Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic socket set, wrench set.
Park the vehicle on a flat surface and set the parking brake.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals, starting with the negative (-) terminal.
2. Inspect the battery for any signs of swelling, leaks, or corrosion.
3. Clean the terminals with a wire brush and a baking soda solution if corrosion is present.
4. Reconnect the terminals securely.

3. Battery Replacement (if needed)

Sub-steps:
1. If the battery voltage is below 12.6 volts, replace it. Disconnect the negative terminal first, then the positive (+).
2. Remove the battery hold-down bracket and lift the battery out.
3. Install the new battery, connecting the positive terminal first, followed by the negative terminal.
4. Ensure all connections are tight and secure.

4. Starter Inspection

Sub-steps:
1. If the battery is fine, locate the starter motor (usually near the engine transaxle).
2. Disconnect the electrical connector and the power cable from the starter.
3. Test the starter solenoid with a multimeter; it should show continuity when activated.
4. If the solenoid or starter is faulty, remove the starter by unbolting it and replace it with a new or refurbished unit.
