Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean any corrosion from the terminals and cable ends using a wire brush.
3. Test the battery with a multimeter. If below 12.4 volts, replace the battery.
4. Install the new battery: connect the positive terminal first, followed by the negative terminal.

3. Starter Relay Check

Sub-steps:
1. Locate the fuse box under the hood.
2. Remove the starter relay and visually inspect it for damage.
3. Swap it with a similar relay from the fuse box to test functionality.
4. If the clicking noise persists after replacing the relay, proceed to check the starter motor.

4. Starter Motor Inspection

Sub-steps:
1. Remove any components obstructing access to the starter motor.
2. Disconnect the electrical connections from the starter motor.
3. Remove the starter motor mounting bolts using a socket set.
4. Inspect the starter for wear or damage; replace if necessary.
5. Install the new starter motor and reconnect electrical connections.

5. Ignition Switch Inspection

Sub-steps:
1. Access the ignition switch as per the vehicle’s service manual.
2. Inspect for any signs of wear or malfunction.
3. Replace the ignition switch if faults are detected.
