Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, and safety gloves.
Disconnect the battery negative terminal to prevent any electrical shock or shorts.

2. Battery Inspection and Replacement

Check Battery Health: If the battery voltage is low, charge or replace the battery.
Clean Terminals: Remove corrosion from battery terminals using a wire brush and a mixture of baking soda and water.
Reconnect Battery: Ensure the terminals are tightly connected and secure.

3. Starter Relay Replacement

Locate the Relay: Find the starter relay in the fuse box as per the owner's manual.
Remove Old Relay: Use the socket set to unscrew any retaining screws and pull out the faulty relay.
Install New Relay: Insert a new relay in the same position and secure it with screws.

4. Starter Motor Testing and Replacement

Inspect Connections: Check the connections to the starter motor for tightness and corrosion. Clean if necessary.
Test Starter Motor: Use the multimeter to check the voltage at the starter motor when the ignition is turned on.
Replace Starter Motor: If the starter motor is found defective, remove it (typically requires removing bolts and disconnecting wires) and install a new one, ensuring proper torque specifications are followed.
