Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, socket set, jumper wires.
Ensure the vehicle is in park and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery.
2. Clean the terminals with a wire brush to remove any corrosion.
3. Reconnect the terminals securely and test the voltage again.
Tools Required: Multimeter, wire brush.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor under the vehicle.
2. Use jumper wires to bypass the starter solenoid: connect the positive terminal directly to the starter terminal and the negative to the body ground.
3. If the starter engages, it may need replacement; if not, further diagnosis is necessary.
Tools Required: Jumper wires, socket set.

4. Fuse Inspection

Sub-steps:
1. Locate the fuse box and refer to the owner's manual for the starting system fuse location.
2. Remove the suspected fuse and inspect it visually or use a multimeter to check continuity.
3. Replace any blown fuses with the same amperage rating.
Tools Required: Fuse puller or pliers.

5. Ignition Switch Examination

Sub-steps:
1. Access the ignition switch assembly.
2. Check for loose connections or damaged wiring.
3. If necessary, replace the ignition switch following the manufacturer’s instructions.
Tools Required: Screwdriver set, socket set.
