Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is in a safe, flat location with the engine off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Remove any corrosion from the battery terminals using a wire brush.
- Tighten any loose connections.
Replace Battery (if necessary):
- If the battery voltage is low or the load test fails, remove the old battery by:
  - Disconnecting the positive terminal first, followed by the negative terminal.
  - Removing the battery hold-down clamp.
  - Lifting the battery out of the tray.
- Install the new battery:
  - Place the new battery in the tray.
  - Secure it with the hold-down clamp.
  - Connect the positive terminal first, then the negative terminal.

3. Starter Relay and Fuse Check

Starter Relay:
- Locate the starter relay in the fuse box; consult the owner’s manual for the exact location.
- Remove the relay and check for continuity using a multimeter.
- Replace the relay if it is faulty.
Fuses:
- Identify the fuses associated with the starting system in the fuse box.
- Replace any blown fuses with fuses of the same amperage rating.

4. Starter Motor Inspection

Check Starter Motor:
- If clicking persists, remove the starter motor for inspection:
  - Disconnect the electrical connections to the starter.
  - Remove the mounting bolts using a socket set.
  - Pull the starter motor out of its housing.
- Test the starter motor by connecting it directly to the battery; if it does not engage, replace it.
