Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is in park (automatic) or neutral (manual) to prevent movement.

2. Battery Inspection and Replacement

Inspect Battery Connections:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion using a mixture of baking soda and water, then dry thoroughly.
Test Battery:
- Use a multimeter to measure the battery voltage. If below 12.4 volts, proceed to replace the battery.
Replace Battery (if necessary):
- Remove the old battery (note orientation).
- Install the new battery, connecting the positive terminal first, followed by the negative.
- Ensure terminals are tight and secure.

3. Starter Relay Check

Locate the Starter Relay:
- Open the fuse box cover and locate the starter relay.
Swap Relay:
- Remove the starter relay and swap it with a similar relay from the fuse box.
- Re-test the ignition to see if the clicking noise persists.

4. Starter Motor Inspection

Access Starter Motor:
- Depending on the model, you may need to lift the vehicle for better access.
Inspect Wiring:
- Check the wiring harness connected to the starter motor for wear or disconnection.
Test Starter Motor:
- Use jumper cables to bypass the ignition circuit and directly power the starter motor to see if it engages.
- Replace the starter motor if it does not operate.
