Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and battery terminal cleaner.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the battery by removing the negative terminal first.

2. Battery Inspection

Check Voltage
1. Use a multimeter to measure the battery voltage.
2. If the voltage is below 12.4 volts, charge the battery fully.
Clean Terminals
1. Remove the positive and negative battery terminals.
2. Clean any corrosion with a battery terminal cleaner or a mixture of baking soda and water.
3. Reconnect the terminals securely.

3. Starter Relay Test

Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
Swap the relay with another identical relay in the fuse box to test functionality.
If the vehicle starts, replace the faulty relay.

4. Starter Motor Inspection

If the clicking persists, locate the starter motor.
Use a multimeter to check for voltage at the starter while the ignition is turned to the start position.
If no voltage is present, trace the wiring back to the ignition switch.

5. Ground Connection Check

Locate the ground strap connecting the engine to the chassis.
Inspect for corrosion or damage; clean or replace if necessary.
Ensure all connections are tight and secure.

6. Reassemble and Test

Reconnect the battery terminals starting with the positive terminal.
Start the vehicle to check if it cranks and starts properly.
