Solution

1. Battery Inspection and Replacement

Sub-steps:
1. Turn off all electrical accessories and ensure the vehicle is in the "Off" position.
2. Disconnect the negative (-) battery terminal first, followed by the positive (+) terminal.
3. Clean any corrosion from the battery terminals using a wire brush and a mixture of baking soda and water.
4. Reconnect the battery terminals, ensuring they are tight and secure.
5. If the battery voltage is low (below 12.4 volts), replace the battery with a new one.

2. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor (typically near the transmission).
2. Disconnect the electrical connector and the battery cables from the starter.
3. Use a multimeter to test for voltage at the starter motor when the ignition is turned to "Start."
4. If there is voltage but the starter does not engage, replace the starter motor.
5. If no voltage is present, the issue may be with the ignition switch or starter relay.

3. Replace Starter Relay (if applicable)

Sub-steps:
1. Locate the fuse box and identify the starter relay.
2. Remove the faulty starter relay and replace it with a new one.
3. Recheck the starting system functionality.
