Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jumper cables, torque wrench.
Ensure the vehicle is in a safe, well-ventilated area and on a flat surface.

2. Battery Check

Disconnect the Battery: Remove the negative terminal first, followed by the positive terminal.
Clean Battery Terminals: Use a wire brush to remove any corrosion from terminals and connectors.
Test Battery Voltage: Reconnect the multimeter to check voltage; replace battery if below 12.4 volts.

3. Starter Motor Inspection

Access the Starter: Remove any covers or shields as needed to access the starter motor.
Inspect Wiring: Check for loose or damaged wires connected to the starter.
Test the Starter: Use jumper cables to apply power directly to the starter. If it clicks but does not turn, replace the starter motor.

4. Replace Components (if necessary)

Remove the Old Starter: Unbolt the starter from its mounting and disconnect wiring.
Install New Starter: Position the new starter in place, reconnect wiring, and secure it with bolts to the specified torque (check manufacturer specs).
Reconnect Battery: Attach the positive terminal first, followed by the negative terminal.
