Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, battery terminal cleaner.
Disconnect the negative battery terminal to prevent any electrical shorts during repairs.

2. Battery Inspection

Check battery connections for tightness and clean any corrosion with a battery terminal cleaner.
If the battery voltage is low (below 12.4 volts), charge the battery or replace it if it fails to hold a charge.

3. Starter Relay and Fuse Check

Remove the starter relay from the fuse box and inspect for damage. If necessary, replace it with a new relay.
Check the fuses associated with the starter circuit and replace any that are blown.

4. Starter Motor Inspection

If the starter relay and fuses are functional, proceed to check the starter motor.
Locate the starter motor, disconnect the wiring harness, and use a multimeter to check for voltage at the starter terminal when the key is turned to "START." If there is voltage and the starter does not engage, replace the starter motor.

5. Reconnect and Test

Reconnect the battery terminal.
Start the vehicle to verify that the issue is resolved.
