Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe position with the parking brake engaged.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect the battery for any signs of damage or leakage.
If the battery voltage is low (below 12.4 volts), charge the battery using an appropriate battery charger.
If the battery is more than three years old or unable to hold a charge, replace it with a new one.
- Tools Required: Battery terminal cleaner, wrench set, battery charger.
- Parts Required: New battery (if required).
- Safety Warning: Wear gloves and safety glasses while handling the battery.

3. Starter and Relay Inspection

Locate the starter motor and inspect it for any signs of damage or loose connections.
If the starter relay was determined faulty during diagnostics, replace it.
- Tools Required: Socket set, screwdriver.
- Parts Required: New starter relay (if applicable).

4. Starter Replacement (if necessary)

Remove the mounting bolts securing the starter motor.
Disconnect the electrical connectors from the starter.
Install the new starter by reversing the removal steps.
- Torque Specification: Refer to the service manual for the correct torque values for the starter mounting bolts.
- Safety Warning: Ensure the negative battery terminal is reconnected after the installation.
