Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, and a battery terminal cleaner.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Inspect the Battery:
1. Remove the battery cover if applicable.
2. Clean the battery terminals using a terminal cleaner to remove any corrosion.
3. Tighten the battery terminals to ensure a good connection.
4. Reconnect the negative battery terminal.

3. Battery Testing

Test Battery Voltage:
1. Reconnect the battery and use a multimeter to measure the voltage.
2. If the voltage is below 12.4 volts, proceed to replace the battery.
3. If the battery is good, move on to testing other components.

4. Starter Relay Check

Replace the Starter Relay:
1. Locate the starter relay in the fuse box.
2. Remove the relay and inspect for damage.
3. Replace with a known good relay if necessary.

5. Starter Motor Inspection

Inspect the Starter Motor:
1. Locate the starter motor under the vehicle.
2. Check the wiring harness for damage or loose connections.
3. If accessible, test the starter motor by applying direct battery voltage to it using jumper cables. If it does not engage, it may need replacement.
