Solution

1. Preparation

Gather tools including a multimeter, socket set, and wrenches.
Ensure the vehicle is in a safe location and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery to prevent any electrical shorts.
2. Clean the battery terminals with a wire brush to remove any corrosion.
3. Reconnect the battery terminals securely.

3. Testing the Battery

Sub-steps:
1. Use a multimeter to measure the battery voltage; it should read between 12.4 to 12.6 volts.
2. If the voltage is low, consider jump-starting the vehicle or replacing the battery.

4. Starter Motor Check

Sub-steps:
1. Locate the starter motor, typically near the engine block.
2. Disconnect the starter wiring harness.
3. Use a multimeter to check for voltage at the starter terminal when the ignition is turned.
4. If there is no voltage, check the ignition switch and wiring for faults.
