Disconnect the negative terminal of the battery before performing any electrical checks.
Ensure the vehicle is in park (automatic) or neutral (manual) for safety.

2. Battery Inspection

Sub-steps:
1. Use a multimeter to measure the battery voltage. If it is below 12.4 volts, proceed to charging or replacing the battery.
2. Clean any corrosion from the battery terminals using a battery terminal cleaner.
3. Tighten any loose connections at the battery terminals.

3. Starter Relay and Fuses Check

Sub-steps:
1. Locate the fuse box and identify the starter relay.
2. Remove the starter relay and swap it with a similar one to test functionality.
3. Inspect the fuse associated with the starting system. Replace any blown fuses with the correct amperage.
