Solution

1. Preparation

Tools Required: Multimeter, socket set, wrench set, battery terminal cleaner, safety gloves, safety goggles.
Disconnect the negative battery cable to prevent electrical shock.

2. Inspect and Clean Battery Terminals

Remove the positive (+) and negative (-) battery terminals using a wrench.
Clean corrosion using a battery terminal cleaner or a mixture of baking soda and water.
Reconnect the terminals, ensuring they are tight.

3. Test and Replace the Battery (if necessary)

Reconnect the battery and perform a voltage check with the multimeter.
If the voltage is below 12.4 volts or the load test fails, replace the battery.
- Remove the battery hold-down bracket.
- Lift the battery out of the tray carefully.
- Install the new battery in reverse order.

4. Check and Replace the Starter Relay

Locate the starter relay in the fuse box (refer to the vehicle manual for exact location).
Swap the starter relay with a similar one to test functionality.
If the vehicle starts, replace the faulty relay.

5. Inspect and Replace the Starter (if necessary)

If the clicking persists, the starter may be faulty.
Disconnect the negative battery cable again.
Remove the starter by unbolting it from the mounting bracket (typically 2-3 bolts).
Disconnect the electrical connectors from the starter.
Install the new starter by reversing these steps, ensuring all connections are secure.
