Solution

1. Preparation

Gather tools: multimeter, socket set, torque wrench, OBD-II scanner, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Disconnect Battery:
- Use a socket set to remove the negative terminal first, followed by the positive terminal.
- Safety Warning: Always disconnect the negative terminal first to prevent short circuits.
Clean and Inspect:
- Inspect battery terminals for corrosion; clean with a wire brush and a mixture of baking soda and water if necessary.
- Ensure the terminals are tightly connected when reassembling.
Test Battery:
- Reconnect the battery and retest voltage. If under 12.4 volts, replace the battery.
- Battery Replacement:
  - Remove the old battery and replace it with a new one, ensuring proper orientation and secure connections.

3. Starter Motor Inspection

Access Starter Motor:
- Raise the vehicle using jack stands for safety and locate the starter motor.
Inspect Connections:
- Check the wiring and connections to the starter for tightness and corrosion.
- Clean any corroded connections with a wire brush.
Test Starter:
- Use a multimeter to check for voltage at the starter solenoid when the key is turned to the start position.
- If no voltage is present, the starter may need replacement.

4. Replace Starter Motor (if necessary)

Remove Starter:
- Disconnect all wiring from the starter motor.
- Unscrew and remove the starter from its mounting bracket.
Install New Starter:
- Position the new starter in place and secure it with bolts to the mounting bracket.
- Reconnect all wiring to the new starter.

5. Final Assembly

Reconnect the battery terminals, positive first and then negative.
Ensure all tools are removed from the engine bay.
