Solution

1. Preparation

Gather necessary tools and parts: OBD-II scanner, multimeter, socket set, torque wrench, battery cleaner, new battery (if needed).
Ensure the vehicle is in a safe and level area with the parking brake applied.

2. Battery Inspection and Replacement

Disconnect Battery:
- Use a socket wrench to remove the negative (-) terminal first, followed by the positive (+) terminal.
- Safety warning: Disconnect the battery before working on electrical systems to avoid short circuits.
Clean Battery Terminals:
- Use a battery cleaner to remove corrosion from the terminals and cable ends.
- Reconnect and tighten the terminals securely after cleaning.
Battery Testing:
- If the battery voltage is low, use a battery tester to perform a load test.
- If the battery fails the load test, proceed to replace it.
Replace Battery (if needed):
- Remove the old battery from the tray.
- Place the new battery in the tray and secure it with the hold-down bracket.
- Connect the positive (+) terminal first, followed by the negative (-) terminal.

3. Starter Relay and Wiring Check

Inspect and Test Starter Relay:
- Identify the starter relay in the fuse box.
- Swap it with a similar relay to confirm if the relay is faulty.
Check Wiring:
- Visually inspect wires from the battery to the starter for signs of wear or damage.
- Ensure all connections are tight and free from corrosion.
Ignition Switch Inspection:
- If previous steps do not resolve the issue, consider testing or replacing the ignition switch as it may not be sending a start signal to the starter solenoid.
