Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and wrench set.
Ensure safety: Disconnect the battery before starting any electrical work.

2. Battery Inspection and Replacement

Inspect the Battery:
- Check for corrosion at the terminals.
- Clean the terminals using a wire brush and a mixture of baking soda and water.
Test the Battery:
- Use a multimeter to check for voltage.
- If voltage is below 12.4 volts, charge the battery or replace it if it cannot hold a charge.
Replace Battery (if necessary):
- Disconnect negative (-) terminal first, then positive (+) terminal.
- Remove the battery hold-down clamp.
- Carefully lift out the old battery.
- Place the new battery in the tray and secure it with the hold-down clamp.
- Connect the positive (+) terminal first, then the negative (-) terminal.

3. Starter Motor Replacement (if required)

Remove Starter Motor:
- Disconnect the battery again for safety.
- Locate the starter motor (usually near the transmission).
- Remove the electrical connector from the starter.
- Unscrew the mounting bolts using a socket and ratchet.
- Carefully remove the starter motor from its position.
Install New Starter Motor:
- Position the new starter motor in place.
- Reinstall the mounting bolts and torque them to manufacturer specifications (usually around 15-25 ft-lbs).
- Reconnect the electrical connector.
