Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, battery load tester, socket set, torque wrench, and cleaning supplies.
Ensure the vehicle is parked on a flat surface with the engine off and keys removed.

2. Battery Inspection and Cleaning

Check Battery Voltage:
- Use the multimeter to measure the battery voltage. A healthy battery should read around 12.6 volts or higher.
Clean Battery Terminals:
- If corrosion is present, disconnect the negative terminal first, then the positive terminal. Clean terminals and cable ends using a wire brush and a mixture of baking soda and water. Rinse and dry thoroughly.
Reconnect Battery:
- Reconnect the positive terminal first, followed by the negative terminal. Ensure connections are tight.

3. Battery Testing

Test Battery Condition:
- Use a battery load tester to apply a load and check if the battery can maintain a voltage above 9.6 volts under load. If it fails, replace the battery.
Replace Battery (if necessary):
- If replacement is needed, remove the old battery by loosening the hold-down bracket and lifting it out. Install the new battery and secure it properly.

4. Starter Motor Inspection

Visual Inspection:
- Inspect the starter motor wiring for damage or loose connections. Tighten any loose connections.
Test Starter Motor:
- If issues persist, test the starter motor by bypassing the ignition switch using a jumper wire to see if it engages. Replace if faulty.
