Solution

1. Preparation

Gather necessary tools and parts, ensuring the vehicle is parked on a flat surface.
Disconnect the battery by removing the negative terminal first (use a socket wrench).

2. Battery Replacement (if required)

Tools Required: Socket set, battery terminal cleaner, torque wrench.
Remove the positive terminal followed by the negative terminal.
Carefully remove the battery from the tray, noting any securing brackets.
Clean the battery terminal connectors with a battery terminal cleaner.
Install the new battery in the reverse order of removal, ensuring tight connections (torque to manufacturer specifications).

3. Starter Motor Replacement (if needed)

Tools Required: Socket set, torque wrench, ratchet extension.
Access the starter by removing any components obstructing its removal (e.g., air intake duct).
Disconnect the electrical connector from the starter and remove the mounting bolts.
Carefully remove the starter motor from the engine bay.
Install the new starter motor, securing it with the mounting bolts (torque to manufacturer specifications).
Reconnect the electrical connector.

4. Fuse Replacement (if applicable)

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box and identify the starter and ignition fuses.
Remove any blown fuses and replace them with new fuses of the same amperage.
