Solution

1. Preparation

Gather tools: multimeter, wrench set, OBD-II scanner, remote starter switch.
Ensure the vehicle is in a safe location and the parking brake is engaged.

2. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative terminal of the battery using a wrench (safety: wear gloves and goggles).
2. Inspect battery terminals for corrosion; clean with a wire brush if necessary.
3. Reconnect the terminals and check voltage again with the multimeter.
4. If the battery is below 12.4 volts, charge the battery or replace it if it’s unable to hold a charge.
5. If replacing, remove the old battery by undoing the positive terminal first, then the negative, and install the new battery in reverse order.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor and inspect the connections (ensure the vehicle is in "Park").
2. Use the remote starter switch to connect directly to the starter motor terminal to see if it engages (if it clicks, the starter may be faulty).
3. If the starter engages, proceed to test the ignition switch and associated wiring.

4. Fuse Inspection

Sub-steps:
1. Locate the fuse box and identify the starter relay and ignition fuses.
2. Remove and inspect the fuses; replace any that are blown with fuses of the same amperage.
3. Reassemble the fuse box and attempt to start the vehicle.
