Solution

1. Preparation

Tools Required: Multimeter, socket set, OBD-II scanner, torque wrench, wire brush, battery terminal cleaner.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the positive (+) battery terminal using a socket wrench.
2. Clean the battery terminals with a wire brush to remove any corrosion.
3. Reconnect the positive terminal securely.
4. If the battery voltage is low, replace it with a new battery of the same specifications.

3. Starter Motor and Ignition Switch Check

Sub-steps:
1. Locate the starter motor; it is usually situated near the transmission.
2. Disconnect the electrical connector from the starter motor.
3. Use a multimeter to check for voltage at the starter terminal when the ignition is turned to the start position.
4. If voltage is present, replace the starter motor.
5. If no voltage is detected, check the ignition switch wiring for faults and replace the ignition switch if necessary.

4. Fuse Inspection and Replacement

Sub-steps:
1. Locate the fuse box, typically found under the dashboard or in the engine compartment.
2. Identify the starter and ignition fuses using the diagram on the fuse box cover.
3. Remove the fuses using a fuse puller or pliers and inspect them for damage.
4. Replace any blown fuses with new ones of the appropriate amperage.
