Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, jump starter, remote starter switch.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to sit for a few minutes if jump-starting, to avoid damaging the electrical system.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean any corrosion with a battery terminal cleaner or a mixture of baking soda and water.
Reconnect the terminals securely, ensuring a tight fit.

3. Starter Replacement (if necessary)

Tools Required: Socket set, torque wrench, screwdrivers, safety goggles.
Remove the battery again if it is still connected and disconnect the negative terminal.
Locate the starter motor (usually near the transmission).
Remove the electrical connections to the starter using a socket set.
Unbolt the starter motor from its mount, typically secured with 2-3 bolts.
Install the new starter by reversing the removal steps, ensuring all bolts are torqued to the manufacturer specifications (typically around 15-25 ft-lbs).
Reconnect the battery terminals (positive first, then negative).

4. Verification of Repair

Reconnect the negative battery terminal.
Attempt to start the vehicle and listen for the starter engagement.
Check for voltage at the starter motor using a multimeter when the ignition is turned to the start position.
If the vehicle starts, monitor for any unusual noises or warning lights.
