Solution

1. Preparation

Gather tools and parts required for the repair.
Tools Required:
- Multimeter
- Socket set
- Torque wrench
- Jumper cables
- OBD-II scanner
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Battery Check and Replacement

Disconnect Battery:
- Use a wrench to loosen the negative (-) terminal first, followed by the positive (+) terminal.
Inspect Battery:
- Check for physical damage, swelling, or corrosion on terminals.
Test Battery Voltage:
- Measure with a multimeter; if below 12.4V, consider charging or replacing it.
Replace Battery:
- If replacement is necessary, remove the old battery and install a new one, ensuring to tighten terminals securely.

3. Starter Motor Inspection

Locate the Starter Motor:
- Refer to the service manual for the exact location.
