Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner, screwdriver set.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Battery Connections

Remove the positive and negative battery terminals.
Clean the terminals and battery posts using a battery terminal cleaner.
Reattach the terminals securely and ensure a solid connection.

3. Test and Replace Battery (if necessary)

Sub-steps:
- Use a multimeter to test the battery voltage. If below 12.4 volts, charge or replace the battery.
- If replacing, ensure the new battery matches the required specifications (group size, cold cranking amps).
Reconnect the battery terminals.

4. Inspect and Replace Starter Motor (if faulty)

Sub-steps:
- Locate the starter motor. Usually found near the engine block, accessible from underneath the vehicle.
- Remove the electrical connections from the starter motor.
- Unbolt the starter motor using a socket set.
- Replace with a new starter motor, ensuring the alignment is correct.
- Torque bolts to manufacturer specifications (typically 15-25 ft-lbs).

5. Check and Replace Starter Relay (if necessary)

Sub-steps:
- Locate the starter relay in the fuse box (refer to the owner’s manual for exact location).
- Remove the relay and test it using a multimeter for continuity.
- If faulty, replace with an identical relay.

6. Verify Ignition Switch Functionality (if needed)

If the above steps do not resolve the issue, consider inspecting the ignition switch.
Remove the ignition switch and test for proper operation or replace if defective.
