Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, jumper wires
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery to prevent any electrical shorts.
2. Clean any corrosion from the battery terminals with a wire brush.
3. Reconnect the terminals securely and check the connections for tightness.

3. Testing the Starter Motor

Sub-steps:
1. Locate the starter motor, typically found near the bottom of the engine near the transmission.
2. Disconnect the wiring harness from the starter motor.
3. Using jumper wires, connect the battery directly to the starter motor terminals to test its function.
4. If the starter engages and the engine cranks, the starter may be faulty; replace it if necessary.

4. Replacing the Battery (if needed)

Sub-steps:
1. Remove the old battery by disconnecting the negative terminal first, followed by the positive terminal.
2. Lift the battery out and place the new battery in the tray.
3. Connect the positive terminal followed by the negative terminal.
4. Tighten all connections and ensure the battery is secure.

5. Re-test the System

Sub-steps:
1. Reconnect the negative battery terminal (if previously disconnected).
2. Attempt to start the vehicle again to check if the issue is resolved.
