Solution

1. Preparation

Tools Required: Multimeter, socket set, OBD-II scanner, wire brush, wrenches.
Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock or damage.

2. Inspect and Clean Battery Connections

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean the terminals and cable ends with a wire brush to remove any corrosion.
3. Reconnect the battery terminals securely (positive first, then negative).

3. Test and Replace the Battery (if necessary)

Sub-steps:
1. Reconnect the battery and check the voltage with a multimeter again.
2. If the voltage is low, charge the battery fully using an appropriate battery charger.
3. If the battery fails to hold a charge, replace it with a new one of the same specifications.

4. Inspect Starter Motor

Sub-steps:
1. Locate the starter motor, usually situated near the engine block.
2. Check the electrical connections to the starter for tightness and corrosion.
3. If necessary, test the starter by applying direct power; replace it if it does not engage.

5. Verify Ignition Switch and Fuses

Sub-steps:
1. Inspect the ignition fuse in the fuse box; replace it if blown.
2. Test the ignition switch for proper operation; replace if faulty.
