Solution

1. Preparation

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

2. Battery Inspection and Replacement

Inspect Battery Connections
- Use a wrench to tighten any loose connections.
- Clean any corrosion using a mixture of baking soda and water.
Battery Testing
- Connect a multimeter to the battery terminals; if the voltage is below 12.4 volts, replace the battery.
- If the battery is faulty, remove it by:
  - Unscrewing the hold-down bracket.
  - Lifting the battery out of the tray.
Install New Battery
- Place the new battery in the tray.
- Secure it with the hold-down bracket.
- Reconnect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection and Replacement

Check Starter Motor
- If the clicking noise persists, locate the starter motor (typically near the transmission).
- Disconnect the wiring harness and the battery cable from the starter.
Testing and Replacement
- Using a multimeter, test the starter motor for continuity.
- If faulty, remove the starter by:
  - Unscrewing the mounting bolts (usually two or three).
  - Pulling the starter away from the engine block.
Install New Starter
- Position the new starter in place.
- Secure it with the mounting bolts (torque to manufacturer specifications).
- Reconnect the wiring harness and battery cable.
