Solution

1. Preparation

Gather tools: Multimeter, socket set, torque wrench, battery terminal cleaner, and a replacement battery (if necessary).
Ensure the vehicle is in "Park" and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Replacement (if voltage is low)

Remove the negative terminal from the battery.
Remove the positive terminal from the battery.
Unscrew the battery hold-down bracket using a socket set.
Carefully lift the old battery out of the battery tray.
Place the new battery in the tray, ensuring it is oriented correctly.
Reattach the hold-down bracket and tighten to manufacturer specifications (usually 10-12 ft-lbs).
Connect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection (if battery is good)

Locate the starter motor, typically found near the engine's base.
Disconnect the electrical connectors and the battery cable from the starter.
Remove the mounting bolts using a socket set.
Carefully pull the starter motor out and inspect for signs of wear or damage.
If damaged, replace it with a new starter motor, reversing the removal steps to install.
