Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, cleaning supplies (wire brush, contact cleaner).
Ensure the vehicle is in park (P) and the parking brake is engaged.
Disconnect the battery to prevent any electrical short or shock while working.

2. Battery Inspection and Replacement

Check battery voltage:
- Set the multimeter to DC voltage.
- Connect the probes to the battery terminals (red to positive, black to negative).
- Read the voltage; if it’s below 12.4 volts, proceed to replace the battery.
Clean battery terminals:
- Remove the battery cables (negative first, then positive).
- Use a wire brush and contact cleaner to clean the terminals and cable ends.
- Reconnect the battery cables securely (positive first, then negative).
Replace the battery (if necessary):
- Remove the battery hold-down bracket.
- Lift the old battery out and place the new battery in the same orientation.
- Reattach the hold-down bracket and terminals.

3. Starter Relay Inspection

Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
Remove the starter relay using a socket set.
Test the relay by swapping it with an identical relay in the fuse box.
Reinstall the relay or replace it if it was found faulty.

4. Starter Motor Check

Access the starter motor by removing any necessary components for clearance.
Inspect wiring for damage or loose connections.
Test the starter motor with a multimeter by checking for voltage at the starter terminal when attempting to start the vehicle.
If no voltage is present, further investigate the ignition switch and wiring.
