Solution

1. Preparation

Ensure the vehicle is in "Park" or "Neutral."
Turn off all electrical accessories.
Gather tools: multimeter, jumper cables, socket set, and safety gloves.

2. Battery Inspection and Replacement

Sub-step 1: Disconnect the negative (-) battery terminal first, followed by the positive (+) terminal.
Sub-step 2: Clean any corrosion from the battery terminals using a wire brush and a mixture of baking soda and water.
Sub-step 3: Reconnect the positive (+) terminal first, followed by the negative (-) terminal.
Sub-step 4: If the battery is faulty, remove it using a socket set and replace it with a new battery of the same specifications.

3. Starter Motor Inspection and Replacement

Sub-step 1: Locate the starter motor, typically near the transmission on the lower side of the engine.
Sub-step 2: Disconnect the wiring harness from the starter motor by gently pulling the connector.
Sub-step 3: Remove the starter motor mounting bolts using the socket set.
Sub-step 4: Carefully take out the starter motor and inspect it for any visible damage.
Sub-step 5: Install the new starter motor by reversing the removal steps and torque the bolts to the manufacturer's specification (usually around 15-20 ft-lbs).
