Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wrenches, wire brush (for cleaning).
Safety Warnings: Disconnect the negative battery terminal before working on the electrical system.

2. Battery Inspection and Replacement

Check Battery Condition: If the battery voltage is low (below 12.4 volts), recharge or replace the battery.
Clean Battery Terminals: Remove the battery cables and clean the terminals and connectors with a wire brush to remove corrosion.
Reconnect Battery: Reattach the battery cables, ensuring they are tight and secure.

3. Starter Relay Replacement

Remove and Test Relay: If the starter relay is determined to be faulty, remove it from the fuse box and replace it with a new one.
Confirm Relay Function: After installation, ensure the relay clicks when the ignition is turned on.

4. Starter Motor Inspection and Replacement

Inspect and Test Starter Motor: If the clicking persists, remove the starter motor for inspection. Test the motor by applying direct battery voltage to it.
Replace Starter Motor: If the starter motor is faulty, replace it with a new unit, ensuring proper alignment and securing it with the specified torque (typically 20-30 Nm).
