Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, jumper wires.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection

Sub-steps:
1. Reconnect the battery terminals and check for tightness.
2. Clean any corrosion from the battery terminals using a mixture of baking soda and water.
3. Retest the battery voltage with a multimeter; if below 12.4 volts, charge the battery or replace it if necessary.

3. Starter Motor Diagnosis

Sub-steps:
1. Locate the starter motor under the vehicle.
2. Disconnect the starter wiring harness and the main power cable from the starter.
3. Use jumper wires to directly connect the starter motor to the battery to see if it engages.
4. If the starter does not engage, replace the starter motor; if it does engage, continue to the next step.

4. Ignition Switch and Fuses

Sub-steps:
1. Remove the ignition switch cover and check for any damaged wires or loose connections.
2. Test the ignition switch for continuity in the start position using a multimeter.
3. Replace any blown fuses related to the starter circuit found in the fuse box.

5. Ground and Electrical Connections

Sub-steps:
1. Inspect the ground connections on the engine block and chassis for corrosion or looseness.
2. Clean and tighten any loose connections.
3. Reconnect the negative battery terminal and test the ignition again.
