Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, battery terminal cleaner, and safety goggles.
Ensure the vehicle is in park and the parking brake is engaged.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Clean Battery Terminals

Remove the positive cable first, then the negative cable.
Use a battery terminal cleaner to remove corrosion from the terminals and cable ends.
Reconnect the negative terminal followed by the positive terminal, ensuring they are tight.

3. Test and Replace Battery (if necessary)

If the battery voltage is below 12.4 volts, perform a load test. If it fails, replace the battery.
Install a new battery by connecting the positive terminal first, followed by the negative terminal, ensuring secure connections.

4. Check and Replace Starter Relay

Locate the starter relay in the fuse box.
Remove the relay and test its operation by swapping it with a similar relay.
If the vehicle starts with the swapped relay, replace the faulty starter relay.

5. Inspect and Replace the Starter Motor (if necessary)

If the clicking persists, locate the starter motor (attached to the transmission bell housing).
Disconnect the wiring harness and remove the mounting bolts using a socket set.
Inspect the starter motor for signs of wear or damage; replace if necessary.
Install the new starter motor and reconnect the wiring harness.
