Solution

1. Preparation

Gather tools: Multimeter, socket set, torque wrench, OBD-II scanner, and safety gloves.
Ensure the vehicle is in park and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Check Battery Condition
- Clean battery terminals with a wire brush if corroded.
- Reconnect the battery terminals securely.
Replace Battery (if required)
- Remove the battery hold-down clamp using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery from the tray.
- Install the new battery in reverse order, ensuring correct terminal connections (positive to positive, negative to negative).
- Tighten the battery terminals to prevent movement (generally 10-15 Nm).

3. Starter Motor Inspection and Replacement

Inspect Starter Motor
- Locate the starter motor (usually near the transmission bell housing).
- Check for loose or damaged wiring connected to the starter.
Replace Starter Motor (if necessary)
- Disconnect the battery negative terminal again.
- Remove the electrical connections from the starter.
- Unbolt the starter motor from the engine using a socket set (typically requires 10-15 Nm torque).
- Install the new starter motor and secure it with bolts.
- Reconnect the electrical connections to the starter.
- Reconnect the negative battery terminal.
