Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, jumper cables.
Ensure the vehicle is in park and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery Connections:
- Clean battery terminals with a wire brush to remove corrosion.
- Tighten loose connections securely.
Test Battery:
- Reconnect the battery and test the voltage again. If still low, replace the battery.
Replace Battery (if necessary):
- Remove the old battery using a socket set, noting the connections.
- Install the new battery, ensuring correct polarity, and secure it.

3. Starter Motor Check

Bypass Starter Motor:
- Connect jumper cables from the battery directly to the starter motor terminals.
- If the starter engages, it may need replacement.
Remove Starter Motor:
- Disconnect the battery again.
- Unbolt the starter motor from its mount using a socket set.
- Replace with a new starter motor if faulty.

4. Fuse Inspection

Check Fuses:
- Locate the fuse box and check the starter-related fuses.
- Replace any blown fuses with the same amperage rating.

5. Final Assembly

Reconnect the negative battery terminal securely.
Ensure all components are properly installed and secured.
Close the fuse box and any access panels.
