
3. If voltage is present but the starter does not engage, replace the starter motor.

5. Inspect the Ignition Switch

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Use a multimeter to test for continuity across the ignition switch terminals when turned to the start position.
3. If there is no continuity, replace the ignition switch.
