Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, basic hand tools
Safety Warnings: Disconnect the negative battery terminal before starting work on electrical components.

2. Battery Inspection and Replacement

Check Battery Condition:
- Remove the battery terminals (negative first).
- Clean any corrosion from the terminals using a wire brush.
- Reconnect and test the battery voltage again; if below 12.4 volts, consider charging or replacing the battery.
Replace Battery (if necessary):
- Remove the old battery by loosening the hold-down brackets and lifting it out.
- Install the new battery, ensuring proper orientation and securing the hold-down.
- Reconnect the terminals (positive first, then negative).

3. Starter System Inspection

Check Starter Wiring:
- Inspect the wiring harness connected to the starter for any signs of damage or loose connections.
- Ensure the connections are clean and tight.
Starter Replacement (if faulty):
- Disconnect the battery again.
- Remove the wiring from the starter motor.
- Remove any bolts securing the starter in place using a socket set.
- Install the new starter by reversing the removal steps, ensuring all connections are secure.
