Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is in a safe, flat location.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-step 1: Remove the battery cover (if applicable) by unscrewing any fasteners.
Sub-step 2: Disconnect the positive terminal first, followed by the negative terminal.
Sub-step 3: Remove the battery from the vehicle and test it with a multimeter. If it's below 12.4 volts, charge or replace it.
Sub-step 4: Clean the battery terminals and cable ends with a wire brush.
Sub-step 5: Reinstall the new or charged battery, connecting the positive terminal first and then the negative terminal.

3. Starter Relay and Fuse Check

Sub-step 1: Locate the starter relay in the fuse box (refer to the owner's manual for location).
Sub-step 2: Remove the relay and inspect for any visible damage.
Sub-step 3: Swap the starter relay with another identical relay to test functionality.
Sub-step 4: Check the starter fuse in the fuse box for continuity; replace if blown.

4. Starter Motor Inspection

Sub-step 1: If the issue persists, locate the starter motor (refer to the service manual for location).
Sub-step 2: Inspect wiring and connections for damage or looseness.
Sub-step 3: Use a multimeter to check for voltage at the starter motor terminal when the ignition is engaged.
Sub-step 4: If no voltage is present, the starter motor may need replacement.
