Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery cable to prevent any electrical shorts.
Gather tools: multimeter, socket set, wrench set, and battery terminal cleaner.

2. Battery Inspection and Replacement

Step 2.1: Clean battery terminals
- Use a battery terminal cleaner to remove any corrosion from the terminals.
- Reattach terminals securely.
Step 2.2: Test and replace the battery if necessary
- If the voltage is low or the battery fails the load test, remove the battery using a socket set to disconnect the positive (+) terminal first followed by the negative (-) terminal.
- Install a new battery, ensuring the positive terminal is connected first, then the negative terminal.

3. Starter Motor Inspection

Step 3.1: Locate and remove the starter motor
- Use a socket set to remove any securing bolts and disconnect the electrical connections.
Step 3.2: Test the starter motor
- Use a multimeter to check for continuity and functionality. If the starter motor is defective, replace it.
Step 3.3: Install the new starter motor
- Reconnect the electrical connections and secure the starter motor with bolts. Torque to manufacturer specifications (typically around 15-20 ft-lbs).

4. Final Checks

Reconnect the negative battery cable.
Start the vehicle to confirm proper operation of the starting system.
