Solution

1. Preparation

Tools Required: Wrench set, multimeter, OBD-II scanner.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery: Clean any corrosion from terminals using a wire brush and a mixture of baking soda and water.
Test Battery Voltage: If the voltage is below 12.4 volts, charge the battery or replace it if it cannot hold a charge.
Reconnect Battery: Reattach the negative terminal securely.

3. Starter Relay Replacement

Locate Relay: Identify the starter relay in the engine compartment fuse box.
Remove Relay: Pull the relay out of its socket.
Install New Relay: Insert a new relay (if necessary) into the same socket.

4. Starter Motor Inspection and Replacement

Remove Starter Motor: Disconnect the wiring harness and remove the mounting bolts with a socket set.
Inspect Starter: Check for signs of wear or damage. If defective, replace it with a new starter motor.
Reinstall Starter: Position the new starter motor and secure it with bolts. Reconnect the wiring harness.

5. Final Checks

Reconnect Battery: Reconnect the negative terminal.
Test Start: Attempt to start the vehicle to verify the repair.
