Solution

1. Preparation

Tools Required: Multimeter, wrench set, battery terminal cleaning brush, jump starter (if needed).
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Cleaning

Sub-steps:
1. Remove the positive battery terminal followed by the negative terminal.
2. Clean the battery terminals and cable ends with a battery terminal cleaning brush to remove corrosion.
3. Reconnect the terminals, starting with the positive, then the negative.

3. Battery Replacement (if necessary)

Sub-steps:
1. If the battery voltage is below 12.4 volts or fails the load test, remove the old battery by unbolting the hold-down bracket.
2. Install the new battery in the reverse order, ensuring the positive terminal is connected first.
3. Tighten the terminals securely and apply a corrosion inhibitor if available.

4. Starter Relay and Fuse Check

Sub-steps:
1. Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
2. Swap the starter relay with a similar relay to test if the original relay is faulty.
3. Inspect and replace any blown fuses in the starting system circuit.

5. Starter Motor Inspection

Sub-steps:
1. If the problem persists, locate the starter motor (usually mounted near the transmission).
2. Check the wiring harness connected to the starter for damage or loose connections.
3. If necessary, remove the starter motor and bench test it using jumper cables to verify functionality.
