Ensure the vehicle is in PARK and the parking brake is engaged. Disconnect the negative battery terminal to prevent any electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Use a multimeter to confirm the battery voltage. If below 12.4 volts, proceed to jump-start the vehicle.
2. If the battery is unable to hold a charge, replace it with a new battery of the same specifications.
3. Clean the battery terminals with a wire brush and ensure a tight connection before reconnecting.

3. Starter Motor Testing and Replacement

Sub-steps:
1. Locate the starter motor under the vehicle (consult the service manual for exact location).
2. Disconnect the wiring harness from the starter motor.
3. Use a multimeter to test the starter motor by applying direct voltage from the battery. If it does not engage, it requires replacement.
4. Remove the starter motor using the appropriate socket size (typically 10mm or 12mm).
5. Install the new starter motor and reconnect the wiring harness.

4. Final Checks

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the vehicle to verify that the issue is resolved.
