Solution

1. Preparation

Tools Required:
- Socket set
- Multimeter
- Battery terminal cleaner
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Clean the battery terminals using a battery terminal cleaner to remove corrosion.
Reconnect the battery terminals securely.
If the battery voltage is below 12.4 volts or the battery is weak, replace it.
- Sub-steps:
  - Remove the old battery by unbolting the hold-down clamp and disconnecting the positive terminal first, then the negative terminal.
  - Install the new battery by connecting the positive terminal first, followed by the negative terminal.
  - Secure the battery with the hold-down clamp.

3. Starter Motor Check

If the battery is in good condition, check the starter motor.
- Sub-steps:
  - Locate the starter motor under the vehicle (typically near the transmission).
  - Inspect the electrical connections to the starter for tightness and signs of wear.
  - If necessary, remove the starter motor by unbolting it (check manufacturer torque specifications for reinstallation).
  - Test the starter motor using a bench test or replace if faulty.

4. Fuse and Relay Inspection

Check the starter relay and fuses for any faults.
- Sub-steps:
  - Locate the fuse box (refer to the owner's manual for exact location).
  - Inspect the relevant fuses and replace any that are blown.
  - Test the starter relay by swapping it with a similar relay in the fuse box.
